Posted at 2:27 PM, Jan 12, 2019

Lingering showers have dissipated and for the most part, skies are mostly clear with the exception of morning valley fog. With a cold air mass in place and plenty of cloud coverage, expect temperatures to be about 10 degrees below normal through Sunday.

The Central Coast has a nice break in storms for the weekend, the focus is shifting towards next week which looks very active and wet.

Sunday night through Monday:

This storm looks similar to the rain we saw Friday night. One to two inches of rain is possible. There is a potential for roadway flooding in low-lying areas and shallow mud and debris flow near 1st-year burn scars. Isolated thunderstorms are possible, but will most likely occur over the ocean. Peak rainfall rates could reach a half-inch per hour. Gusty southeasterly winds are possible for the Central Coast with gusts up to 45 mph.

Tuesday through Thursday:

Mid-week looks to be the wettest time period with moderate to heavy rain. Early estimates indicate up to two to five inches of rain for coasts and valleys and five to eight inches for foothills and mountains. It’s unclear what peak rainfall rates will be, but shallow mud and debris flow is possible near all recent burn scars with the potential for reduced capacity in debris basins and channels. There will likely be significant travel delays and possible road closures.

There will be significant surf impacts all next week, especially at Morro Bay and Ventura harbors. High surf advisory will remain in effect for San Luis Obispo and Santa Barbara Counties until noon on Sunday with breaking waves of seven to 11 feet. There is a chance of coastal flooding and beach erosion as tides increase.

Rain will start to taper off Thursday night into Friday morning as high pressure will bring a brief scenario for southwest California.
