San Francisco is preparing for a weekend marked by heavy rain and strong winds, courtesy of an incoming low-pressure system. The National Weather Service has issued advisories, highlighting potential hazards such as rainfall reaching up to 2 inches and wind gusts hitting 40 mph, particularly along the coast and in higher elevations. These conditions, typical of the transition from winter to spring, necessitate heightened caution. Residents are urged to secure outdoor items and prepare for possible power outages and transportation disruptions.
