Rain likely in Northern California as late-season system arrives from the Pacific

A low-pressure trough pushing into Northern California from the Pacific will bring widespread showers to the part of the state most in need of rain.

A low-pressure trough pushing into Northern California from the eastern Pacific will bring widespread showers to the part of the state most in need of rain.
The trough is expected to push a cold front into Northern California Monday morning through Monday evening, causing widespread showers and breezy southwest winds gusting 25 to 40 mph in the higher elevations, the National Weather Service said. Showers will continue Monday night and Tuesday as the trough itself pushes through, and weak instability could cause thundershowers. High temperatures will be 5 to 10 degrees below average on Monday, and as much as 20 degrees below average on Tuesday.
To the south, the cold front associated with the trough will bring a deep marine layer and a slight chance of light rain, mainly in San Luis Obispo and Santa Barbara counties, on Monday night and Tuesday morning.
The rainfall in Northern California will not be enough to alleviate the ongoing drought, but it could delay the start of the fire season a little. The National Interagency Fire Center has predicted above-normal potential for large wildfires by midsummer.

The portion of California in moderate drought increased from about 22% to 23.3%, and the portion in severe drought expanded from 14.9% to 15.6%.
The part of the state up by the Oregon border that is in extreme drought declined from 4.7% to 3.9%. May got off to a wet start as 1 to 3 inches or more of rain fell on coastal southwest Oregon and extreme northwest California, the U.S. Drought Monitor reported.

Otherwise, precipitation for the water year to date since Oct. 1 has averaged less than 50% of normal across parts of Oregon, Northern California and the Great Basin.
The portion of the California not considered to be in drought, mainly in the southern and central part of the state, remained at 41.8%. Southern California benefited from some winter-like late-season storms, but has since baked under persistent heat waves as a summer-like ridge of high pressure has camped over California and the Southwest.
This week’s upper-level trough is expected to be slow to move out, so showers could linger in Northern California into Wednesday and Thursday before high pressure and dry, warmer weather return to that part of the state. But long-range trends suggest another trough could bring another late-season rain chance to Northern California around May 17.

California faces a perilous fire season as coronavirus threatens firefighters

As California’s wildfire season approaches, authorities are worried about their ability to muster a healthy firefighter force amid coronavirus crisis.

As forecasters predict higher-than-normal chances of large fires in Northern California this year — as well as the usual risk of “large significant” burning in Southern California — fire authorities are growing increasingly concerned over their ability to muster a large, healthy force of firefighters in the face of COVID-19.
Realizing that wildfire smoke will steadily impair a firefighter’s immune system, and that traditional base camps can magnify the risk of infection, federal, state and county officials are urging a blitzkrieg approach to wildfires that will rely heavily on the use of aircraft.
With the coronavirus still circulating, they say they cannot allow even the smallest secluded fire to smolder for the sake of forest ecology. All fires, they say, must be extinguished as quickly as possible.

“Unfortunately, this is not a year in which we can afford to assign firefighters to monitor and manage such wildland fires,” Sen. Lisa Murkowski (R-Alaska) wrote to the departments of Interior and Agriculture recently as she urged aggressive firefighting in Northern California and other parts of the West. “Given the unprecedented conditions in this fire season, it is essential to utilize federal resources for immediate wildfire suppression to the greatest extent practicable.”
The call for highly aggressive firefighting marks a return to an older ethos, particularly on federal lands, where most California forests are.
For most of the last century, the federal government’s policy was to knock down every fire wherever it sprang up. In recent decades however, a different approach has evolved: Fires that don’t pose a threat to the public are allowed to expand naturally, and burn away overgrowth. That is unlikely to be the case this fire season however, as protections against the spread of the coronavirus place new strains on fire agencies and their crews.
In many ways, the coronavirus is sending wildland firefighters back to the old school this fire season.

