Severe weather moved through the Las Vegas valley Monday night diverting flights, causing power outages and prompting one rescue.
According to the Clark County Fire Department, one person was rescued who was trapped in a rain-swollen flood control channel. That person was not injured.
A massive power outage affected thousands of Southern Nevadan residents. At one point, a total of 41,000 customers were without power.
At last check, around 11:15 p.m., NV Energy’s website was reporting more than 33,000 people were still without power.
The City of Las Vegas tweeted that there were reports of at least 14 intersections that were dark due to the power outages, including Stewart and Mojave. The protocol for dark stoplights is to treat the intersection as a 4-way stop, the City of Las Vegas said.
