A storm system will bring rain to the Jackson Valley, the Star
Valley, and southern Lincoln county starting Monday night, and
continuing through Tuesday evening. The rain will change over to
all snow late Tuesday evening. New rainfall predictions now range
from one half inch to around one inch in the
western valleys and southern Lincoln county. Snow levels will be
mainly above 8000 feet Monday night through Tuesday, then lower to
the valley floors Tuesday evening.
FLOOD WATCH IN EFFECT FROM LATE TONIGHT THROUGH WEDNESDAY MORNING
The National Weather Service in Riverton has issued a
* Flood Watch for portions of northwest Wyoming, southwest
  Wyoming, and west central Wyoming, including the following
  areas, in northwest Wyoming, Jackson Hole. In southwest
  Wyoming, South Lincoln County. In west central Wyoming, Star
  Valley.
* From late tonight through Wednesday morning
* New rainfall predictions now range from one half inch (0.50")
  to around one inch (1.00") in the western valleys and southern
  Lincoln county. Snow levels will be mainly above 8000 feet
  Monday night through Tuesday, then lower to the valley floors
  Tuesday evening.
* The likelihood of rain over a melting low elevation snowpack
  certainly will increase the potential for flooding of low lying
  areas on Tuesday into Wednesday. The ground may be frozen in
  some locations, or already saturated. Thus, there is a greater
  chance of overland flow and sheet flooding with a more rapid
  snowmelt. Low lying areas could be quickly inundated with
  water. Significant standing water may remain a problem through
  late this week.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Flood Watch means there is a potential for flooding based on
current forecasts.
You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
