California is known to experience severe precipitation events, characterized by days where the combined two-day total of rainfall exceeds 1 inch. Extreme precipitation in California often comes in the form of an Atmospheric River. The severity of these events can cause harm to natural and working lands as well as their surrounding areas. As such, we have created a list of resources intended to help land managers monitor, prepare for, and respond to extreme precipitation events.
NOTE: If you know of any extreme precipitation resources relevant to California’s natural and working lands that are not on this list, please contact the California Climate Hub Coordinator, Devon Johnson.
