WEATHER ALERT for High Surf, Gusty Winds, and Flooding Potential

Air Quality (as of 1:00PM)
GOOD to MODERATE for all reporting areas.
 
WEATHER STORY
Active weather will continue with a big climax this weekend. The next system approaches late Saturday, but only light rains are likely near the coast late. This will all lead up to the strongest system which will take aim at the West Coast Sunday. This system will be accompanied by a robust atmospheric river of moisture which will mean heavy rain. The most likely timing in our area will be Sunday afternoon through Monday morning. Gusty winds, heavy rain, minor flooding, and high surf can be expected. It is still several days out, so much can change in the meantime. Stay tuned to the forecast.

Saturday: Partly cloudy and slightly warmer with highs in the 60s to low 70s. Breezy for the valleys in the afternoon. Clouds thicken late with some light rain possible in the coastal hills.

Overnight: Increasing clouds and southerly winds. Occasional light rain possible mainly in the coastal hills. Lows in the 50s with a few 40s in the southern valleys.   

Sunday: Increasing clouds and increasing southerly winds throughout the day. An atmospheric river of moisture will take aim at the coast and slowly wash from north to south across the region beginning in the afternoon Sunday and lasting into the overnight. Winds will peak late in the day and then slowly taper off overnight from north to south. Highs in the 60s. See the alert products below for details on the rain, wind, and high surf:
