A “winter-like” storm will sweep across Southern California late Monday into Wednesday, bringing the chance of “significant” rainfall, the National Weather Service said Sunday.
Most of the rain is expected to occur Monday night through Tuesday afternoon, potentially creating a headache for commuters.
Rainfall totals during that time could range from three-quarters of an inch to 1½ inches, said Richard Thompson, meteorologist for the weather service. Mountain and foothill areas could see up to 3½ inches of rain.
Rainfall rates could be half an inch or more per hour, leading the weather service to put burn areas on flood watch from Monday night to Tuesday afternoon, he said.
There’s also a chance of thunderstorms and strong and gusty winds.
Though it is early in the season, it’s not unheard of to get a storm or two in October, Thompson said.
“Usually our Octobers are dry,” he said, “but we do get storms from time to time.”
The early-season-storm forecast coincides with the official return of La Niña, a climate pattern usually responsible for driving drought in Southern California.
The reemergence of the ocean phenomenon — after last year’s rainfall was below average — could mean another drier-than-average winter, further worsening fire conditions in the region.