“Aggressive initial attack is the single most important method to ensure the safety of firefighters and the public; it also limits suppression costs,” said Jessica Gardetto, a spokesperson for the Bureau of Land Management at the National Interagency Fire Center.
Even with the increased use of aircraft however, fire authorities still face a hard reality. Planes and helicopters are effective in slowing most fires, and allow crews on the ground to get on the scene and contain it, but history shows they do little to halt the wind-driven monsters that cause the most death and destruction.
The continued spread of the coronavirus, as well as the economic paralysis that has accompanied health restrictions, has impacted every aspect of wildland firefighting, including mutual aid arrangements and the widespread use of inmate firefighters.
“Speaking across the board, this is a game changer with COVID-19,” said Mike Mohler, spokesman for the California Department of Forestry and Fire Protection. “It’s going to have to be an ‘everybody’s hands on deck’ approach to this.”

Mohler said his biggest concern is firefighters contracting COVID-19 and silently spreading it among fellow firefighters and knocking them out of service, or even spreading it among the public.
Already, the coronavirus has reduced the number of overall firefighters available in California.
When coronavirus infections spiked in state prisons, authorities granted early release to thousands of minimum-security inmates in an effort to reduce crowding and slow the spread of disease. Of those releases, 242 were inmate firefighters, according to the California Department of Corrections and Rehabilitation. Inmate firefighters make up 43% of the state firefighting force.
In Los Angeles County, where voters recently rejected a measure to hire more firefighters and paramedics, Fire Chief Daryl Osby said potential staffing shortages and increased brush growth due to late-spring rains are cause for worry.

Aiming to take a more aggressive posture toward wildfires, crews are preparing five of the county’s water-dropping helicopters to deploy during the day and night throughout the summer. The county is also planning to contract with two air tankers from Canada in August — a month earlier than usual, Osby said.
And, later this month, crews will begin inspecting wildfire-vulnerable homes to ensure that they have fire defensible space.
“It’s going to be really important for our citizens to do the proper brush clearance,” Osby said, “because when we get toward the fall months and start having our wind-driven incidents, we cannot guarantee to place an engine at every home.”
Traditionally, California has been able to rely on its mutual-aid system for backup. The system, which sends local fire departments to battle wildfires in other jurisdictions, is experiencing heavy strain that could intensify as COVID-19-related budget shortfalls hit municipalities hard.

Among them is the Seaside Fire Department in Monterey County, where the firefighters’ union recently agreed to a 10% pay cut amid a citywide hiring freeze. Layoffs and early retirements that were being considered have been avoided for now, said Jason Black, the president of the firefighters union.
But for how long is unclear.
“I don’t have a crystal ball,” Black said, “it’s like everybody else, it depends on the rebound of the economy as the shelter in place gets lifted.”

In an effort to limit the transmission of illness among wildland firefighters, officials are adjusting the layout at fire base camps, where fire crews traditionally eat, sleep and bathe in close quarters, along with many caterers and contractors. Even before the COVID-19 pandemic, outbreaks of “camp crud” were notorious in such environments, and a union representative for the U.S. Forest Service has likened them to “cruise ships on land.”
Cal Fire said its camps may end up taking up a larger footprint, such as two fairgrounds instead of one, or a large parking lot, to provide adequate spacing among crews.
Either way, firefighters battling flames on the front lines and communities downwind will be more vulnerable to infection because of their smoke exposure, said Dr. John Balmes, a volunteer physician with the American Lung Assn. and a member of the California Air Resources Board.
“Wildfire smoke is kind of like cigarette smoke — a mixture of carbon-based particles and irritant gases,” Balmes said. With the body’s immune system preoccupied battling these foreign invaders in the lungs, that gives it less ammunition to fight the coronavirus, Balmes explained.

