Update: Now Post-Tropical Storm Rachel has made landfall along northern Baja CA north of Ensenada. San Diego is thus spared brunt, but bands of torrential rainfall & severe thunderstorms are occurring from CA's Imperial Valley eastward into AZ, w/serious flash flood threat. #CAwx

#ChadCrilley #CAwx From Meteorologist Chad Crilley on FB: 2:00 PM: As expected strong to severe thunderstorms are developing to our north across San Bernadino County. There will be a brief window for a severe storm or two across Imperial County this evening as forcing from low pressure combines with tropical moisture. The most likely time for a severe storm will be from 4 PM - 9 PM. The primary concern is for wind gusts to 60 mph and some quarter-sized hail. I am watching this set up closely. @uccawx@m.ai6yr.org @ai6yr@m.ai6yr.org#Imperialcountywx #Brawley #ElCentro #Mexicali #Yuma

LA Times: The surprising reason California survived record summer heat without blackouts "...In fact, the state has not issued a Flex Alert since 2022, and it has not implemented rotating outages since 2020. Over the last few years, California has quietly but dramatically increased the resiliency of its electrical grid through a significant expansion in battery energy storage. These batteries hold onto solar energy captured during the day, so it can be sent to the grid as demand peaks in the evening and morning, when most people are at home running air conditioners and other appliances. ..."

LOL two snake calls at the same time at a condo complex... apparently they're tired of the heat, too, probably looking for the pool. #scanner #VenturaCounty #heatwave #CAwx

(Regulars, go back to sleep and Ignore me, up early playing airport shuttle driver) Was still 82F at 1am, now down to 79.2F (but 55% humidity) at almost 3am. Air conditioning has been running constantly. Not sure how the folks without A/C are handling this heatwave, aside from self basting in their homes. #heatwave #CAwx #VenturaCounty

At last, a clearer forecast re: California and Marie! Marie is now weakening and will stay well offshore. However, confidence has increased that Marie's remnants will actually have a substantial influence on CA weather for the next 5-6 days! [Thread] #CAwx

In case you missed it live, Tuesday's #ElNiño-focused virtual town hall event hosted by CA Sen Mike McGuire was recorded and is now available. This was a really constructive and worthwhile event; I'd strongly encourage folks to check it out! #CAwx
