SALT LAKE CITY — Half of Utah is under flash flood watch as meteorologists say storms moving across central and southern parts of the state will bring heavy rain.

The National Weather Service in Salt Lake City said Tuesday that narrow canyons, creeks with steep terrain, washes that are normally dry and areas where wildfires have recently burned should all be avoided.

Forecasters warn that rockslides and mudslides are also possible.

The flood watch is in place until midnight Tuesday and covers Utah’s deserts, valleys and southern national parks.

The Weather Service issued a more serious flood warning for areas of Wayne, Emery and Sevier Counties near Capitol Reef National Park.

At least two inches of rain had fallen there by Tuesday afternoon and more is predicted.

Authorities warn even distant rain can create deadly, powerful flows of water in minutes.
