It's another wet start to the work week around the Bay Area.
If you woke up anywhere from Morgan Hill to Napa this morning, chances are you heard the rainfall. The first band of a new storm system moved through early Monday morning and is expected to stick around long enough to make the afternoon commute messy as well.
About 2-4 inches of rain is expected to come down Monday, adding to ground already saturated from days of downpours last week, NBC Bay Area Meteorologist Craig Herrera said. The four inches is likely in the North Bay Hills and the Santa Cruz Mountains.
The all-day rain will be bad news for the Santa Cruz Mountains, where mudslides are a real threat. Winds may briefly turn breezy enough to cause some isolated power issues.
Floods are possible in North Bay creeks in areas including San Anselmo, Corte Madera and Petaluma. Don't be surprised if there's also some street flooding in San Francisco and areas on the Peninsula as heavier rain begins moving into those parts, NBC meteorologist Rob Mayeda said.
The ocean will be a sight to see as this system could churn up waves in the 10-18 foot range. A high surf advisory goes into effect at noon and lasts into Tuesday. The constant battering will also mean more erosion along the coastline.
Like to ski or snowboard? Then you'll like all this moisture as it turns to snow in the higher elevations. The Sierra will get a couple feet of snow above 7000 feet as a result of this blast.
Tuesday will bring just a bit of relief as the system starts to make its way south. But there will still be scattered showers and possibly hail and lightning bringing up the rear.
