From the perspective of being in Mt. 

Shasta city it hasn't changed much from what you see here. I can see the mountain from the city but sort of barely
at this point. The smoke isn't burning my nose and nostrils like it has in other fires because mostly the smoke is 
rising into the sky and not moving along the ground as much. But, every so often pieces of ash are falling.
Everitt Memorial Highway up the mountain from Mt. Shasta city is closed in order to keep people from dying 
in the fire or succumbing to smoke inhalation at altitude who are not used to both smoke and altitude at the same 
time. My wife got smoke inhalation at Lake Tahoe about 20 years ago and had to spend the night in the hospital
there on oxygen because she just tried to unload the car at 6000 feet in the smoke from a fire even though I 
told her not to because I lived in Mt. Shasta during fires before and I knew you can't be active much during 
heavy smoke times at altitude unless you are really young and in perfect health like a firefighter. I don't see the 
helicopters as much today as yesterday because it is harder to see for everyone because of smoke so flying would be more dangerous
because you cannot see through heavy smoke. The other problem firefighters are dealing with is that
beyond the altitude and the smoke they are dealing with 92 to 96 degrees here in the city of Mt. Shasta
and in Weed, Californiia nearer the fire it is presently 93 going to 98 degrees. So, the fire and the day
is really hot to fight a fire.

The white lines on the map were the perimeters of the Lava & Tennant Fires at about 11:30 p.m. PDT June 30, 2021. The red dots represent heat detected by a satellite at 2 a.m. PDT July 1, 2021.

Lava Fire
The Lava Fire was most active Wednesday on the east side, north of Mt. Shasta, where beginning at 4:30 p.m. it spread to the east for more than a mile. It chewed up another 2,000 acres to bring the size up to 19,680 acres.

Firefighters conducted burning operations Tuesday night on the west side, south of Highway 97. On Wednesday they made progress on the southwest side with the heavy use of hand crews, dozers, helicopters, and air tankers.

Resources assigned to the fire Wednesday evening included 26 hand crews, 86 fire engines, and 13 helicopters for a total of 1,273 personnel. Air tankers are used as needed and available, but are not assigned to any one fire.

No information has been released about the number of structures destroyed.

Evacuation orders are in effect; details for the Lava and Tennant Fires are at  https://arcg.is/1CrfH40.

Tennant Fire
The Tennant Fire, 15 miles northeast of the Lava Fire, was active on both the east and west sides on Wednesday, spreading for about 0.4 of a mile on both sides. It has burned on both sides of Highway 97 and as of 11:30 p.m. on Wednesday had blackened 9,439 acres, an increase of about 1,300 acres over 24 hours.

The Incident Management Team reported that five structures have been destroyed.

Wednesday evening there were 278 personnel assigned to the Tenant Fire, including 7 hand crews, 14 engines, 5 dozers, 13 helicopters, and 50 overhead personnel. Air tankers are used as needed, but are not assigned to any one fire.

Weather
The weather forecast for Thursday calls for sunny skies, almost no chance of rain, 91 degrees, 15 percent relative humidity, and in the mid-afternoon 15 mph winds out of the south gusting to 23 mph. This could, again, lead to active fire behavior after 1 p.m. The outlook for Friday is about the same.

Lava Fire
The Lava Fire about two miles east of Weed, California was very active late in the afternoon Tuesday, putting up a large convection column of smoke topped by a pyrocumulus cloud. There was some growth to the north into Juniper Flats near Highway A12, but the majority of the movement was to the south and east in timber stands on the west and north slopes of Mt. Shasta. Spotting from torching trees created spot fires up to 0.75 mile out.

It was mapped Tuesday night at 17,591 acres.

The fire is burning through brush and timber which is interrupted by numerous patches of lava rock left over from many volcanic eruptions over the last 593,000 years. The fire is driven by very dry vegetation, spot fires, and occasional gusty winds.

The U.S. Forest Service fire organization has entered into unified command, with CAL FIRE assuming the north branch containing the most community protection.

Approximately 3,200 residents have been evacuated in the community of Lake Shastina.

Crews initially attacked the fire when it was small, then left

The San Francisco Chronicle reported that in a town hall meeting Monday night the Forest Fire Management Officer (FMO) of the Shasta-Trinity National Forest said fire crews initially attacked the Lava Fire Friday afternoon when it was 1/4 acre.

Shasta-Trinity National Forest spokesperson Adrienne Freeman said the crews, thinking it was safe, left at 4 p.m. with plans to watch it from afar and return Saturday morning. However an hour later it flared up and spread rapidly.

“I apologize for that getting out”, the FMO said in the town hall meeting. “I’ll take the heat for that … I will own that … They got in with an initial attack and they got beat. It happens sometimes and is not the intended outcome, not what we want. We’re all disappointed that this happened, but it happened.”

Tennant Fire
The Tennant Fire first reported at 4 p.m. June 28 is 16 miles northeast of the Lava Fire on both sides of Highway 97 near Tennant Road. It is mostly on land protected by the Forest Service but is also on private property protected by CAL FIRE. The Forest Service reported Wednesday morning that it was mapped at 8,159 acres. It was very active Tuesday.

California Interagency Incident Management Team 15 will assume command of the Tennant Fire Wednesday.

Evacuation orders are in effect; details for both fires are at  https://arcg.is/1CrfH40.

Weather

The weather forecast for Wednesday calls for 98 degrees, relative humidity in the low teens, and in mid-afternoon 14 mph winds out of the south gusting to 21 mph. This could result in fire behavior similar to what was seen Tuesday. A red flag warning is in effect Wednesday for Southern Oregon 17 miles north of the Tennant Fire.

The outlook for Thursday is about the same, but the wind will be from variable directions at 2 to 7 mph.
