FLOOD WATCH Issued for Wednesday through Friday!

FLOOD WATCH IN EFFECT FROM WEDNESDAY AFTERNOON THROUGH FRIDAY AFTERNOON!

A slow moving pacific storm system will affect southeast Wyoming and the western Nebraska panhandle from Wednesday afternoon through Friday as it moves across the central and northern Rockies.  The storm system will produce significant rainfall over the lower elevations, with snow above 8500 feet. At this time, 1 to 3 inches of liquid precipitation are possible Wednesday afternoon through Friday. The precipitation and resulting snow melt below 9,000 feet will cause area rivers and streams to rise to at least bank full. Flooding is possible for the lower North Platte River and its tributaries Wednesday afternoon through Friday. The precipitation will taper off over the weekend.

The National Weather Service in Cheyenne has issued a flood watch for Morrill County from Wednesday afternoon through Friday afternoon.

The possibility of flooding will be caused by significant rainfall and additional snowmelt below 9,000 feet over the Sierra Madre and Snowy Ranges. The significant rainfall and mountain snow melt will cause rivers to rise to at least bank full. Additional low land flooding is possible over the area.

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.
