Thomas Fire almost surrounds Ojai, California

Wednesday night the fire spread further up the coast toward Carpinteria

(UPDATED at 8:24 p.m. PST December 7, 2017)

The northeast and northwest sides of the Thomas Fire continued to be very active again on Thursday. Fire authorities said 427 structures in Ventura have been destroyed and at least 85 more were damaged. Approximately 12 were destroyed in unincorporated areas of Ventura County. Ojai is becoming even more boxed in by the fire, but so far that community and Carpinteria, where the blaze is knocking on the southern boundary of the city, have avoided any large losses in the fire.

The additional area burned Thursday brings the total number of acres up to approximately 129,000 according to our estimates. At 6:30 p.m. CAL FIRE was calling it 115,000 acres.

Until the strong Santa Ana winds subside, there is not a lot that firefighters can do to stop major spread of the fire.

Strong winds Wednesday night from the east and northeast continued to push the Thomas Fire further to the west and north. It spread along the coast toward Carpinteria and as of 2 a.m. Thursday was about a mile south of Highway 150 where the road enters the city.

The fire also moved around Ojai on the north side, blazing a new path to the west two miles wide by eight miles long and crossing, again, Highway 33 northwest of the city. Ojai is now surrounded on three sides by the Thomas Fire.

The Ventura County Fire Department is calling it 96,000 acres, but we think it was least 112,000 acres when the data for the map above was collected at 10 p.m. December 6. The unofficial threshold for a fire to obtain “megafire” status is 100,000 acres… so, it qualifies.

Wednesday night a weather station at Oxnard recorded east and northeast winds of 12 to 27 mph gusting up to 32 mph.

Evacuations have been ordered for areas near Carpinteria and Ojai.

Ludicrous Fire Weather predicted in Southern California through Saturday

Above: the Red Flag Warning forecast through Friday for Alpine, California, east of San Diego.

(Originally published at 5:36 p.m. PST December 6, 2017)

In wildland fire we sometimes talk about “extreme fire weather”… strong winds with low relative humidity. But, the conditions in the forecast for Southern California Wednesday night through Saturday require a new description — Super Extreme, or Very Extreme, or, borrowing a term from Tesla vehicles, “Ludicrous” Weather?

Red Flag Warnings are posted through Saturday, with some of the strongest winds predicted for San Diego County which Wednesday night and Thursday could experience northeast winds of 25 to 35 mph, with gusts to 60 and isolated gusts to 90 mph. Oh, and relative humidity even at night will be in the low teens or single digits.

Wednesday night Ventura and Los Angeles County residents should expect northeast winds of 30 to 50 mph with gusts of 65 to 80 mph. Thursday through Saturday the winds will decrease slightly, 20 to 35 with gusts of 45 to 60 mph.

This is a very serious situation developing in Southern California — years of drought and several days of dry Santa Ana winds followed by Ludicrous Weather with winds gusting throughout the area at 80 to 90 mph. This of course could have a major effect on the existing fires. All it takes is one very small ember to be blown into receptive fuels and … well, perish the thought.

And there’s no doubt that new fires will break out. Wildland firefighting resources are stretched thin covering the 80,000 acres already on fire. It will be difficult to find hundreds or thousands of additional firefighters and large numbers of hand crews and engines if the worst case scenario develops. And the stronger the winds are, the less effective aerial resources can be. Those conditions can make it unsafe to fly low and slow over rough terrain, as they have to do, and the wind can blow the retardant or water far off target.

Ludicrous Fire Weather begins tonight!

30 homes reported destroyed in the Creek Fire

The Creek Fire has burned 11,337 acres in Los Angeles. The nearby Rye Fire in Santa Clarita was mapped at 7,000 acres.

Map showing heat detected by a satellite on the Creek and Rye Fires in the Los Angeles Area. The red dots are the most recent, detected at 12:40 a.m. PST December 6, 2017. It is likely that some areas with light vegetation burned and then cooled before the heat sensors on the satellite detected them on the subsequent pass, and therefore do not show up.

The Creek Fire on both sides of the 210 freeway in Los Angeles has burned 11,377 acres and destroyed 30 homes. Three firefighters have been injured and 30 horses were killed.

Both sides of the 210 freeway near Sylmar that had been closed, reopened Wednesday morning. The fire started early Tuesday morning in the Kagel Canyon area.

Another fire in the same general area has burned 7,000 acres. The Rye Fire was reported Tuesday morning in Santa Clarita near Castaic Junction, the intersection of Interstate 5 and Highway 126. Officials are considering lifting some of the mandatory evacuation orders. About 775 firefighters are on scene.

The 405 opens after being closed by the Skirball Fire in Los Angeles

The 405 freeway has reopened after being closed by the Skirball fire across the freeway from the Getty Center. Los Angeles Fire Department reported Wednesday afternoon that the fire has burned 475 acres and damaged at least eleven homes and destroyed four. Fire officials said 700 homes were evacuated near the Sepulveda Pass.

(Originally published at 8 a.m. PST December 6, 2017.)

A wildfire that started early Wednesday morning near the Getty Center and Sepulveda Pass has forced the closure of all lanes of the 405 freeway in Los Angeles, one of the busiest highways in the state.

The Skirball fire was reported at 4:50 a.m. and was more than an acre when the first units arrived. Live video from Los Angeles television stations have shown at least two homes with flames on the roofs near Casiano Road. Mandatory evacuations are in effect for the area.

North winds of 8 to 14 mph and a relative humidity in the low 20’s caused the fire to spread rapidly to the south.

At about 7 a.m. the reported size of the fire was 50 acres, but it may have grown significantly since then. Helicopters, scooping air tankers, and about 220 firefighters were working the fire Wednesday morning.

Thomas Fire burns to the ocean

The fire has burned at least 65,000 acres in Ventura County.

(UPDATED at 10:20 p.m. PST December 6, 2017)

The Thomas Fire north of Ventura, California continued to grow on the northeast side, east of Ojai on Wednesday. The Ventura County Fire Department reported Wednesday evening that the fire has now burned 90,000 acres.


(Originally published at 6:36 p.m. PST December 6, 2017)

After burning into Ventura, California on Monday the Thomas Fire continued to grow, pushed by very strong Santa Ana Winds usually out of the northeast. On Tuesday the winds were not quite as strong but the problem for firefighters was the variable direction. Beginning at 11 a.m. winds out of the east and south spread the fire across Highway 33, the route from Ventura to Ojai, through oil fields and over a ridge until it reached and in some places crossed, Highway 101 northwest of Ventura where it reached the beach in some places. Helicopters dropped water on the fire overnight near Foothill Road and at Solimar Beach.

The Thomas Fire is now well north of Highway 150, east and northeast of the city of Ojai.

Firefighters have not had time to accurately tally how many structures have been destroyed — the latest estimate is 150 including the Vista Del Mar Hospital —  but the number may be significantly larger when the smoke clears.

On Tuesday fire officials reported the fire had burned 55,000 acres. Wednesday morning a spokesperson for the Ventura County Fire Department said it had increased to 65,000 acres.

Over 1,000 personnel are fighting the blaze. At least 27,000 residents were ordered to evacuate Tuesday, but that number grew when the fire crossed Highway 33 and threatened the coastal areas.

The wind has made it difficult to use firefighting aircraft, but the forecast for the mountains northeast of Ventura on Wednesday includes 10 to 14 mph northeast winds gusting at 16 to 21. This may make the use of the 30 air tankers that will be in California Wednesday, possible. The forecast also predicts 74 degrees and 9 percent relative humidity, which are weather conditions conducive to significant fire spread.
