The Bay Area is bracing for a weekend of adverse weather, with rain and strong winds expected to arrive starting Friday evening. Meteorologists are tracking a weather system from the Pacific Northwest that will bring cooler temperatures and increased precipitation to Northern California. Wind speeds could reach up to 30 mph, particularly in coastal and higher elevation areas, potentially disrupting outdoor activities and causing minor inconveniences. Residents are advised to take precautions, such as securing outdoor items and avoiding unnecessary travel during heavy rain or high winds.