In California, a soggy spring has so far kept the 2020 fire season at bay. In states where fires have already begun however, fire crews are learning that protections against the coronavirus — cleaning, distancing and wearing masks — can become burdens when trying to respond to wildfires.
Shawn Faiella, superintendent of the Lolo National Forest’s interagency hotshot crew in Montana, summed it up this way in a report to the federally funded Wildland Fire Lessons Learned Center: “It is damn tough to take these practices to the fireline.”
On the long drive to an incident, firefighters avoided drinking water, out of concern about touching their face masks, and increased their risk of dehydration. They also traveled in more vehicles than usual, to ensure proper distancing, and thereby increased their chances of a crash — one of the leading causes of death for firefighters.
“If this had been an emerging incident with evacuations, tight road parking, smoke, and significant fire growth, not only would this be an impossible feat to park all the vehicles — we would be putting my crew in significant danger. And we just arrived on incident,” Faiella wrote.

Finding places to eat in states with shelter-at-home orders proved difficult as well, as did maintaining social distance with colleagues on the fire line and the public who approached with questions. Routine things to speed up a firefight like sharing equipment between agencies now violate COVID-19 guidelines.
“If the intent is to fight fire, there needs to be an understanding that COVID-19 social distancing recommendations cannot be fully adhered to when engaged in firefighting,” read a report from the April 17 Verde fire in Colorado. “The question needs to be answered: does a lack of completely adhering to COVID measures mean less engagement or not?”
Frank Carroll, a retired 31-year veteran of the U.S. Forest Service, has a son who is a federal hotshot firefighter. He and his fellow crew members were looking to older practices in firefighting in order to deal with coronavirus concerns.
For example, his son’s crew started loading extra vehicles with 14 days’ worth of rations for each firefighter, in case they get infected and have to quarantine, then march into the forest and eat and sleep where they work, instead of returning to a large base camp with hundreds of others.

“It’s really old school but you know what? Old school worked really well,” Carroll said.

Desert mystery: Why have pronghorn antelope returned to Death Valley?

Desert naturalists are unsure why pronghorn antelope have returned to one of the hottest places on earth. Will they be in a pickle this summer?
Published

More than a century after railroads, ranchers and hunters vanquished their ancestors, pronghorn antelope are returning to this unforgiving expanse of desert along the California-Nevada border.
A photo of a lone male and a harem of five does shared on Death Valley’s Facebook page in late April was only the latest indication that the American pronghorn, North America’s land speed champion, may be extending its migratory range into the Mojave Desert once again from cooler seas of sage nearly 100 miles to the north and east.
“It’s not all gloom and doom, woohoo!” the nonprofit National Parks Conservation Assn. announced to wildlife advocates nationwide. “If nothing else, enjoy the feel-good photo and I hope you’re doing well.”
The pronghorn’s reappearance here is a bit of a mystery, as most animal species are making tracks for higher and cooler elevations as the climate warms. Some say the interloping antelope could find themselves in dire straits once summer heat blankets the park.

Along with the recent photo, park officials noted: “Pronghorn may be some of the newest residents to our park! While on patrol, rangers have recently spotted a herd of these quick-footed animals and at least one lone male exploring the park, likely the result of a migration that has been years in the making.
“While pronghorn have been witnessed in the park on occasion for the past two years,” they added, “this increase in their presence suggests these graceful creatures may become long-term residents of the valley.”
Recently, a group of biologists spent the morning photographing a doe that was guarding a newly born fawn in a patch of desert scrub just east of the park’s northern boundary near the town of Beatty, Nev.
Additional analysis is needed to determine whether the deer-like animals with forward jutting black horns are establishing residency in the usually desolate 3.3-million-acre park. In the meantime, their spring season ventures into the Mojave in recent years open the door to some obvious questions.

Exactly where are they coming from? Are they rediscovering ancient migratory routes in arid lands punctuated by scattered mountains and plateaus or creating new pathways into areas where drought and rising temperatures are upsetting the delicate balance between life and death for such species as desert tortoises and Joshua trees?
One biologist who has been tracking recent pronghorn wanderings from the Ubehebe Craters volcanic field in the northern half of Death Valley to the tiny desert berg of Shoshone near the park’s southern end has proposed an answer.

