ARkStorm

A USGS model image shows the enormous atmospheric river that may have been present during the 1861–1862 flood event.

An ARkStorm (for Atmospheric River 1,000) is a "megastorm" proposed scenario based on repeated historical occurrences of atmospheric rivers and other major rain events first developed and published by the Multi-Hazards Demonstration Project (MHDP) of the United States Geological Survey (USGS) in 2010[1] and updated as ARkStorm 2.0 in 2022.[2]
