After a relatively dry start to 2024, the storm door could swing open soon for Southern California, where back-to-back rainstorms are expected this week, according to the National Weather Service.

A storm front is expected to approach northwest San Luis Obispo County late Tuesday night, bringing about a 60% chance of rain to the region around Wednesday morning, according to the weather service. There is a 40% chance that light rain will spread across San Luis Obispo and northern and western Santa Barbara County by Wednesday morning.

The storm is projected to drop up to a tenth of an inch of rain in all but the northwestern coastal portions of San Luis Obispo County, which could see up to a quarter of an inch. Temperatures are expected to lower by 3 to 6 degrees, with coastal locations to see temperatures in the lower to mid 60s. The strongest winds will be felt across the Los Angeles mountains and the Antelope Valley.

Southwest-facing slopes are expected to see between 2 to 4 inches of precipitation and northwest San Luis Obispo County 5 or more inches.

Sunday will have the highest chance of heavy rain. Los Angeles is expected to receive at least 1.2 inches of rain between Friday evening and Monday.
