Flash-flood watch for Las Vegas Valley

Updated September 8, 2017 - 9:52 pm

A cool, but wet start to the weekend should continue before drying out and heating up by Monday, the National Weather Service said.

“We had several rounds of storms” on Friday, meteorologist Chris Outler said.

Clark County remains in a flood watch until 5 a.m. Monday.

Outler said the multiple storms Friday were unusual. They were fueled by a storm system off the coast of California, he said.

The area near Green Valley Ranch in Henderson received the most rain in the Las Vegas Valley on Friday, he said, raining between three-quarters of an inch and an inch depending on the spot. McCarran International Airport received about .35 inches of rain by 9 p.m. Friday.

The storms and cloud cover combined to cool the valley down to a high of 84 degrees Friday.

“It’s one of the coolest days we’ve had in quite some time,” Outler said.

It’s the valley’s coolest high since May 19, in fact, he said. The temperature recorded at the airport Friday evening dropped to 69 degrees, which Outler said marked the first time the valley has fallen below 70 since June 13.

Several arriving and departing flights at the airport were delayed Friday night. However, spokesman Paul Bobson said he couldn’t confirm whether the flights were delayed due to storms.

Saturday’s forecast high remains cooler at 86 degrees paired with a 60 percent chance of storms. The forecast high jumps to 94 on Sunday and 98 on Monday. The higher temperatures coincide with a smaller chance of rain; 20 percent for both days.
