BILLINGS, Mont. (AP) — Officials have closed a section of Interstate 90 in Montana due to surging water from the Bighorn River as authorities on Sunday continue to deal with rising water in the eastern part of the state where a slow moving storm dumped up to six inches of rain.

Meteorologists with the National Weather Service on Sunday blanketed much of eastern Montana with flood warnings as the storm begins moving out of area but runoff works its way through streams and rivers.

Meteorologist Keith Meier in Billings says attention is now turning to larger rivers that run through more populated areas.

He says the Yellowstone River at Miles City is expected to crest about 3 feet above flood stage on Monday.

Eastern Montana authorities are also warning motorists of flash floods.
