BILLINGS, Mont. (AP) - Gov. Steve Bullock has declared a flood emergency for the state of Montana after recent snowfall and warm temperatures triggered widespread flooding.
The declaration Monday allows Bullock to mobilize state resources including the National Guard to help with flood response efforts.
Swollen rivers and impassable roads left hundreds of people cut off in rural areas of central Montana.
The Musselshell River near Roundup rose to levels not seen since severe flooding damaged hundreds of homes in 2011.
Authorities warn the flooding could get worse with more rain and snow expected early Tuesday.
Bullocks' office says 30 of Montana's 56 counties are under a flood watch, warning or advisory. The declaration covers the entire state.
