Summer storms moving over the Dixie area have caused some minor flooding in parts of Washington County.

There are reports of flooding in the Dameron and Diamond valleys, as well as parts of Zion National Park, from storms that moved over the area late Monday. The heavy rains caused culverts and creek beds to spill over, but nothing more, authorities said.

"There was no damage that we're aware of to any structures and property," Washington County Sheriff Kirk Smith said Tuesday.

In Zion National Park, flash flooding hit the popular Subway hiking area. Most groups were out before any flooding occurred, said park spokesman Ron Terry.

"There was one group that had not emerged from the flash flooding," he said on Tuesday.

They had to go for higher ground but came out of the area on their own about 9:15 p.m. Monday.

The National Weather Service has issued a flash-flood watch for most of southern and central Utah through tonight as thunderstorms with heavy rain move across the area. The Weather Service urges anyone planning to be outdoors to be extra cautious and avoid flood-prone areas.

In northern Utah, storms will be moving across the area today, bringing a chance of rain showers along the Wasatch Front.
