Topline:

Southern California is experiencing a “remarkably dry” start to the winter, according to the National Weather Service. Our wet season typically starts in December, but most of Southern California has seen no rain for a record 255 days, and there’s no end to that dry streak through at least the rest of this month.

What it means: Weather authorities are calling the ongoing high fire risk and dryness of vegetation “extraordinary for January.” This winter is now the driest, or second-driest, on record for most of Southern California.

The context: Fossil fuel pollution in our atmosphere is supercharging Southern California’s natural weather cycles, driving what’s called “weather whiplash.” Two years of historically wet winters allowed lots of vegetation growth, then a record hot summer dried it all out. UCLA researchers found vegetation was about 25% drier than normal this January due to human-caused climate change. Add in extremely strong Santa Ana winds and it’s a recipe for the deadly and destructive disaster that has unfolded.

What’s next: Weather officials are predicting little to no rain through at least the end of the month. They’re also predicting a possible new round of Santa Ana winds next week. Once rain does come, with the recent fires, there’s an increased danger of mudslides.

Be prepared: Pay attention to weather alerts and local news, keep that go-bag packed and have a plan to evacuate. We know this is a difficult time for our communities, so make sure you also are getting the mental health support you need during these times of extended stress and danger.

The future: Scientists warn that if fossil fuel pollution isn’t significantly cut, these kinds of extreme events are only predicted to worsen.
