Early Storm Drenches Northern California
2 Sep
Summary
- Rain expected across Northern California on Wednesday and Thursday.
- Some areas may see their wettest September start in decades.
- Temperatures will be abnormally cool, 10-20 degrees below normal.

An unseasonably early storm is forecast to deliver much-needed rain to Northern California starting Wednesday, continuing through Thursday. The North Coast anticipates the heaviest precipitation, with potential accumulations of up to 2.5 inches in Del Norte County mountains. This system could mark one of the most substantial early September rainfalls in decades for cities like Santa Rosa and Eureka.
Beyond the downpours, abnormally cool temperatures will accompany the storm. Large portions of Northern California are expected to experience readings 10 to 20 degrees below seasonal averages, persisting into the upcoming weekend. Sacramento, in particular, may see its coolest first five days of September since 2000.
