“This is a very dangerous situation,” according to a post on the city’s Facebook page. “Please stay clear of Mill Creek.”
In Grand County, the Kirby, Shumway, Sunny Acres and Old City Park roads are closed due to the potential for flash flooding.
NWS also issued a flash-flood warning Tuesday evening for the town of Springdale just outside Zion National Park.
Water levels and the rate at which water is flowing can change quickly, according to the National Weather Service. The NWS offered the following tips for anyone caught in a flash flood:
- Get to higher ground and out of areas subject to flooding.
- Do not dive or walk into flooded area. It only takes 6 feet of water to knock an adult off their feet.
- Stay informed by monitoring local radar, TV, radio, internet, or social media for updates.
