Overexposure to the sun's harmful UV rays can cause sunburn and increase the risk of developing skin cancer, including melanoma. Protect yourself by wearing clothing that covers your skin, sunglasses, and a hat. Apply a broad-spectrum sunscreen with an SPF of 30 or higher every two hours, even on cloudy days. Minimize direct sun exposure during peak hours (10 AM to 4 PM) to reduce the risk.

Minor Expected Likely

Coastal Flood Advisory

Coastal Flood Advisory issued July 15 at 3:38AM PDT until July 16 at 4:00AM PDT by NWS San Francisco CA
Jul 15, 3:38 AM Jul 16, 4:00 AM
WHAT: Up to 1.5 ft of inundation above ground level is
possible in low-lying areas near shorelines and tidal waterways.

WHERE: Bayshore locations along the San Francisco and San
Pablo Bays.

WHEN: Until 4 AM PDT Thursday.

IMPACTS: Flooding of lots, parks, and roads with only
isolated road closures expected.

ADDITIONAL DETAILS: At the San Francisco tidal gauge, high tide
is expected to be 1.5 ft above normal (7.3 ft MLLW) at 12:48 AM
7/16. These predictions include both astronomical tides and
roughly 3-6 inches of additional water mainly from a combination
of thermal expansion and accumulated sea level rise since the
tidal datum was established (1983-2001). High tide varies up to
90 minutes earlier or later along the Pacific Coast and through
the San Francisco Bay, respectively.
