Another Round of Heavy Rain and Mountain Snow in California; Snow in the Great Lakes and Northeast

Another round of heavy rainfall will renew concerns for additional flash flooding and landslides in southern California around burn scars and coastal mountain ranges.

Overview

Widespread heavy rain fell from the end of August through early September across the region. Rainfall totals approached 8 inches across portions of eastern IA and northwest IL, with locally heavier amounts due to thunderstorms. This water fell across already saturated soils, and eventually found its way into area rivers and tributaries. This led to significant rises of river levels, and eventually minor to major flooding. The Wapsipinicon, Rock, English, Skunk, Iowa, Cedar, Pecatonica and Mississippi Rivers were all affected.
