River Statement
Issued By NWS Riverton WY
Issuing Time Thu, 20 Feb 2025 12:13:00 PST
Broadcast Time Thu, 20 Feb 2025 12:13:00 PST
Valid Until Fri, 21 Feb 2025 16:00:00 PST
Brief Description Hydrologic Outlook
Detailed Description 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 possible as well, and could lead to ice jamming and potential resultant flooding. Similar snowpack also exists across portions of northern Johnson County. Although the risk for ice jams is lower, ponding of water and overland runoff could fill culverts and other low-lying areas. Now would be the time to clear snow, ice, and debris from culverts and other flow paths to allow runoff to flow away from buildings and other vulnerable infrastructure. This could include moving deep snow away from the foundations of buildings, relocating equipment to higher ground, and moving livestock out of poorly drained or low- lying areas. Stay tuned for the latest river forecasts.
