SAN FRANCISCO – The Bay Area is ringing in the New Year under cloudy, breezy and damp conditions, as a subtropical moisture plume continues to move through Northern California Wednesday and into Thursday.
Subtropical moisture will bring steady rain
A mild but moisture-rich weather system is spreading rain across the region on Wednesday.Â
This system is tapping into subtropical moisture, helping produce periods of steady rain rather than brief showers.
Rainfall will be most persistent at times through the afternoon and evening, with wet roads and reduced visibility likely for the evening commute.Â
Winds will occasionally gust, especially near the coast and higher terrain.
Rain likely for New Year’s Eve celebrations
For those heading to the Embarcadero and San Francisco’s New Year’s Eve fireworks at midnight, expect cloudy skies, breezy conditions and a good chance of rain.Â
Slick sidewalks and roadways may also slow travel, so allow extra time and use caution.
