Friday was the wettest day of the 2024 in many areas, including San Francisco, which received 2.97 inches of rain — or 13% of its annual yearly rainfall in one day — and Oakland, which received 2.46 inches in one day. San Jose saw less on Friday, .72 inches, for its wettest day since Feb. 2, when .87 inches fell.

This week’s atmospheric river storm smashed some heavy rainfall records in parts of the Bay Area, especially the North Bay, before mostly petering out by Saturday morning. Downtown Santa Rosa received 12.

Downtown Santa Rosa broke a century-plus record for having the most amount of rain within a 72-hour period — 12,7 inches. The previous record was 9.72 inches. “We broke it by a healthy margin,” Flynn said. “We’ve never seen that much of rain over three days since we started recording.”
