Remnants of Hurricane Priscilla Drench Utah, Sparking Flash Flood Alerts

As of October 11th, 2025, the remnants of Hurricane Priscilla are continuing to churn through the state of Utah, bringing widespread flash flooding concerns to many of the state's outdoor destinations. The National Weather Service has expanded its existing flood watch to include the Uinta Basin, adding to the numerous parts of central, eastern, and southern Utah already under alert.

Meteorologists warn that the south slopes of the Uinta Mountains are especially at risk of flash flooding as the system moves through. Some flash flood warnings were already issued on Thursday for areas near Lake Powell and Zion National Park, with one location in southern Utah receiving 2.6 inches of precipitation by Friday noon.

The weather service advises that flash flooding is "expected" again on Friday near Zion, Lake Powell, Snow Canyon State Park, Red Cliffs National Conservation Area, and Grand Staircase-Escalante National Monument. The same risks are deemed "probable" for Arches, Bryce Canyon, Canyonlands, and Capitol Reef national parks, as well as the Natural Bridges, Grand Gulch, and San Rafael Swell areas.
