Flash flood watch issued

Aspen Times Staff Report

The entire Roaring Fork Valley is under a flash flood watch that began this morning and could run through tomorrow morning, according to Greg Berman, meteorologist for The Aspen Times.

The National Weather Service has also issued a flash flood watch for much of the Western Slope, as a result of monsoon moisture that originated in Mexico and dumped heavy rains on Las Vegas over the past few days, Berman said.

“A flash flood watch means that flash flooding is possible, but not necessarily imminent,” Berman explained. “A flash flood warning means flash flooding is imminent.

“Las Vegas normally gets four inches of rain a year, and to give this storm some perspective, they’ve had close to nine inches of rain in the last few days and they’re still getting it – they could get more.”

Berman said the system that drenched Vegas is shifting to the east, and is now heading from Nevada toward western Colorado.

“If it holds together, some place on the Western Slope is going to get popped pretty good, but it may dissipate,” he said.

Berman warned that prolonged monsoon-type rains could cause flooding in surrounding streams and rivers, and especially in low-lying areas.

“This is typical this time of year, though it’s a little atypical for it to get this heavy, like what hit Las Vegas a few days ago,” Berman said. “This is the best chance Aspen has for heavy rains this summer.”
