Heavy rain over the weekend brought flash floods and orders to leave home in parts of Colorado, Utah, New Mexico and Arizona, the Associated Press reports. Some rivers began to drop on Monday. Others were still rising, AP says.

Officials had warned of “potentially catastrophic” flooding in Pagosa Springs, Colorado, AP reports. Readings late Sunday night showed the San Juan River began to go down after reaching 16.81 feet, the National Weather Service said, AP reports. A flood in 1911 that wiped out most of the town crested at about 17.8 feet, the sheriff's office had warned, AP says.

Flood-hit residents of Pagosa Springs who have not voted can “visit any voter center across the state to request and receive a replacement ballot,” Colorado's top election office said, AP reports. All roads in nearby La Plata County stayed closed on Monday, AP reports.

Farther down the river in New Mexico, new evacuations were ordered on Monday for some people in San Juan County, including some Navajo communities, AP reports. On Sunday, the Navajo Times reported that the river at Shiprock was forecast to crest above flood stage early Tuesday. The outlet said New Mexico Highway 170 had washed out and the Dennehotso Loop was left impassable.

In Arizona, Gila County ordered everyone in Gisela to leave, and Sedona and Camp Verde also ordered evacuations, AP reports. Tucson had swiftboat rescues, AP says. In Flagstaff, police searched for a man who fell into fast-moving floodwaters “and was not seen resurfacing,” police said in a statement, AP reports.

“Most of the rain is winding down,” David Byers, a weather service meteorologist in Grand Junction, Colorado, said Monday, AP reports. The next few days look drier, AP says.

What we know: Rivers are falling in Pagosa Springs but were still rising downstream in New Mexico on Monday.
What we don't: Whether the man in Flagstaff has been found, and how much damage the floods caused.
