Coastal Flood Advisory

Hot conditions Wednesday across the Central Coast interior will bring an increased risk for heat illnesses if outdoors for long periods, especially with physical exertion.

A Coastal Flood Advisory for the North Bay Interior Valleys and San Francisco Bay Shoreline is in effect through the early morning Thursday. Higher than normal astronomical tides will lead to high tides up to 1.5 ft above normal which could lead to flooding of lots, parks, and roads with only isolated road closures expected. However, these tides are expected to be lower than June's astronomical tides, so areas not affected in June can expect the same over the next week.
