Departures were postponed and arrivals were delayed after the airport ordered a stop on fueling operations during lightning strikes, airport spokeswoman Linda Healey said.
Firefighters responded to more than 20 calls about people in stalled cars, county spokesman Dan Kulin said. A Las Vegas police helicopter was dispatched during the height of the storm to pluck several people from swamped vehicles on area roadways, Officer Bill Cassell said.
After responding to numerous 911 calls, officials in Clark County, North Las Vegas, Henderson and Las Vegas said Tuesday there were no confirmed reports of serious injuries.
National Weather Service meteorologist Michael Staudenmaier said more than 1.75 inches of rain were reported in downtown Las Vegas.
The rainfall amounts put the region on pace to exceed the 4.5 inches of rain it normally gets in a year, he said.
There, a thunderstorm that dropped more than the average annual rainfall on parts of the Coachella Valley in one night alone caused flooding at two mobile home parks, forced road closures and dampened a school, officials said Tuesday.
The early morning thunderstorm stalled for six to eight hours over Mecca and Thermal, two towns at the southern tip of the Coachella Valley 150 miles southeast of Los Angeles. Thermal is about eight miles from Indio, Calif., where the annual Coachella Music Festival is held.
The storm dropped 5.51 inches of rain near Mecca and 3.23 inches of rain near Thermal, meteorologist Mark Moede said. The average annual rainfall in Thermal is just shy of 3 inches, he said.
In Thermal, the downpour flooded the Desert Mobile Home Park better known as Duroville, causing the park to lose one of its wells and creating concerns about overflow from sewage ponds used to treat waste, said Ray Smith, a Riverside County spokesman.
