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
