Editor's note: This story has been updated to add 12-hour rain totals below.

More rain is falling in San Luis Obispo County on Friday morning after overnight showers dropped between 0.5 and 1.5 inches of rain on San Luis Obispo County.

The National Weather Service issued a flood advisory, saying periods of heavy rain are expected later Friday morning. There is also a chance of thunderstorms, which could produce higher rainfall rates. The rain is expected to cause water to pool in roadways, especially in low-lying areas and intersections. Rocks and boulders could also fall onto roadways.

Southerly winds of 20 to 30 mph with gusts up to 40 mph are expected to continue into the evening, according to the NWS. Isolated gusts up to 55 mph are possible near the coast and higher elevations. The winds could make driving difficult, especially for those in high-profile vehicles.

High surf, high tides, gusty winds and rainfall runoff through creeks could also produce a flooding threat in low-lying coastal areas Saturday morning, according to the NWS. Most threatened are the coastal campgrounds and parking lots between Pismo Beach and Oceano.

This week's storms are bringing much-needed rain to parched California. A storm Wednesday night dropped between 0.24 and 2.13 inches of rain on the Central Coast.
