A Flash Flood Warning remained in effect Friday for west central Carbon and northwestern Emery counties as a series of rain-laden thunderstorms rolled through the central Utah area.
Of particular concern to the National Weather Service were mountain slopes denuded by the 2012 Seeley Fire, where little vegetation remained to absorb heavy rainfall.
At 1:45 p.m. Friday, the National Weather Service tweeted that a heavy rainfall had caused a debris flow on the Seeley Burn Scar that had flowed onto State Road 31 in Huntington Canyon. Additional runoff was expected through the afternoon.
Authorities were keeping a close watch over the Huntington Power Plant, upstream of the town of Huntington, the NSW said as part of the flood warning, which was issued at 8 a.m., was expected expire at 5:45 p.m.
The weather service said that during the six hours prior to 2 p.m., 0.65 inches of rain had fallen on the Seeley Burn Scar.
A Flash Flood Watch — effective Sunday afternoon through Monday afternoon — was issued for portions of eastern and southern Utah.
Widespread rainfall moving into southern Utah on Sunday was likely to bring enhanced runoff to dry washes and slot canyons, and burn scars would be at risk for debris flows, the weather service said.
