This week, California is preparing for harmful winds



Strong winds began in parts of Northern and Central California on Sunday night and are expected to continue until Wednesday.

Strong wind signals are in effect for more than 30 million people from northern central California to southern California.

A strong high-pressure zone will be built across the northwest on Monday, and this high-pressure zone will move to the Great Basin by Tuesday. While this high-pressure zone is being built, a low-pressure zone will develop along the southern coast of California.

The proximity and strength of the two systems is important. This is known as the pressure gradient, which is expected to be quite strong and will lead to the development of these intense winds earlier this week.

The wind blows from high pressure areas to low pressure areas, so in this case the winds for this event are expected to be offshore winds when the wind moves from land to sea. Locally, in different parts of California, these wind events are often referred to as “Diablo Winds,”

; “Mono Winds,” or “Santa Ana Winds.”

Time

Areas of Northern and Central California are already experiencing these strong winds, which will continue until Tuesday.

“Gusts in populated areas can reach a range of 30 miles per hour, while in hills and mountains, gusts up to 40 and a possible range of 50 miles per hour. Prepare now,” the San Francisco National Weather Service said Saturday night. .

The strongest winds in Northern and Central California are expected to develop on Monday night against Tuesday morning.

“We are more confident that widespread persistent westerly winds of 35 to 55 miles per hour will be possible with gusts of 70 to 80 miles per hour, strongest from below and through passages and canyons,” the NWS Los Angeles office said. Angelis on Saturday afternoon.

The strongest winds in Southern California are expected on Tuesday.

This strong wind can cause downed trees and power lines, power outages and potentially widespread critical weather conditions in much of the state.

Fire weather

Typical fire conditions in Southern California are fueled by a combination of above-average temperatures, low humidity, dry vegetation, and strong winds. The evolving low pressure off the coast of Southern California may limit some of these factors, bringing with it lower temperatures and higher humidity values. Therefore, fire conditions may be slightly limited earlier this week.

However, many places in Southern California, including Los Angeles, have not seen measurable rain since late December, meaning the vegetation in the region has had more than two weeks to dry.

Southern California has also experienced record heat over the past few days, in addition to the growing drought in the region.

When you consider dry vegetation, drought conditions and strong winds, only one spark is needed for the fire to start and spread quickly. The Storm Forecast Center does not rule out the possibility of critical fire weather, especially on Monday.

“Confidence in the wind forecast remains quite high, but the colder air entering the region will start a cooling trend that will improve relative humidity (RH) values ​​over the forecast period,” the Storm Forecast Center said on Sunday. in the morning.

The SPC also said that these humidity levels could fall on teens in some places due to declining winds – dry winds that run from east to west through California’s mountain passes – which could lead to several hours of critical fire. Monday afternoon.

However, this low-pressure area will bring much-needed rain and snow to parts of the Southwest over the next few days, helping to reduce widespread drought conditions in the region.
