CHEYENNE, Wyo. (AP) — The National Weather Service has posted a flash flood watch for parts of central and southeast Wyoming.

Flash flood watches are in effect for areas of the upper Wind River Basin and the southern half of the Absaroka Mountains in central Wyoming as well as the Snowy and southern Laramie ranges in southeast Wyoming.

The weather service says rain shows and isolated thunderstorms on Thursday can be expected to produce moderate to heavy rain in already saturated areas. Additional rainfall amounts of 1 to 2 inches is possible.

The rain could cause flash flooding along small streams and some road areas. Rock and mud slides are possible in the mountains.
