After the hottest and driest summer in California history and the driest September on record in Los Angeles County, there are fears that the windy season in Santa Ana does not significantly worsen what has already been a disastrous fire year. For the second time this week, Pacific Gas & Electric has had to run cutscurrent expected due to strong winds. PG&E issued the power failure warning for nearly a a dozen counties in an effort to prevent forest fires from starting. New fires are not the only concern. There are fears that high winds will stoke existing fires such as the Alisal Fire , which closed part of the 101 freeway and the Amtrak railroads in Santa Barbara County. Strong winds could not only trigger further blackouts, but also hamper the progress of firefighting. High winds in Santa Ana are expected Friday and Saturday in Los Angeles and Ventura counties said the National Weather Servedthis in Los Angeles / Oxnard Thursday . Dry, hot and windy conditions will bring dangerous fire weather conditions to the majority of Los Angeles and [Ventura] counties. br> Drought in California this summer was the worst record The Santa Ana winds are strong, hot and dusty winds that descend towards the Pacific coastue around Los Angeles from the interior desert regions. Read more Weather conditions are most common from October to March, when the desert is relatively cold. According to UCLA's Department of Atmospheric and Oceanic Sciences, winds are developing as high pressure builds up over the great Nevada Basin. What makes matters worse is that California is coming out of its worst drought ever recorded . Carol Smith, a meteorologist with the National Weather Service, says one of the risks with existing fires is that Santa Ana winds can lead to extreme fiery behavior, which includes fiery vortices and clouds. Of pyrocumulus, which can produce lightning and thunder. Fuel the humidity is very low, which means these fuels are ready. If there is a spark orsomething to start a fire, those fuels are primed and ready to take off, said Smith. Following a hot, dry summer, the lack of rain could prove disastrous. can grow 1,000 acres in an hour, so getting control as soon as possible is critical, especially in the dry, hot Santa Ana wind conditions, said Alex Tardy, the coordinating meteorologist. warnings with the NWS in San Diego. Summer 2021 was the hottest on record for mountains and deserts, putting additional stress on vegetation. Winter 2020-21 was around 40-50% of average precipitation (dry water year), which also adds to stress and drying of fuels (living or dead fuels). The hydrologic year - a 12-month period in which total precipitation is measured - runs from October 1 to September 30, and this the past water year wasn 't been kind to California. California relies on weather events called atmospheric rivers - narrow regions of the atmosphere that carry water vapor - to provide much needed water for reservoirs, lakes, and agriculture. The past year has been dismal, with just two of these strong events occurring in Southern California. The region averages seven per year. The biggest concern is what the future holds. La Nina is expected this winter , which does not generally bode well for Southern California. During a typical La Nina winter, most of the southern United States is drier and warmer. -conditions than average.This could mean that the drought-stricken southwest will likely stay drier.
