How it started
Heavy Rainfall Triggers Flood Warnings Across Southwest U.S.
What happened
The National Weather Service issued flood watches across much of Arizona, western New Mexico, and parts of southern Colorado following heavy rains. Flooding has affected the Four Corners region, with San Juan River flooding causing evacuations in areas upstream in Colorado and New Mexico. Officials in New Mexico reported that damage from the flooding could total $300 million.
Why it matters
The severe flooding has led to the announcement of federal disaster assistance for New Mexico. The event highlights significant infrastructure strain, as hundreds of homes along the San Juan and Animas rivers remained evacuated or without power while officials assessed the damage.
