Hurricane Polo Remnants Force Evacuations in New Mexico Towns as Dam Failure Threatens Rio Grande Communities

Remnants of Hurricane Polo battered the US Southwest on Tuesday, September 29, 2026, flooding roadways and forcing residents in small New Mexico towns to evacuate over concerns about a dam failing, according to multiple NPR affiliates and the Associated Press. The potential failure of a dam in south central New Mexico prompted evacuations in three small communities with hundreds of residents along the Rio Grande—Rincon, Salem, and Garfield—where people were told to seek higher ground immediately. Residents were later told to evacuate from nearby Hatch, home to prized green chile crops, and farther north in Placitas. Polo had struck the Mexican state of Baja California Sur in the morning with maximum sustained winds of 110 mph before crossing the Gulf of California and weakening to a tropical storm as it moved inland to the northeast. By Tuesday evening, the New Mexico Department of Transportation reported flooded roads and debris on highways across the state, while parts of Arizona had become especially drenched, leading to several water rescues.

Hundreds of residents in Rio Grande communities face evacuation during harvest season for chile crops that underpin the local economy. Whether the dam holds or fails will determine whether evacuations remain precautionary or escalate into longer-term displacement, according to the National Weather Service in Albuquerque, which warned residents not to drive through flooded roadways.
