Parts of the Central Coast saw some precipitation overnight and a few light showers look to continue with increasing cloud cover early Saturday morning across northern parts of San Luis Obispo County.

The next stronger storm system will move into the area Sunday night into Monday along with snow accumulations possible above 5000 ft and locally heavy showers at times.

Many areas only saw trace amounts of rain, but places like Cal Poly saw nearly 0.10 of an inch of rain since midnight.

These low clouds are expected to gradually dissipate through the morning hours for northern parts, partly sunny skies are expected for southern San Luis Obispo County and Santa Barbara County.

There are also a couple of advisories to watch on the Central Coast.

A High Surf Advisory went into effect Saturday at 9 a.m. expiring Tuesday at 3 p.m. for west and NW facing beaches in SLO/SB Counties. This means large breaking waves 8 to 12 ft are possible with local sets up to 15ft as well as dangerous rip currents.

A Winter Storm Watch is issued for late Sunday night through Monday for the Santa Barbara County mountains including San Marcos Pass. Heavy snow 6 to 10 inches with gusty SW winds 15 to 25 MPH are possible in higher elevations above 5000 ft. Gusts could reach up to 40 MPH.

Temps will be cooler today with daytime highs at the beach reaching the upper 50's, low 60's for the coastal valleys and interiors.

A surface cold front will push into the Central Coast with rain likely by late Sun evening, then sweep thru the rest of the area overnight.

Meanwhile, a secondary front looks to develop in SLO/SBA Counties with another surge of rainfall later Sun night into Mon morning. We are watching for a Flash Flood Watch for this system as it could impact recent burn scar areas, but none have been issued yet for the first significant storm of the season.
