A second impulse of the storm extends concern of flooding and hazardous conditions into Tuesday

A flood warning has expired for Santa Barbara County, SLO County, Ventura County. However, conditions remain hazardous. Do not travel unless necessary. Monday's first round of rainfall resulted in severe and widespread roadway flooding. If you encounter flooding, turn around and never drive or walk through it.

A flood watch is in effect for San Luis Obispo County until 11:00 am Tuesday, in Santa Barbara County until 11:00 am Tuesday, and in Ventura County until 1:00 pm Tuesday. Rainfall rates will be mostly around one half inch per hour, but could peak for short periods around one inch per hour.

In addition to flooding, Monday's front caused several other issues with debris, rock falls, and mudslides. There is continued concern of debris flow around the Alisal, Thomas, and Cave fire burn scars. Be wary of full or overflowing streams and rivers, and low-lying flood-prone areas.

There is a river flood warning until 11:00 am Wednesday for the Santa Ynez River near the narrows. All other river flood warnings have been allowed to expire.

Coasts and valleys have already received 3 to ​7 inches, whereas mountains and foothills have received 6 to 12 inches with some localized areas up to 16 inches. We are expecting a half inch to inch additional rainfall today for coastal areas, 1 to 2 inches extra for mountains and foothills, and locally up to 3 more inches.

Wind warnings and advisories have been allowed to expire for all areas. Wind will taper off through the day.

A high surf advisory is in effect for the Central Coast, South Coast, and Ventura coast until 10:00 pm Wednesday. Breaking waves will be 10 to 15 feet, 4 to 7 feet, and 6 to 9 feet respectively. Waves may rise slightly at night into Wednesday. Rip currents are abnormally strong, plus water is hazardous with bacteria from storm run-off. Avoid the water.

Rain will pick up again in the morning commute hours. If possible, delay your travel or avoid traveling at all. There may still be standing water in roadways with several road closures still in effect.

Rain showers will be scattered and again heavy at times with strong wind activity. There is a chance of thunderstorms and hail, and even a special marine warning with a slight chance of waterspouts or tornados. Rain showers start tapering off in the afternoon.

Conditions improve greatly Wednesday, drying out from a ridge of high pressure. High temperatures will stay in the upper 50s to low 60s mostly.

The region will warm a few degrees Thursday. Clouds will increase through the day. On Friday, we develop another chance of rain showers with an approaching trough. Rain is likely Saturday, and chances linger into Sunday and Monday. This system is expected to be moderate, and not as strong as Monday's storm with 1 to 2 inches of rain over the weekend.
