Flooding Rains Possible in Montana and Idaho

12 Jun 2017, 1:39 pm

Heavy rain from strong thunderstorms is a concern over the next 24 hours in portions of Montana and Idaho. A Flash Flood Watch has been issued for most of Western Montana and in the high country of Idaho, including most of Yellowstone National Park. Rainfall totals of 1″ to 3″ are possible through Tuesday, which could produce flooding problems.

The National Weather Service says the heavy rain may create rapidly rising rivers and streams that could produce flooding. Rock slides and mud slides may occur in favored canyons and over mountain passes. Standing water could become deep on agricultural lands and in low lying areas. Ponding of water on roads and flooded or washed out roads may create impassable conditions for a period of time.

A slow moving low pressure center will drift northward from Utah into Idaho and Wyoming tonight. Areas of heavy rain are likely, even some snow in the highest elevations. The storm will weaken, but a trough will still create thunderstorms into Tuesday. The rain will begin to lift out of Western Montana Tuesday night.
