Southern California's wild weather swings continue. Next up, rain

Southern California is likely in for a solid dose of rain this week, just days after heat and Santa Ana winds helped fuel several wildfires across the region.

Forecasters expect the bulk of the rain to roll into the Los Angeles basin Wednesday night and continue into Thursday morning, with a small chance of thunderstorms and hail.

The San Fernando Valley, San Gabriel Valley and coastal areas across L.A. and Orange counties could get around an inch over the next few days. Hills and mountains could get up to 3 inches.

“We could see some pretty high rain rates,” said National Weather Service meteorologist Mike Wofford. “It's a good storm for this time of year — it's a little stronger than what we would see normally.”

The possibility of significant rain in the mountains raises concerns about flooding in areas recently burned in wildfires, particularly around the Bryson Fire burn scar near Malibu, which is only a few days old. Burn scars can’t absorb heavy rainfall and are susceptible to landslides.

The National Weather Service has issued a flood watch for the Santa Monica Mountains and surrounding communities from Wednesday afternoon through Thursday. That means heavy rain there could flood streets, creeks and rivers. The flood watch area includes both the Bryson Fire and Palisades Fire burn scars.

This will also be the first nontropical storm of the season, meaning it’s moving into the region from the north. Most storms that hit Southern California follow a similar path, especially during the winter, unlike the tropical storms that formed off the coast of Mexico and brought muggy weather to the region this summer.

Nontropical storms also bring cold air to the region. On Wednesday and Thursday, forecasters expect highs in the 60s and 70s. High elevations will be even cooler.
