El Niño Monsoons Bring Rain but No Relief for Colorado River Crisis
El Niño Monsoons Bring Rain but No Relief for Colorado River Crisis
US · Published Sep 17, 2026
Monsoon rainfall is forecast to impact parts of the drought-stricken southwestern United States this week, with moderate precipitation expected through Friday.
The heaviest rainfall is anticipated in Western and Northern New Mexico, Eastern Arizona, and Southwestern Colorado, with some areas receiving 2 to 4 inches of rain.

Impact & Risks

The rainfall may temporarily alleviate drought conditions in some areas, but it is unlikely to reverse the multi-decadal drought that has plagued the Colorado River Basin since the mid-1990s. Flash flooding risks are elevated in regions receiving heavy rainfall. Lake Mead, a critical water source for 40 million people and 5.5 million acres of farmland, remains at record-low levels, with its water level dropping to approximately 1,040 feet in August 2026. The region requires sustained rain and snow over several years to address the water crisis effectively.
