Hydrologic Outlook issued February 20 at 1:13PM MST by NWS Riverton WY
ESFRIW Low elevation snowpack of around 6 to 12 inches exists across much of the northern portion of the Bighorn Basin including Greybull, Lovell, Powell, and Cody. This snowpack contains an estimated 2 to 4 inches of Snow Water Equivalent (SWE). Temperatures beginning Sunday are expected to climb into the mid 40s to low 50s. The warm temperatures are expected to persist through the middle of next week. 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 Bighorn and Nowood Rivers is

Hydrologic Outlook issued February 20 at 3:25AM MST by NWS Billings MT
ESFBYZ An deep and wet snowpack exists across the forecast area after a record setting February snowfall. 1 to 4 inches of water is locked in this snowpack. Much warmer temperatures forecast over the coming days will increase snowmelt, releasing this water. With the ground 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 increase the potential for ice jam development and may result in additional flooding near waterways. Localized impacts from snowmelt may develop
Flood Watch issued February 20 at 12:38PM MST until February 24 at 2:00PM MST by NWS Missoula MT
* WHAT...Flooding caused by rain and/or snowmelt and/or ice jam is possible. * WHERE...Clearwater and Idaho Counties in Idaho. * WHEN...From Saturday afternoon through Monday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Runoff will increase the risk for rock and mudslides below steep terrain. * ADDITIONAL DETAILS... - An atmospheric river will bring a significant warm up along with widespread rain Saturday into Monday next week (February 24). High temperatures will
