A winter storm packing widespread rain, gusty winds, isolated hail and even snow hit the Bay Area Thursday, causing slick roads and spot flooding in various areas across the region, according to weather officials.
Heavy rain during the late morning and early afternoon hours prompted the National Weather Service to issue flood advisories across much of the Bay Area.
The storm was expected to bring anywhere from 1 to 3 inches of rainfall to the coastal mountain ranges and the North Bay, the weather service said. Most urban areas were slated to pick up 0.5 to 1 inch of rainfall. Less rain was expected in rain-shadowed valleys.
Hail pelted parts of San Francisco and the Santa Cruz Mountains. Fresh snow covered Mt. Diablo, Mt. Umunhum and the foothills near Mt. Hamilton.
Wind gusts were expected to range from 30 to 40 mph along the coast and in the hills, the weather service said.
The weather caused flight cancellations and delays at San Francisco International Airport. Travelers should check with their airlines for details about specific delays, airport officials said.
There is a slight chance of thunderstorms Thursday afternoon and evening, according to the weather service.
