San Francisco and the broader Bay Area feel the brunt of a potent atmospheric river, bringing significant rainfalls and strong winds that have prompted the National Weather Service (NWS) to issue multiple watches and warnings. According to the NWS San Francisco, a Flood Watch is in effect through Saturday evening, with the expectation of minor flooding impacts across most of the area. Additionally, strong winds are combined with heavy rains, resulting in downed trees and power outages, particularly along the Santa Cruz Mountains and Big Sur Coast, where impacts could be more acute.

This morning's journey was perilous for city dwellers and commuters, as per NWS San Francisco. The strong winds and rain are anticipated to cause significant disruptions, with the added likelihood of shallow landslides on Thursday morning. Localized flooding and power outages are expected to continue, especially in urban areas. This, compounded by high surf conditions, has created what could only be described as a complication of typical Bay life.

Travel could become particularly treacherous. A High Wind Warning along the Pacific coastline signifies the risk of gusts up to 60 mph and isolated gusts reaching 80 mph in higher elevations. According to the NWS Forecast for San Francisco, the Wind Advisory spans the interior Bay Area, warning residents of potential gusts up to 60 mph. These factors increase the potential for property damage and widespread power outages.

The coastline is under a High Surf Warning until the early hours of Saturday. West-facing beaches are predicted to see waves of 20 to 30 feet, and the non-west-facing counterparts are not far behind. This presents risks to life and property. Swimmers are advised to avoid the water, as sudden immersion in these conditions can lead to cold water shock, increasing the risk of drowning. In addition to the surf conditions, isolated thunderstorms are expected Thursday, bringing with them the threats of lightning and small hail.

Social media updates through NWS Bay Area's Twitter post indicate that while the North Bay is clearing from the heaviest rainfalls, showers may persist, signaling a brief respite within a prolonged weather event. Residents are advised to stay current with local weather forecasts and heed all advisories and warnings as the region braces for continued impact through the weekend.
