While the official totals won't be confirmed until rainfall measurements are taken Friday afternoon, the National Weather Service underscored the storm's intensity.

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.”

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.

With rising water levels from the atmospheric river storm hitting the North Bay, Santa Rosa residents were preparing for the next round of rain. Andrea Nakano reports.
