LAS VEGAS (AP) - Most of Nevada is under a flash flood watch as unseasonably cool weather pushes rain across the region on the heels of one of the state's hottest July's ever.
Flash flooding closed some streets in northwest Las Vegas during the Monday morning commute. About an inch of rain fell in an hour on Mount Charleston, washing out several roads overnight.
A flash flood watch was in effect until 9 p.m. Monday in parts of Clark and southern Nye county, and in northern Nevada in parts of Elko, Lander, Eureka and Humboldt counties.
The National Weather Service says Sunday was the coolest Aug. 3 in Death Valley ever at 89 degrees, shattering the old record of 104 set in 1945. That after Winnemucca recorded its warmest monthly average temperature on record in July with 77.5 degrees.
