Continued warm temperatures forecast over the coming days will accelerate snowmelt, releasing this water. With the ground still frozen, water will not be able to soak in and will run off. Water flowing overland and accumulating in low lying areas may result in localized flooding. Water flowing into creeks and streams will

ESFRIW Low elevation snowpack of around 4 to 10 inches exists across much of the northern portion of the Bighorn Basin including Greybull, Lovell, Powell, and Cody. This snowpack contains an estimated 1 to 3 inches of Snow Water Equivalent (SWE). Temperatures beginning are expected to climb into the low 40s to near 50 degrees each afternoon through next weekend. Warmest temperatures look to occur Friday through Sunday (Feb 28 - Mar 2). The warm temperatures, combined with the significant low elevation snowpack, could result in significant melting and injection into local rivers and streams. Ice break up on the
