For the 1st time in 25 years not a single square mile of California is dry on the US Drought Monitor. Have to go back to December 2000 to find a similar situation. If you're 25 or younger you've always lived in a world where California has been entering or recovering from drought

🚨🚨 [8:30 PM] The showers and thunderstorms we've seen over the past few hours were only the opening act, don't let your guard down. The main show comes later tonight into early Christmas morning. Only Santa is immune to weather conditions. Keep your electronics charged! #CAwx

Hurricane season officially ends today, and for the first time since 2015, not a single hurricane made landfall in the US. Finally, a quiet season.

It hasn’t been this hot this late in 35 years. Seattle’s high of 91 degrees today is the city’s latest 90-degree reading in the calendar year since Sept. 22, 1990.

We hit 84° today in San Francisco making it the hottest day of 2025 and also the hottest day in nearly a year. Hot weather continues tomorrow.

Fire Weather Update: hot and dry conditions from Mon-Wed will be followed by a chance for dry lightning Thu-Fri. #CAwx

(2/2) You may have also noticed muggier conditions today. This is due to multiple variables such as warmer sea surface temps, the incoming moisture and seasonal daytime heating. These conditions will persist the next few days. Heres a look at current dew point readings:
