...Appreciable low elevation snowmelt expected over Star Valley
and Jackson Hole Wednesday through Thursday...
...Significant low elevation snowmelt expected across the Upper
Green Basin, Star Valley, and Jackson Hole for Saturday through
The low elevation snowpack across Star Valley and Jackson Hole has
become very ripe or water laden. Afternoon basin temperatures on
Wednesday coupled with rain on Thursday will begin active snowmelt
across Star Valley and Jackson Hole. Even warmer temperatures
on Saturday and Sunday will allow for significant low
elevation snowmelt runoff across lower elevations of the Upper
Green Basin, Star Valley, and Jackson Hole.
Flooding of smaller streams, culverts, and low lying areas
is expected to be the greatest on Sunday as snowmelt runoff
will be peaking at that time.
People living in flood prone areas across the Upper Green Basin,
Star Valley, and Jackson Hole should begin preparing for
rising water across low lying areas such as drainage ditches,
bridges, and basements.
