HILDALE, Utah (AP) — Zion National Park has closed its canyons because of a flash flood warning issued for much of southern Utah. The National Weather Service issued a flash flood warning Tuesday for Hildale, Utah, Zion National Park and other areas near the Utah-Arizona border. Park officials closed access to The Narrows, the tightest section of the canyon, until further notice. Hildale Mayor Donia Jessop says a large flood did come through the town and a few basements were flooded. But she says mitigation work has been successful so far. Another flash flood in Hildale washed away several cars in 2015, killing at least a dozen people.
