(KTVU) -- The latest storm will create a messy Wednesday morning commute.

Parts of the Bay Area are under flash flood watches, coastal flood, high surf, and or wind advisories.

Be careful driving, especially on bridges, where winds will be strong.

Roads will be wet, so the CHP says watch out for standing water.

Beachcombers, swimmers, and surfers also need to be careful.

There's a high surf advisory for much of California's coastline.

The National Weather Service warns that a combination of high tides, large swells and runoff from heavy rainfall can lead to coastal flooding from Sonoma to Monterey Counties, including the San Francisco Bay Shoreline.

Swells could possibly reach 20-feet Wednesday night.
