#CAwx #NVwx #CAfire /ljvMWRy4ws- Daniel Swain September 9, 2022Īs if all of that were not enough, Tropical Storm (and former hurricane) Kay made a historically close approach to Southern California at the same time huge fires were burning up north. This one is going to be burning & producing large volumes of smoke for many days, so folks in NorCal and western Nevada should prepare for a potentially prolonged period of smoke-related air quality impacts. The Mosquito Fire is, today, still marching steadily upslope amid record dry vegetation conditions.Įxtraordinary images of #MosquitoFire this evening. This fire, which has also destroyed dozens of structures, experienced a period of exceptionally intense fire behavior at the peak of the heatwave–generating an extremely large pyrocumluonimbus cloud that likely generated multiple fire vortices and injected smoke into the stratosphere. Then, on the western slopes of the Sierra Nevada, the Mosquito Fire ignited near Foresthill–rapidly becoming the largest fire in California to date this season. Multiple large (and even deadly) fires blew up in Southern California in NorCal, the also deadly Mill Fire consumed an entire neighborhood in Weed, CA. In the midst of this extreme heat, as well as ongoing severe drought, wildfire activity in both northern and southern California escalated dramatically. California’s power grid was pushed to the brink–logging an all-time record for statewide power consumption, but although there were some regional power outages rolling blackouts were narrowly avoided thanks to successful demand response actions (that is, people and commercial power users temporarily and voluntarily conserving for a few peak hours each day). Many other locations set records for the greatest cumulative/consecutive number of 100 degree days (Sacramento set a similar record for consecutive 110F degree days). This includes the state capitol of Sacramento, as well as portions of the northern and eastern San Francisco Bay Area (Santa Rosa and Livermore) and the Mendocino County interior (Ukiah), where temperatures reached a truly extraordinary 115F to 118F. Countless cities from northern Mexico to western Canada broke long-standing September monthly temperature records–some on multiple days–and some locations in northern California experienced their singularly hottest days on record…period. ![]() In Southern California, this was an unbearably humid heatwave in Northern California, this was a much drier but even hotter event. ![]() To start the month, the most severe September heatwave on record in the Western United States (and the worst heatwave in any calendar month, in some places) roasted California and adjacent states for 7-10 days. Well, it sure has been a September to remember in California, weather-wise. The first two weeks of September 2022 were the hottest such weeks on record across most of the Western United States. 0 Comments A record-shattering September heat event…and a tropical storm.
