A system of severe storms that produced a tornado outside Billings on Monday night has caused concern for flooding in northeastern Montana, according to the National Weather Service.

One of several storm cells to pass through the area on Monday night produced a tornado that was seen touching down twice, once two miles north of Laurel at 8:24 p.m. and again near Worden at 10:04 p.m.

The storm produced hail over an inch in diameter. Meteorologist Ryan Leach said one house and a grain silo were damaged in the storm.

Concerns have shifted from severe storm conditions to potential flooding in Musselshell, Golden Valley and Wheatland counties on Tuesday.

"Today we are going to have scattered showers across the area," Leach said. "Quite a bit of it is north of Billings in Broadview and Roundup."

All of those areas were just starting to recover after weeks of flooding following previous rain storms. Leach said another 2 to 4 inches has fallen over the area since last night, and continues to fall.

The Musselshell at Roundup was last flowing at 9.8 feet, just below the flood stage of 10 feet.

Leach said the weather service is going to do another river forecast on Wednesday morning to determine if the area's flood watch should be upgraded to a flood warning.

"As far as snowmelt and stuff like that, the river is forecasted to go down, but with all the rain up there, it's taken a turn," Leach said. "We will have to look at that very closely this morning."
