Thunderstorms over the eastern portion of the Las Vegas Valley have weakened, and the National Weather Service has canceled its flood advisory.

A flash flood warning was issued around 12:30 p.m. Sunday and lasted until 2:30 p.m., when it was replaced by the flood advisory. It covered areas such as Henderson, Silverado Ranch, Sam Boyd Stadium and Nellis Air Force Base.

The weather service reported 6 inches of water on southbound Maryland Parkway from Cactus Avenue to Silverado Ranch Road. There also was flooding near Spencer Street and Silverado Ranch Road.

One of the service's rain sensors indicated nearly half an inch of rain in about a half hour Sunday near Southern Highlands, meteorologist Ryan Metzger said.

"Afternoon thunderstorms in monsoon season are pretty typical," Metzger said.

The storms were expected to skip over the Mount Charleston wildfire, as they were likely to stick mainly to the east side of the valley, Metzger said.

Flash floods usually affect roadways and underpasses, as well as naturally low-lying areas. The weather service advises people to avoid trying to use flooded roadways or walk through floodwater.
