Yesterday saw two very different setups between the eastern and western halves of the state, with the Continental Divide<\/span> acting as a barrier between the plume of monsoonal moisture advecting into the state. There was widespread<\/span> thunderstorm activity in the west, compared to hot and dry conditions to the east. The extra monsoonal moisture that flowed into Northern and Central Mountains helped to moderate fire behavior on the Morgan Creek, Sylvan, and Muddy Slide fires with higher humidity and chances for wetting rains from thunderstorms. However, heavy rains also resulted in floods in the Poudre Canyon, Glenwood Canyon, and near Telluride.<\/p>\n Flash flood<\/span> warnings were issued for the Poudre Canyon after Doppler radar indicated heavy rainfall, and the canyon was evacuated yesterday evening<\/a>. Up to 1 inch of rain fell in just half an hour over the Cameron Peak burn scar, resulting in rapid, deadly debris flow and runoff into the Cachle la Poudre River. Kylie Bearse shared the following video on twitter showing the fast-moving river – debris and ash from the burn scar cause the river to look black. Highway 14 remains closed from Rustic to Cameron Pass.<\/p>\n Nearly an inch of rain in 30 minutes last night caused this flash flood<\/span> in the Poudre Canyon – Another Flash Flood<\/span> Watch<\/span> in effect for the area today #cowx<\/a> Video from Wayne Couch #cowx<\/a> pic.twitter.com\/TbuhwzLBuF<\/a><\/p>\n — Kylie Bearse (@KylieBearseWX) July 21, 2021<\/a><\/p><\/blockquote>\n\n
