What happened
The National Weather Service issued a widespread flood watch for Arizona, New Mexico, Utah, and parts of Colorado due to expected heavy monsoon rain in the Southwest. Separately, an isolated electrical storm knocked out power for nearly 9,600 customers in Durango, New Mexico, for about 30 minutes after lightning struck. The National Weather Service warned that localized rainfall could trigger flash floods in canyons and along waterways.
Why it matters
The monsoon season is impacting weather patterns across the Southwest, including New Mexico and Arizona. The combination of heavy rainfall and electrical storms poses risks to local infrastructure, such as power grids and water supply systems like the Hoover Dam.
