An enormous storm system sweeping toward Central and Southern California is expected to bring the second rainstorm of the fall to Long Beach.

Rain could begin as early as Thursday night, but the bulk of the precipitation is expected to arrive Friday and Saturday, with up to an inch of rain possible each day. A 50% chance of showers remains through Sunday.

A slight chance of thunderstorms will also accompany the system, potentially bringing heavy downpours.

At their peak, rainfall rates “will be mostly around a half inch per hour,” according to the National Weather Service. But, they cautioned, there is “still some uncertainty” in the Friday night and Saturday forecasts.

Winds out of the south and southwest are forecast to remain relatively tame, with gusts peaking at 20 mph.

High temperatures are expected to linger in the mid-60s through Sunday.

The city received nine-tenths of an inch of rain last month, which was about a half-inch more than average.

Long Beach has received 5.9 inches of rain this year, much lower than the 18.84 inches of rain it received by this point in 2024.
