Monsoon Flood Threat in the Southwest; Hot in the South and Northwest

Monsoonal heavy rain will continue flash flood potential across the Southwest and Intermountain West to the central and southern Rockies through this weekend, especially in complex terrain, burn scars, and urban areas. Excessive heat and humidity with heat indices over 110 degrees will be common over much of the Deep South and interior Northwest this weekend. Read More >

U.S. Drought Monitor - Colorado Drought Severity Classification
U.S. Drought Monitor for Colorado

Category

Description

D0

Abnormally Dry

Possible Impacts: Going into drought: short-term dryness slowing planting, growth of crops or pastures. Coming out of drought: some lingering water deficits;  pastures or crops not fully recovered

D1

Moderate Drought

Some damage to crops, pastures; streams, reservoirs, or wells low, some water shortages developing or imminent; voluntary water-use restrictions requested

D2

Severe Drought

Crop or pasture losses likely;  water shortages common; water restrictions imposed

D3

Extreme Drought

Major crop/pasture losses;  widespread water shortages or restrictions

D4

Exceptional Drought

Exceptional and widespread crop/pasture losses; shortages of water in reservoirs, streams, and wells creating water emergencies
