Summary:<\/h3>\n

Wednesday was another wet day for much of Colorado. It started off with morning showers and thunderstorms, including snow at high elevations, for the Grand Valley, Western Slopes, Central, and Northern Mountains associated with the eastward progression of a strong shortwave trough<\/span>. Another morning of heavy rain combined with high accumulations yesterday resulted in several western locations experiencing flooding and debris flows.<\/p>\n

A Flash Flood<\/span> Warning<\/span> was issued for the Grizzly Creek burn area before 9 am, indicating that flash flooding<\/span> was already occurring in Glenwood Canyon due to heavy rain and thunderstorms, as per emergency managers. I-70 was closed by CDOT<\/span> in both directions after the warning<\/span> was issued – CDOT<\/span> also confirmed a mud flow in the canyon, as seen in the tweets below.<\/p>\n

#CDOT<\/a> #News<\/a>: The Flash Flood<\/span> Warning<\/span> is in effect through 1 p.m. barring any changes to the forecast. Mudflow in the canyon was also detected. CDOT<\/span> crews will continue to assess the burn scar area to determine if it is safe to reopen.
