Flood advisory extended in Clark County
The National Weather Service (NWS) Las Vegas extended a flood advisory for the Las Vegas Valley through 9 p.m. Monday, warning of moderate to heavy rainfall, gusty winds exceeding 40 mph, and nuisance flooding across major areas including Las Vegas, Henderson, North Las Vegas, and Boulder City.
The continued rain, combined with temperatures well below average for early May, has led to ponding on roads and hazardous driving conditions throughout the metropolitan area.
Historic rainfall for early May
By 4 p.m. Monday, Harry Reid International Airport had logged 0.18 inches of rainfall, increasing the monthly total to 0.43 inches (10.92 mm). This impressive figure is pushing May 2025 into the ranks of one of the ten wettest Mays on record in Las Vegas.
For context, the five wettest Mays recorded in Las Vegas history are:
- 0.96 inches in 1969
- 0.90 inches in 1987
- 0.84 inches in 1971
- 0.80 inches in 2019
- 0.72 inches in 1977
While May is typically one of the drier months for southern Nevada, this year’s totals are significantly bucking the trend.
Wind gusts and cooler air dominate the valley
In addition to the rainfall, gusty winds reaching over 40 mph are sweeping through Clark County, contributing to wind chills and a cooler-than-usual atmosphere. Residents and travelers in urban centers and along desert roadways are being affected by blowing dust, reduced visibility, and scattered debris.
