LAS VEGAS (KLAS) — A flash flood watch has been issued for the area northeast of Las Vegas in the area including Mesquite. A flash flood warning is in place for the Beaver Dam/Littlefield areas of Arizona, according to the National Weather Service (NWS).

Several areas in the Beaver Dam/Littlefield area are under orders to prepare for evacuation after the activation of SET status early Wednesday night.

“All homes in the area of the Highway 91 bridge in Beaver Dam should start preparing to evacuate,” according to a statement from the Mohave County Sheriff’s Office (MCSO). Neighborhoods include the Beaver Dam Estates, Pines to Palms, Clark Gable Dr., and Old Pioneer Rd. near Highway 91.

Warnings remains in place until late tonight along other parts of the “Arizona Strip.” Travelers on Interstate 15 should check weather conditions through NWS and monitor closures at https://twitter.com/mohaveroads.

Heavy rains and life-threatening flash flooding is predicted for the Beaver Dam Wash. Back country travel and unmaintained roadway travel is not recommended, MCSO said.

An NWS flood watch indicates river flows may increase quickly as rains fall on “a deep primed snowpack.”

The Virgin River and the Muddy River have seen flooding that has caused damage in past years. Washes in the area can fill quickly during heavy rains.

That watch will remain in place through Thursday afternoon. It affects a long list of towns and sites in Nevada, Utah and Arizona: Colorado City, Hiko, Moapa, Yucca, Golden Valley, Pipe Spring National Monument, Pioche, Valentine, Western Grand Canyon, Mesquite, Mt Trumbull, Kingman, Alamo, Wikieup, Panaca, Tuweep, Rachel, Dolan Springs, Caliente, and Overton.

Low-water crossings might flood, and travelers should keep an eye on streams and rivers.

According to Zion National Park’s website, The Narrows is currently closed to hiking and canyoneering. There are also closures at Kolob Canyons due to “active rockfall.”

The Lincoln County Sheriff’s Office announced the following road closures Wednesday morning:

  • The Nevada State Parks Division has closed Spring Valley State Parks until further notice due to heavy flooding.
