2013-09-17 · near Greystone, Moffat, Colorado

Event narrative

Heavy rainfall on saturated soils led to flash flooding in the Browns Park National Wildlife Refuge, including flood waters that ran into basements of homes.

Wider weather episode

The weather pattern of high pressure over the southeast states and an upper trough along the west coast allowed another surge of monsoonal moisture to move into western Colorado. Cooling temperatures aloft allowed large hail to form in some of the stronger storms, while heavy rain and some flash flooding also occurred.