“Pronghorn are following lush buffets of rain-fed wildflowers,” said Laura Cunningham, California director of the nonprofit Western Watersheds Project and a resident of Beatty, about five miles east of the park.
“We’ve been getting some nice blooms triggered by erratic storms in the higher elevations of the northern Mojave Desert over the past five years or so,” she said. “By piecing storm events, wildflower blooms and reported pronghorn sightings together, it’s hard not to think that there may well be new migratory patterns unfolding before our eyes.”
“In other words,” she added, “Pronghorn are taking a giant step out of the sage and into the desert to dine on the flowers of spring in the northern Mojave: [Desert] dandelions, desert pincushions, primrose and desert golds.”
Kathleen Longshore, a research biologist with the U.S. Geological Survey, would not go that far. But she pointed out that seasonal rainfall patterns vary significantly over the national park and can have huge ecological consequences.
It is not all that unusual for northern sections of the park to get hammered by late-winter storms that alter the rugged landscape with layers of mud and rocks and refresh the entire landscape with carpets of grass and wildflowers.
“We can test Laura’s theory,” Longshore suggested, by documenting the movements of members of a pronghorn population in the Nevada National Security Site, about 50 miles northeast of Death Valley’s boundary line, that were recently fitted with tracking collars.
“They’re not going to hang around in the desert much longer. The Mojave is a tough place for pronghorn in summer.”

“It shouldn’t be difficult to determine whether some of the pronghorn showing up farther south than they should be may have wandered out of that Nevada security site herd to browse land that greened up after seasonal storms,” she said.
In any case, she added, “They’re not going to hang around in the desert much longer. The Mojave is a tough place for pronghorn in summer.”
Pat Cummings, a game biologist with the Nevada Department of Wildlife, agrees. “If those animals don’t have a source of standing water, they’re going to be in a pickle,” he said. “In Death Valley, the party is over in June.”
The highest temperature ever recorded on the planet was in Death Valley on July 10, 1913 — 134 degrees.
The park’s headquarters in Furnace Creek is 190 feet below sea level. Nearby Badwater, at 282 feet below sea level, is the lowest spot in the Western Hemisphere. On summer days, some visitors crack eggs there just to watch them fry in the heat, inadvertently creating problems for park staffers by attracting coyotes.

Scientists say pronghorn evolved in cooler climates when the Western Hemisphere was home to the American cheetah and, in order to survive, they developed superb survival equipment — speed and vision. When threatened, pronghorn, which have been clocked in bursts of 60 mph, do not run for cover, but for wide open spaces.
Prior to the westward expansion an estimated 40 million pronghorn inhabited the grassland, deserts and sagebrush flats of western North America from Canada’s prairies to northern Mexico. By the early 20th century, their numbers had been reduced to fewer than 20,000.
Bucks weigh up to 150 pounds, does around 90. From ground to shoulder they stand about 36 inches high. Pronghorn have large eyes that protrude from the skull, giving them a field of view of more than 300 degrees.

Before the mid-19th century, pronghorn roamed the hills and flatlands of the San Fernando, San Gabriel, Antelope, Perris and Moreno valleys and the Baldwin Hills. In his book “Here Roamed the Antelope,” Glenn A. Settle quoted Antelope Valley pioneer John D. Covington (1867-1949):
“When I was a boy, 30 cowboys and myself made a count one day and counted, as nearly as we could, 7,000 antelope.”

