Rainy season returns! At atmospheric river will reach the West Coast on Friday and continue to hose down the coast through mid-week next week. The first disturbance will help get rain going around the Monterey Bay area later in the day on Friday followed by a second on Saturday. While most areas around the bay will only see periods of rain, it may be more persistent in the Santa Cruz Mountains which could lead to minor flood concerns. See the alert from the NWS below.

Air Quality: Good to Moderate


Overnight: Increasing clouds, both high and low. Some drizzle possible toward dawn for coastal areas. Lows in the low to upper 40s on the coast and upper 20s to low 40s inland.

Friday: Mostly cloudy with occasional sprinkles early, then an increasing chance of rain through the afternoon and especially from Monterey Bay northward. Increasing southerly winds throughout the day, bordering on “windy” for the exposed coast late. Slightly warmer, with highs in the 50s to low 60s.

*FLOOD WATCH*
… for Santa Cruz and Santa Clara Counties in effect from Friday afternoon through Sunday evening.

*Flooding caused by excessive rainfall is possible.

*Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas.

*Excessive rainfall is forecast through the region. Around 1-3 inches of rain is expected across the warned region by Sunday afternoon, with locally higher totals up to 5 inches in the higher elevations.

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.


Saturday: Mostly cloudy with gusty southerly winds at times, especially on the coast and in the mountains. On and off light to moderate rain, more likely in the north and toward the coast. Warmer, with highs in the upper 50s to mid 60s.

Extended: The atmospheric river will buckle northward for Sunday and most of Monday, though we’ll remain on the edge which keeps a chance of rain in the forecast for the Monterey Bay area. Southerly winds will be gusty at times and also keep a fairly mild air mass in place. The river will swing south with a weather system some time late Monday or Tuesday with a period of stronger winds and moderate to heavy rainfall. There may be an increased flooding risk in saturated areas by that time. Additional rain may be possible with lingering showers on Wednesday and a trailing system on Thursday. Temperatures will cool down behind the Tuesday system, however, so snow levels will also be lower by then.
