The story, neutrally told

Remnants of Hurricane Polo battered the US Southwest on Tuesday, flooding roads and forcing residents of small New Mexico towns to evacuate over concerns about a dam failing. CBS News reported that water spilled over a 20-foot dam and that nearly a third of the country was at risk of flash floods. Newsweek named the structure as McLeod Dam and said the National Weather Service issued a flash flood emergency covering the Hatch Valley in Doña Ana County because of its imminent failure.

Doña Ana County officials said the Rincon Arroyo breached levees near the Rincon water treatment plant, and the weather service issued a flash flood emergency for Rincon. County public safety officials ordered people in Rincon, Salem and Garfield to evacuate immediately, and two shelters were opened. The Associated Press, as carried by NPR and the New York Post, said residents were later told to evacuate from Hatch and Placitas as well.

Arizona authorities reported several water rescues, and a helicopter rescued three people in Utah's Zion National Park. Polo struck Baja California Sur with 110 mph winds, per AP, then weakened to a tropical storm moving inland; BNO reported a second landfall in Sonora. Forecasters expect the flood risk to spread to the central US later in the week, with Tropical Storm Rachel adding moisture.

AP noted an unusually soggy September had saturated the ground, speeding runoff.