In a 1906 book, “California’s Mammals,” Frank Stephens wrote: “In 1877 I saw two dozen antelope near Perris. In 1878 I saw one near Riverside. Today [1906], there are very few in southeastern California.”
Now, pronghorn have joined a small but growing list of animals reclaiming ancient haunts without the help of costly, and often controversial, state and federal reintroduction projects. Among them are wolves in Northern California forests and Pacific fishers, red foxes and wolverines clinging to survival in the cold, steep slopes of the Sierra Nevada range.
Peering through binoculars at the doe nibbling wildflowers near where her kid was hiding, motionless, in grass and desert shrub from predators, Cunningham mused to no one in particular, “Wouldn’t it be great to see baby pronghorn taking their first steps in Death Valley?”

Snow and Cold in May: A ‘Nerve-Racking’ Time for Growers

The coronavirus pademic was already making life on the farm unpredictable, and then came an Arctic blast.
Published

Across New York and New England, farmers and growers watched with worry on Saturday morning as a late season blast of Arctic air and even snow descended on fragile fruits and vegetables that had just begun to poke through.
Workers at Westwind Orchard in Accord, N.Y., about 70 miles south of Albany, on Friday night sprayed water, molasses and kelp mineral on budding apple blossoms to help protect them against the cold.
By 5 a.m. on Saturday, growers were on the phone with each other to learn what kind of damage the unseasonable weather had unleashed.
“What we’re experiencing is nerve-racking and very unusual,” said Mike Biltonen, a pomologist who runs Know Your Roots, a small apple orchard and consulting company in Hector, N.Y., in the Finger Lakes region, about 20 miles west of Ithaca.
In New Hampshire, Massachusetts and Maine, people woke up on Saturday to find snow falling. The temperature in Worcester, Mass., fell to 30 degrees, breaking the previous record of 31 set on May 9, 1934, according to the National Weather Service.
At Bigelow Nurseries in Northborough, Mass., workers stayed hours after closing on Friday, pulling in annuals like begonias and petunias. They then covered the hydrangeas and Japanese maple trees, which had just started growing, with garden cloth to keep the blooms from dying.
“We had to scramble,” said Nick Steiman, a wholesale representative at the nursery. “Nothing got lost. It’s definitely going to slow down new growth but we didn’t have any fatalities.”
In parts of Massachusetts, forecasters warned of wind gusts of up 50 miles an hour through Saturday evening. The Weather Service warned of low temperatures through Sunday morning.
“Gusty winds could blow around unsecured objects,” the National Weather Service said. “Tree limbs could be blown down and a few power outages may result. Freeze conditions will kill crops and other sensitive vegetation.”
It was not the kind of forecast that farmers needed to hear as they continue to worry about how the coronavirus pandemic might affect their industry and the critical months in the summer and fall, when tourists come for the pick-your-own season or to drink cider on the sprawling acres.
Fabio Chizzola, the owner of Westwind Orchard, where tourists come for cider, pizza and Italian food, said he had managed to keep the business going during the pandemic by offering takeout.
He said he was lucky to not have had to lay off any workers, but the slog of isolating at home, then driving to the farm to work has become tiring.
“It’s been tough,” Mr. Chizzola said. “We’ve been quarantining and then you work, work, work, and then you go home and then work, work, work.”
John Wightman, owner of Wightman Fruit Farm in Kerhonkson, N.Y., says his apple trees are planted well above sea level and are closer to the warm air. Still, he said, he doesn’t know yet how the low temperatures will affect his apple trees.
“I still think I have a crop swinging,” he said. “It’s not doomsday. We’re cautiously optimistic that we’re going to persevere and have a crop, but it’s not in our hands.”
As unsettling as the weekend weather was, it was still better than April, when temperatures dipped to 23 degrees in parts of New York State, killing pear trees and damaging peaches, sweet cherries and apricots.
The temperature is expected to rise into the 50s on Sunday but fall again overnight before balmier weather returns on Tuesday.
Around the Finger Lakes, the temperature fell to 27 degrees overnight on Friday. It was cold but warm enough that farmers were able to protect their crops from destruction, Mr. Biltonen, the pomologist, said.
“If we had gotten down to 26, 25, 24 degrees, we’d be having tequila shots this morning,” he said.
