Overview

• The National Weather Service reissued the coastal flood advisory from 8 p.m. Tuesday to 1 a.m. Wednesday for San Francisco County, the Bay shoreline and North Bay Interior Valleys.
• Tides at the San Francisco gauge are forecast to crest at 1.11 feet above normal around 9:57 p.m., higher than Monday’s peak of 1.04 feet.
• Officials warn that minor flooding could submerge roads, parks and parking lots, potentially causing isolated closures and hazardous driving conditions.
• A small craft advisory cautions inexperienced mariners against navigating the Bay’s choppy waters during peak tidal periods.
• Meteorologists attribute the rare summer king tides to the alignment of lunar perigee, a new moon and solar feature interaction boosting tidal surges.
