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.

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.”

Record-breaking rainfall propelled by a powerful atmospheric river drenched the Bay Area over the weekend, and though more is on the way, forecasters are expecting the upcoming system to pale in comparison to the historic storm.
