The deadly and destructive flash flooding in Maryland is a reminder of similar danger in Colorado. There is flash flooding along the Front Range every summer.
The Maryland storm dumped around six inches of rain in just a couple of hours. In September of 2013, a heavy rain storm over Colorado measured over 24 hours dumped nearly 8 inches rain south of Colorado Springs, and six inches inside the city around the Ivywild neighborhood.
Emergency managers point out, a lot less water than this can be damaging and life threatening. "It doesn’t take much water to take you off your feet, said Colorado Springs Deputy Emergency Manager, Kevin Madsen, “You’re talking only a matter of inches. Six to 12 inches could knock someone down. Only 18 inches can actually move a vehicle."
Flash flooding is considered one of the top natural disaster threats in Southern Colorado. Colorado Springs has extensive information on the site CSready.org to explain the extent of the threat and how to protect yourself.
