Upcoming Rainfall and Coastal Flooding

The Bay Area is bracing for a significant weather event as rain is forecast to return on Wednesday, December 28, and continue through New Year's Eve and into early next week. The National Weather Service (NWS) predicts that the heaviest rainfall will occur in the North Bay, Santa Cruz Mountains, and along the Big Sur coast, with totals potentially reaching 4 to 6 inches by Sunday, January 1. Most other areas are expected to receive between 1 and 3 inches of rain.

In addition to rainfall, coastal flooding is anticipated due to king tides combined with a storm surge from Wednesday through Sunday. High tides in San Francisco are projected to reach up to 1.8 feet above normal on Friday and Saturday mornings, which may lead to flooding of coastal roads, parks, and parking lots, although only isolated closures are expected.

Timeline of Weather Events

  • New Year's Eve (December 31): Rain will begin to overspread the region late in the morning, with steady showers continuing into the evening. Rainfall totals for most cities are expected to be around 0.5 inches. Winds are predicted to be light, minimizing the risk of downed trees or power outages. Residents are advised to carry rain gear if attending outdoor celebrations.
  • New Year's Day (January 1): Another storm is expected, categorized as a Level 1 on the ABC7 Storm Impact Scale, indicating light impacts.

Official Statements and Responses

The National Weather Service has urged residents to remain vigilant about changing conditions, particularly in flood-prone areas and along the coast. They have highlighted the potential for fast-rising creeks and streams, which could pose risks to low-lying neighborhoods and urban streets.

Criticism and Opposition

While the forecasts indicate manageable impacts for most areas, some residents express concern over the potential for flooding and property damage, particularly in regions with a history of drainage issues. Critics argue that the city should enhance infrastructure to better handle heavy rainfall and storm surges.
