In north central Wyoming, Sheridan.* From late Tuesday night through Saturday morning* Widespread rain and mountain snow will fall across the region this week. Heavier periods of precipitation are expected Tuesday through Wednesday and again Thursday afternoon into Friday.* Soil conditions are very moist and additional rainfall will cause strong rises on creeks and streams. Areas prone to ponding will fill with water and begin to spread into adjoining areas.* Flooding is not expected on the Yellowstone River as snowmelt is significantly diminished and the river has plenty of room to handle runoff from the rain.* Rural non paved roads may become impassable in low spots due to slick conditions and water crossing the roads. Travelers will want to monitor highway information should sufficient rain fall to impact larger paved roadways.
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.
