DENVER – After a dry weather pattern over the past several days, widespread thunderstorm and shower activity will begin to pop up late Monday afternoon and continue each afternoon until the weekend for the Denver metro.
The stronger storms will be capable of producing 1-2 inches of rain in less than an hour, which could lead to flash flooding along low-lying urban areas of the Front Range, small creeks and streams, and burn scar areas in the mountains, according to NWS meteorologists. Drivers were advised to avoid flooded roads and be ready to move to higher ground if flooding is imminent.
