Overview

• Fleet Week events in San Francisco are expected to be mostly dry, with only isolated showers Friday and the clearest conditions on Sunday near 70 degrees.
• The National Weather Service says a stronger low will push a cold front through Friday, dropping some North Bay lows into the mid-40s.
• Confidence is rising that a widespread storm arrives Monday into midweek, with San Francisco likely to receive roughly 0.5 to 2 inches of rain depending on the track.
• Wind gusts could reach about 30 mph with the early-week system, knocking down leaves that can clog drains and cause localized flooding, giving residents a window this weekend to clear debris.
• Mariners should expect west-southwest winds of 10 to 20 knots Friday through the Golden Gate, shifting west-northwest at similar speeds Saturday and Sunday with a light chop.
