Hydrologic Outlook issued February 26 at 12:40PM MST by NWS Riverton WY
ESFRIW Low elevation snowpack of around 2 to 8 inches exists across much of the northern portion of the Bighorn Basin including mountain foothills. This snowpack contains an estimated 1 to 3 inches of Snow Water Equivalent (SWE). Warmer temperatures occur Thursday through Sunday with highs nearing or exceeding 50 degrees (Feb 27 - Mar 2). The upcoming warm temperatures, combined with the low elevation snowpack, could result in 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.
