A flash flood warning is in effect through at least 9:30 p.m. for central Clark County, including Las Vegas, according to the National Weather Service.

As of 6 p.m., more than 4,000 people were without power in the Las Vegas Valley, according to NV Energy. An estimated 30 outages were impacting 4,250 customers.

Throughout the valley, drivers got stuck in flooded roads at major intersections, including Las Vegas Boulevard and Cheyenne Avenue in the northeast valley and Blue Diamond Road and Rainbow Boulevard in the southwest.

The National Weather Service advised heavy rain could lead to flash flooding, and winds of 40 mph or more were in the forecast through Friday night.

Officials warned the public not to try to cross flooded roads. Six inches of standing water is enough to sweep a grown adult off their feet, and 18 inches of water is enough to carry away a car.
