(03-09) 13:33 PST SAN FRANCISCO -- San Francisco could be in for a dusting of snow.

Forecasters with the National Weather Service said today that as much as an inch of snow could fall on Twin Peaks as a cold storm moves in tonight and Friday morning. The landmark hills are a mere 920 feet above sea level.

Accumulations could be substantial in the highest reaches of the Bay Area, the forecasters said. As much as 6 inches could fall on Mount Hamilton (elevation 4,213 feet), Mount Diablo (3,849 feet) and other local hills, the weather service said.

A snow advisory will be in effect from 9 p.m. tonight to 4 p.m. Friday for areas with elevations of 1,000 feet and higher, thanks to a storm system coming down from the Gulf of Alaska that is teaming up with cold air flowing down from Canada.
