Residents on the Peninsula and in the interior East Bay woke up to a battering of southerly winds this Friday, as gusts reached up to 45 mph in some areas. The National Weather Service San Francisco issued a Wind Advisory from 4 AM through 11 AM, cautioning the public about potential tree damage and subsequent effects on roads and power grids. The advisory highlighted the combined impact of these strong winds and rain, indicating a potential for disruptions throughout Friday morning.
The weather front, characterized by a convergence of a warm, cold, and occluded front—known as the triple point—passed through the Bay Area around mid-day. This caused a few strong showers and raised a 10-20% chance for thunderstorms during a brief window around noon. According to the National Weather Service, "the moisture band is narrow and fast moving with this system," which seems to have brought in stronger winds than initially forecast. Before the skies cleared, residents experienced a chilly and breezy afternoon as the rain stopped.
Mariners were also advised of the perilous conditions at sea over the day and the next week, with gale warnings in effect for much of the coastal regions. The Area Forecast Discussion stated that "Gale force gusts and rough seas will move through the waters and create hazardous conditions through the day." For those on land, cold and wet contrasts will define the early spring sentiment, leading to a potentially light rain trend come Thursday and flatter weather patterns as the month progresses.
