Several rounds of heavy rain occurred across northwest California from October 21st to October 25th. The first round of heavy rainfall was associated with a frontal passage, and that event yielded rainfall rates sufficient for debris flows occurring across the River Complex burn scar. The next heavy rainfall event was associated with a classic atmospheric river on October 24th. Impacts were mainly limited to nuisance flooding.
