COLORADO, USA — Storms produced heavy rainfall Tuesday, prompting a Flash Flood Warning that lasted until 10 p.m. for an area including Fort Morgan, Brush and Wiggins, where street flooding was reported.
The National Weather Service (NWS) in Boulder reported torrential rain just west of Lyons, where 1.5 inches of rain was recorded in 15 minutes and just over 2 inches in half an hour. A Flash Flood Warning for that area expired at 8:15 p.m.
People living in areas where Flash Flood Warnings are in effect were urged to move immediately to higher ground and to avoid walking or driving through floodwaters.
Heavy rain and strong winds took down trees and power lines in Berthoud, and people in Conifer reported the hail was some of the worst they remember.
In the foothills of southwestern Jefferson County, water washed away huge sections of soil near Buffalo Creek.
NWS issued a Flood Advisory for the Cameron Peak Burn Area until 11:15 p.m. The additional rain expected there would result in minor flooding, according to NWS.
