Heavy rainfall and severe storm weather have led to significant flash flooding events across the United States (US) over the past week. In Clark County, Nevada, flooding began Thursday afternoon, August 11, after monsoon storms produced torrential rains along the Las Vegas strip for the second time in a two-week span. The National Weather Service (NWS) issued a flood advisory late Thursday cautioning local residents not to drive through low-lying or poor-drainage areas. The city’s total rainfall of 0.58 inches brought its precipitation total for this monsoon season to 1.28 inches, the most recorded in a decade. Local authorities reported two fatalities as the result of flooding in flood control channels. More than 17,500 people reported power outages in the central and western regions of the Las Vegas valley as a result of the storm.

In West Virginia, flash floods prompted dozens of emergency water rescues on Monday, August 15, as heavy rainfall brought two to five inches of rain in Kanawha and Fayette counties. Local officials reported at least two destroyed bridges and 100 damaged homes as a result of the storm. The storm also resulted in downed trees, disruption to potable water systems, and power outages for more than 2,000 people. In response to the severe flooding throughout the region, Governor Jim Justice declared a State of Emergency for both counties on August 15.
In addition, excessive rainfall and flash flooding led to road closures and mudslides in Colorado this week. According to San Miguel County authorities, at least four mudslides caused highway obstructions near Keystone Hill Monday afternoon, August 15. Dozens of flood and severe weather warnings were issued throughout the state, as some parts of the south metropolitan area received considerable urban flooding. In Broomfield, Colorado, the NWS recorded over three inches of rain Tuesday morning, August 16, totaling nearly 25 percent of the region’s average annual rainfall in less than a day.
