A thunderstorm dropped heavy rain in parts of the Las Vegas Valley on Monday evening, leaving behind flooded roadways that made life difficult for motorists for several hours.

The hardest-hit areas included Lone Mountain and Summerlin in the northwest, which received 0.75 to an inch of rain, National Weather Service meteorologist Chris Stachelski said. The eastern part of the Lakes tallied 1.5 inches of rain.

Stachelski said the average rainfall around the valley was about 0.25 inch, with North Las Vegas only getting a trace.

Firefighters responded to a dozen weather-related incidents in the area bounded by Rainbow Boulevard to the west, Interstate 15 to the east, Alta Drive to the north and Desert Inn Road, Las Vegas Fire & Rescue spokesman Tim Szymanski said.

Firefighters performed 10 swift-water rescues, the first at 7 p.m. on Charleston Boulevard at Community College Drive and the last at Rancho and Teddy drives, near Palace Station, at 9 p.m., Szymanski said. There were no reported injuries.

Slippery conditions led to a pair of rollover accidents in the western valley, one on Summerlin Parkway and the other on Durango Drive, Szymanski said.

Clark County firefighters tended to stranded motorists near the Linq.

Flooding made travel on Charleston Boulevard near Rainbow Boulevard dicey, and Koval Road north of Flamingo Road was closed until water receded.

The storm had knocked out power for about 800 Southern Nevada customers as of 8:15 p.m., NV Energy reported. By 10:45 p.m., that number had dwindled to 400.

A flash flood warning was in effect until about 10:30 p.m.

There were reports of quarter-sized hail in Summerlin at the 215 Beltway and Cheyenne Avenue, meteorologist Chris Stachelski said.

By 7 p.m., rain — accompanied by lightning and thunder — began to fall in the Green Valley area of Henderson.

Monsoon season is to thank for the rain.

High temperatures, meanwhile, are expected to remain about 100 degrees through Wednesday, and the latter half of the week may see highs in the mid to upper 90s, meteorologist Mike Paddock said.

Low temperatures should stay in the low 80s through Wednesday morning before dropping to the low 70s for the rest of the week, he said.
