HALLOWEEN STORM Hits Las Vegas First 4 MILLION Under Flood Threat, Up to 5 Inches Possible

“More than 4 million people across Arizona and the Four Corners are under a level 3 of 4 flood risk for Sunday, and the first wave of the storm already hit Las Vegas on Friday with hail up to ping-pong ball size, flash flood warnings, more than 4,000 customers without power and a lightning ground stop at Harry Reid International Airport. Forecasters expect an atmospheric river fed by the remains of Hurricane Vance to bring up to 5 inches of rain from Phoenix to Flagstaff through Monday. Archuleta County, Colorado, told people in low-lying areas of Pagosa Springs to evacuate, flood watches cover Zion, Bryce Canyon and Lake Powell, and Southern California is in line for a rare rainy Halloween before the storm sweeps across more than 35 states. Figures as of Friday evening, October 30, 2026.
