Peak shocks at a maximum speed of 100 km / h


From the Tahoe Basin to Los Angeles County, great heat hissed in California on Thanksgiving Day.

The blust conditions are the result of an upper-level trough that sinks south into the Great Basin, said Scott Rowe, a forecaster for the National Meteorological Service.

In Tahoe, wind speeds are increasing 90-100 mph tilted mountain peaks and Lake Tahoe saw isolated gusts of wind up to 30 km / h.

At the top of the hill, a weather meter for Kirkwood’s ski lift recorded a speed of 160 km / h. Rowe explained that this anemometer was in a heavily exposed location and not representative of what people experience on the ground.

“I heard chair 6 is at the top of a peak, at the top of the elevator … as high as it can be,” Rowe said. “Some of these stations are extremely exposed beyond the meteorologically normal locations. They are not representative of the near-surface environment.”

In the Sacramento Valley, wind control advice was in place from Thursday to 5 p.m., with gusts of up to 35 mph. The weather service warned of fallen tree limbs, loose objects and blowing festive directions.

These northern edges, which whip up the state on Thursday on Thursday, are common in the fall and are called Diablo in Northern California and Santa Ana in Southern California. The sea wind blows hot air from the land areas towards the shore and is known to dehydrate the landscape and essentially suck out the moisture of the vegetation, making it dry and exposed to burns. The risk of wildfire can be high in these wind episodes.

In the Gulf area, the incident ranged from moderate to weak, but the weather service continued to warn of the danger of fire.

“It should be noted that the November / December fires are not entirely unheard of – the Pfeiffer fire in Big Sur and the McCabe fire are all in 2013,” the Bay Area weather service noted in its Thursday forecast.

Gusts of 55-65 km / h over the peaks over the North Gulf and East Bay were recorded Thursday morning. Weaker winds blew through valley areas at speeds of up to 30 mph at San Francisco International Airport.

In Southern California, the situation was more severe than in the north, where on Thursday morning winds roared above 60 km / h on hills where there had been little rain since last winter.

Edison, Southern California, had previously turned off power to nearly 5,000 customers, mostly in Ventura County, to reduce the risk of pipelines causing dropped or damaged power lines.

The utility is considering shutting down another tens of thousands in Kern, Los Angeles, Orange, Riverside and San Bernardino counties, as well as additional customers in Ventura.

Early Thursday morning, the wind blew at 62 mph in the San Gabriel Mountains, and peak speeds are not expected until Thursday night until Thursday night.

Humidity levels are forecast to drop to 10-25% on Thursday and some local points on Friday could drop to single digits.

The weather service extended the red flag warning for Los Angeles and Ventura County Mountains in effect until Thursday night. In southern California, gloomy weather is expected to calm down Friday night and Saturday, but the weather service has warned of “very dry” conditions.

In recent weeks, a handful of storms have passed over California, delivering healthy amounts of rain to more remote areas of Northern California and accumulating snow in the northern Sierra Nevada. But the systems did not bring the widespread rain that the state desperately needs to soothe the landscape and curb the risk of wildfire.

“In the wettest places, this rainfall can be seen as‘ ending the fire season ’- and elsewhere the rains have significantly mitigated the risk of wildfire,” wrote Daniel Swain, a Los Angeles UC climate correspondent on the Weather West blog. “But the real season-closing rains still haven’t arrived in some parts of NorCal, and certainly not in much of SoCal yet.”

Swain noted that the fall of 2020 is well on its way to being among the top five driest in much of California.


“This follows immediately after the highest August-October period in California,” Swain wrote.

In short, the wildfire season is not over yet.
