Worth noting we will likely see a second episode of high winds near the coast tomorrow as our second low deepens offshore (possibly sub 980 mb) before lifting inland on Friday. 12/23/2025

Peak wind gusts in the 50-60 mph range mainly along the mountains and near the coast including Half Moon Bay up to 52 mph. Close to where most of the outages are popping up. Max wind speeds still expected near midnight-2am as low pressure moves north up the coast 12/23/2025

Still early but as of the 9pm hour per PG&E storm related outages are increasing esp. Santa Cruz mtns and coastal areas. Peak wind expected near/just after midnight. Similar round of wind expected again tomorrow night as well @nbcbayarea 12/23/2025

The other elephant in the room is severe weather potential the next two days, which looks favorable for severe t-storm potential for much of coastal California as noted by SPC. Damaging wind, waterspouts/brief tornadoes inland will be a possibility. Stay tuned 12/23/2025

Wind may lead to larger weather impacts tonight esp. near the coast & coastal mtns where tree and power impacts overnight. Rain at times (with breaks) plus the potential for strong t-storms will be possible Wednesday into Thursday. Stay tuned. @nbcbayarea 12/23/2025 #CAwx

Mt Tam and other North Bay mountain sites well over 4" inches and still climbing as of 8pm. Rain totals for the Central Bay and Santa Cruz mtns will see rises overnight as rain slowly dips south into the morning commute. #CAwx 12/21/2025

North Bay & Santa Cruz mountains forced lift taking advantage of the high precipitable water values rain totals through 6pm. Peninsula, East Bay and South Bay locations should see totals climb as rain shifts south overnight. Rain heads north later tomorrow and increases again w/ late Tue wind/rain
