MISSOULA, Mont. – Western Montana’s Clark Fork River has reached major flooding stage for only the sixth time since measurements have been taken.
National Weather Service meteorologist Alex Lukinbeal said Thursday that the still-rising river is threatening additional residences two days after Missoula County authorities ordered the evacuation of 60 homes.
Lukinbeal says the river has surpassed 13 feet. The last time it reached that major flood stage was in 1981.
Forecasters expect the river to crest over the weekend at 13 ½ feet, which would be the third-highest level ever recorded. The river is then expected to drop and rise around that major flood level through next week.
Lukinbeal says major and moderate flooding could go on for weeks, giving the river a long period to damage homes and structures in the Missoula area.
