Now Tropical Storm Marco loses strength as Tropical Storm Laura grows forming dual threat to Gulf Coast; Florida Keys under tropical storm watch
Marco lost strength while Laura gained strength as two tropical storms threaten the Gulf Coast, according to FOX 35 meteorologists.
With slight weakening late Sunday, what was Category 1 Hurricane Marco, which had formed in the central Gulf of Mexico earlier in the day, fell back to Tropical Storm Marco with maximum winds of up to 70 mph as Tropical Storm Laura grew in strength to 65 mph — a potential double whammy for the U.S. Gulf Coast, according to the National Hurricane Center.

At 11 p.m., Marco was located about 185 miles south-southeast of the mouth of the Mississippi River. The storm was moving north-northwest at 12 mph, the hurricane center said.

Marco, which is expected to near the Louisiana coast Monday afternoon, will likely weaken after it makes landfall, according to the NHC.
“Small fluctuations in strength are possible [Sunday night]. Gradual weakening is expected to begin on Monday, and Marco could become a remnant low by Tuesday night,” forecasters said.

The areas from Morgan City, Louisiana to the mouth of the Pearl River are under a hurricane warning from the NHC. A hurricane watch is in effect for Lake Pontchartrain, Lake Maurepas and metro New Orleans. All of those areas are also under a tropical storm warning while a tropical storm watch is in effect from the Mississippi-Alabama border to the Alabama-Florida border.

A storm surge warning remains in effect from Morgan City to Ocean Springs and Lake Borgne.
Marco is expected to produce between two to four inches of rain, and potentially up to a maximum of six inches, across the central U.S. Gulf Coast through Tuesday, the NHC said.
“This rainfall may result in isolated areas of flash and urban flooding along the Central U.S. Gulf Coast,” forecasters said.
Meanwhile, Tropical Storm Laura dumped heavy rain and life-threatening flash flooding over parts of eastern Cuba, Haiti and Jamaica. Forecasters expect Laura to transform into a hurricane late Tuesday.
Both Marco and Laura will narrowly avoid Florida, but the state will still see an indirect impact by way of wind gusts and rainfall and the Dry Tortugas were placed in a tropical storm warning late Sunday.
“Florida is on the eastern side of both of those systems, so that means we are going to be seeing an increase in winds; an increase in tropical moisture, so more rain chances; and the potential for more tornado activity,” Fox-35 meteorologist Allison Gargaro said.
Gargaro said the potential for tornado activity is higher for more southern communities, according to data from the National Weather Service.
Laura’s latest track showed the storm still churning along its path toward the Gulf of Mexico in what may become a historic clash of two storms simultaneously threatening the U.S. Gulf Coast.

At 11 p.m. Sunday, the NHC said, the center of Tropical Storm Laura was located about 125 miles southeast of the Camaguey, Cuba. Maximum-sustained winds were 65 mph with higher gusts, and tropical-storm-force winds extended outward up to 140 miles. The storm was moving west-northwest at 21 mph.
Laura is expected to produce heavy rainfall and life-threatening flash flooding over parts of the Dominican Republic and Haiti, the Turks and Caicos, the southeastern Bahamas, and Cuba on Sunday, and this activity is expected to continue through Monday, the NHC said.
Laura is forecast to move into the Gulf of Mexico Monday and strengthen into a hurricane with an expected landfall in Louisiana or Mississippi – just days after Marco makes landfall in the same area, likely also as a hurricane.
“Strengthening is forecast after the storm moves over the Gulf of Mexico, and Laura is forecast to become a hurricane late Tuesday or Tuesday night,” forecasters said.
While the tropical storm warning was issued for the Dry Tortugas late Sunday, a tropical storm watch is in effect for the Florida Keys from Craig Key to Key West.
A tropical storm warning remains in effect for parts of Cuba and the Cayman Islands.
Will Tropical Storms Laura and Marco clash?
The two storms’ forecast tracks appear to clash in the gulf, but as they crawl closer along their paths, the details of their potential meeting remain uncertain.
“It looks like there is a very high chance that both of the storms are going to be making landfall along the Louisiana coast,” Fox-35 meteorologist Allison Gargaro said.
Two hurricanes have never appeared in the Gulf of Mexico at the same time, according to records going back to at least 1900, said Colorado State University hurricane researcher Phil Klotzbach. The last time two tropical storms were in the Gulf together was in 1959, he said.

The last time two storms made landfall in the United States within 24 hours of each other was in 1933, Klotzbach said.
The projected tracks from the U.S. National Hurricane Center on Saturday afternoon pointed to both storms being together in the Gulf on Monday, with Marco hitting Louisiana and Laura making landfall in the same general area Wednesday. But large uncertainties remain for that time span, and forecasts have varied greatly so far for the two storms.
“Marco is going to be a few days ahead of Laura, but either way, this is going to be bringing some very strong winds and a huge impact to those communities,” Gargaro said.
Preparing for the storms
“We are in unprecedented times,” Mississippi Gov. Tate Reeves said at a news conference Saturday as he declared a state of emergency. “We are dealing with not only two potential storms in the next few hours, we are also dealing with COVID-19.”
He urged residents to prepare for the storms and, if possible, find places to evacuate that are not public shelters.
People in Louisiana headed to stores to stock up on food, water and other supplies. Raymond Monday of Gretna, though, had only a generator on his cart at Sam’s Club. “We’ve got a freezer full of food” at home, along with large containers of water, he said.
Officials in the Florida Keys declared a local state of emergency Friday and issued a mandatory evacuation order for anyone living in boats, mobile homes and in recreational vehicles and campers. Tourists who are staying in hotels in the Florida Keys should be aware of hazardous weather conditions and consider altering their plans starting on Sunday, Monroe County officials said in a news release.
The order also says all recreational vehicles must be removed from the county by noon Sunday.
In Puerto Rico, the storm knocked down trees in the island’s southern region and left more than 200,000 clients without power and more than 10,000 without water across the U.S. territory.
Officials said they were most concerned about the thousands of people in Puerto Rico who still have been living under blue tarps since 2017′s Hurricane Maria and the hundreds of families living along the island’s southern coast in homes damaged by a string of strong earthquakes this year.
