If it's not raining, why is it flooding?

A unique double-threat of historic summer high tides and deadly sneaker waves will impact local coastlines through the middle of the week.   1. MORE Historic Summer Tides. Nightly localized flooding will continue along low-lying areas of the San Francisco Bayshore and Pacific Coast. Sunday's new moon and lunar perigee, combined with warm ocean water and rising sea levels, are pushing tides up to 2.0 feet above normal .This event is on track to become the highest summer tide ever recorded in the Bay Area. Coastal Flood Advisory is in effect until early Wednesday morning for the inner Bayshore. Avoid parking or driving in low-lying coastal areas.  2. Beach Warning: A Beach Hazards Statement is active across all Bay Area Pacific beaches through late Tuesday night. Monday temps will be holding from 65 at the Coast to 90 Inland.   The west side of San Francisco (including the Sunset and Richmond districts) and the immediate Pacific coast will remain locked in this foggy, sunless pattern for the next few days.
