JACKSON HOLE, WYO – Sublette County Emergency Management has asked Buckrail to pass along the following broadcast bulletin.
A National Weather Service Flood Watch is in effect until Thursday afternoon for portions of NW Wyoming, SW Wyoming, and west central Wyoming, including the following areas, in NW Wyoming, Jackson Hole. In SW Wyoming, South Lincoln County. In west central Wyoming, Star Valley, Upper Green River Basin, and Upper Green River Basin Foothills.
Three- to six-tenths of an inch of rain is expected across the western valleys Wednesday
afternoon through early evening. The rain is expected to turn to snow by early Thursday morning.
The rain on a very ripe and melting snowpack will result in rapid snowmelt runoff. Additional flooding is expected Wednesday evening through early Thursday afternoon.
Portions of Sublette County could be most vulnerable to additional precipitation as flooding in parts that county has already been a concern. The Bear River near Cokeville is running near bankfull and is expected to flow near bankfull stage through Thursday morning.
A Flood Watch means there is potential for flooding based on current forecasts. People living in flood prone areas across the western valleys and across the Upper Green Basin should begin preparing for rising water across low lying areas such as drainage ditches, bridges, and basements. You should monitor later forecasts and be alert for possible Flood Warnings.
