Bay Area Under Coastal Flood Advisory
A coastal flood advisory has been issued for the San Francisco Bay Shoreline, including Fremont, through Tuesday afternoon. Authorities warn that minor flooding is possible in low-lying coastal areas during high tides. The advisory covers the period from Sunday, February 14th, through Tuesday.
- The flooding is caused by the convergence of seasonal high astronomical tides, known as king tides, with a series of storm systems moving through the region. - The National Weather Service predicts tide levels at the San Francisco tidal gauge to reach 7.1 feet on Tuesday morning, approximately 1.2 feet above normal, with up to a foot of inundation possible in low-lying shoreline areas. - This event is part of a larger weather pattern expected to bring rain through Friday, with southerly wind gusts reaching up to 45 mph along the coast and in higher elevations. - In Fremont, the areas most vulnerable to this type of flooding include the Baylands and the south Warm Springs district. - Long-term projections for Alameda County indicate a potential sea-level rise of six inches by 2030 and 36 inches by 2100, which would threaten infrastructure like I-880 and the Union Pacific railway in South Fremont. - The current weather pattern involves multiple low-pressure systems, and historically, the most damaging storms in the Bay Area have resulted from the combination of extratropical cyclones and atmospheric rivers. - Forecasters warn that the cumulative impact from these repeated rounds of rain increases the likelihood of not just coastal flooding, but also potential landslides as the week progresses.
