Los Angeles Fire Detection and Evacuation During the Break-Out of Tuesday‘s Eleven-Day CALIFORNIA Winds

Much of Ventura Co. and West LA Co. will be affected by strong winds through Wednesday. Critical fire weather is expected, so PLEASE have multiple ways of getting notifications in case of new fires & prepare ahead of time,” the NWS Los Angeles office wrote in a post on X.

Currently the number of people under evacuation orders has dropped to about 92,000, with 89,000 people under evacuation warnings, Los Angeles County Sheriff Robert Luna said Monday. As winds return next week, new warnings and orders are likely to be issued.

They put a Particularly dangerous situation warning in place from 4 a.m. Tuesday through noon Wednesday, as they worried that strong winds would start fires and even cause new ones. But by early Tuesday afternoon, the winds were proving to be less strong than expected, and the Weather Service dropped the warning for the rest of the day. There will be another dangerous situation warning from 3 a.m. to 3 p.m. Wednesday.

Mr. Clark was most concerned about the forecast for the Santa Ana winds as they are expected to pick up again Tuesday night into Wednesday.

Robert Clark, a fire behavior analyst for Cal Fire who is working on the Palisades fire, was relieved Tuesday’s winds weren’t as powerful. The fire didn’t grow overnight, and quieter weather was allowing crews to extinguish fire in pockets of smoldering landscape and vegetation.

The designation of a particularly dangerous situation is new, according to Mr. Kittell. The office decided to use the stronger warning because of the ongoing fires, even though Tuesday’s forecast was always right between high level and not.

The forecaster in Los Angeles likened it to someone filling out an N.C.A.A. brackets. Even if you’re the best, you won’t have a forecast verify at some point.

James Brotherton, a meteorologist with the Weather Service in Los Angeles, said he would much rather have a forecast be wrong if it meant there was “less pain and suffering.”

Sometimes, a storm will overperform the forecast, and sometimes it will under perform. In meteorology, both eventualities are considered to bebusted forecasts. While forecasters who predict an especially extreme event might be happy if the conditions aren’t as bad as they had predicted, they know that if the forecast is off by too much, people will trust future warnings a little less.
