Thanksgiving in Los Angeles kicks off with severe wind warnings

Downed trees and possible power outages. Thanksgiving in parts of Los Angeles and Ventura counties kicked off with a red flag warning and hot, dry gusts of Santa Ana winds that are expected to peak Thursday afternoon and ease Friday morning.

A severe wind advisory is in effect until 3 p.m. for the San Fernando Valley, Santa Clarita Valley, Ventura Valleys, as well as the Santa Monica Mountains and Los Angeles County. Winds are expected to blow up to 60 to 75 mph in more mountainous areas, with a particularly windy hotspot between Santa Clarita and Burbank — known as the Magic Mountain Truck Trail — already hitting 91 mph as of 8 a.m. Thursday.

Wind conditions, even after peaking, are expected to remain fairly strong until 11 a.m. Friday. Weather officials have advised fire-prone communities to remain vigilant.

“The fire danger will exist through tomorrow,” said Ryan Kittell, a meteorologist with the National Weather Service in Oxnard. “While the winds will peak today and gradually decrease through tomorrow, they will still be windy enough through tomorrow morning – and the air will still be dry enough to cause this increased fire risk.”

These winds mark the third Santa Ana event in a week after powerful gusts overturned semi-trucks, damaged electrical equipment and started a fire at a Fontana pallet park.

As a precaution, approximately 5,000 Southern California Edison customers in high alert areas – including southern Ventura County, a northwest swath of Los Angeles County and an area along the 215 corridor in Riverside County – could lose power Thursday depending on wind strength. , according to spokesman David Song.

Song said the “period of concern” for high winds should ease by 6 p.m. and utility officials hoped they wouldn’t have to proactively turn off anyone’s power on Thanksgiving Day.

The Santa Ana Winds, the infamous and often devastating gales that mark a quintessentially Californian season, tend to wreak havoc each fall when a high-pressure cold-air dome develops over Nevada and the Midwest region. Big pool. This high pressure forces the air to spread in all directions, including over the mountains and into Southern California.

Rather than a coastal breeze blowing from the ocean to land, the wind conditions in Los Angeles are reversed during these high pressure events: Santa Anas blows very fast and superheated, rolling down mountain slopes, lifting foothills and chopping down trees as they head out to sea.

Due to this shift, the temperatures typical of the various microclimates of Southern California are also reversed. Beach towns along the Los Angeles and Ventura coasts are expected to experience warmer, sunnier weather on Thursday and Friday, with temperatures between the mid-70s and below 80. Mountains and deserts, on the other hand, will remain cooler and in the mid 60’s.

Temperatures are expected to cool across the region by Saturday, with temperatures in the mid-60s to below 70s. There’s also a chance of light rain on Monday and Tuesday, but officials said models meteorological conditions were still too far away to determine a more precise forecast.
