First there was scorching heat, then there was sticky, uncomfortable humidity. Now forecasters say it’s time to pull out the umbrellas because rain is headed to Southern California.

A low-pressure system off Baja California will bring slightly cooler temperatures, showers and possible thunderstorms to Southern California on Wednesday and Thursday, said meteorologist Rich Thompson of the National Weather Service.

But there are no guarantees all areas will receive large amounts of rainfall.

“Some areas could get a good amount of rain,” he said. “Some areas could get a trace amount of precipitation.”

Showers could begin blanketing parts of Southern California on Wednesday afternoon, but most of the rainfall is expected Thursday. Temperatures will remain in the 80s.

Thompson said one thing is certain: “Everywhere in L.A. County has a good shot to get rain.”

According to the weather service, showers will be widespread over San Bernardino County.

Showers and thunderstorms over the mountains could bring downpours, increasing the possibility of flash flooding and debris flows Thursday, forecasters said.

This week’s rain is typical for October when Southern California usually gets a storm or two, Thompson said. It’s definitely not El Niño-related, he added.

“This is nothing out of the ordinary,” he said.
