Beach Safety - Distant Tropical Storms

Sprinkles or Very Light Rain/Low Lightning Chances

Tropical Storms and Hurricanes that are far away can still create deadly rip currents and waves, especially sneaker waves. Never assume that the ocean is safe, even if the weather is nice. For maximum safety, swim near a lifeguard (where applicable) and check beach conditions.

Sprinkles or very light rain with a low (5%) chance for isolated lightning strikes are forecast tonight into Monday morning and again Tuesday night into Wednesday morning. The region with the greatest potential will be the North Bay, the San Mateo Peninsula into northern Santa Cruz County. There is low to medium forecast confidence due to uncertainty regarding the instability or fuel for storms. If current instability forecasts remain unchanged, most locations across the Bay Area and Central Coast will NOT see rain or lightning. Check back for updates!
