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.
