One of the strongest rainstorms of the season is set to gush over the Bay Area on Thursday just as unusually high tides and blustery winds hit, making for what forecasters expect to be a day of mayhem.

City work crews were gearing up for the super soaker that’s forecast to dump up to 2 inches throughout the day in San Francisco and in the East Bay, and twice that amount in parts of the North and South Bay. Commuters all over the Bay Area should expect hellish driving conditions during the morning and afternoon, when the most intense rain sweeps through.
