Thick fog had windshield wipers on this morning for the commute into San Francisco, and possible showers and a thunderstorm may keep them on for much of the day. Temperatures around the Bay Area were expected to hit the high 60s or low 70s throughout the day, with slight winds. A 20-degree drop is expected tonight, with partly cloudy skies and temperatures in the high 40s or mid-50s. The temperature drop and chances of rain are expected to continue Tuesday.
Commutes into San Francisco from the East and South Bay areas are slow this morning behind traffic incidents on Westbound U.S. Highway 80 and Northbound U.S. Highway 101.
The Bay Bridge is slow due to an obstruction blocking the second lane from the left, and traffic is backed up through the metering lights in Oakland.
On Interstate 280, an accident involving the center divide south of state Route 92 on northbound Highway 101 slowed traffic, but it was reported clear about 6:30 a.m. After the clearance, Monday morning traffic is still moving slowly the length of the Peninsula on Highway 101.
East Bay trains were also running cautiously after a Union Pacific train struck and killed a person just after 4 a.m. The primary line affected was ACE Train 1, a commuter line between Stockton and the South Bay.
