Great Falls, Montana – Flash flooding remains a concern across North-central and Central Montana as saturated soils face days of renewed heavy rain and thunderstorms through Saturday night. Urban neighborhoods, burn scars, and low-lying roadways are especially at risk for rapid flooding as storms move slowly and dump more rainfall onto ground that can’t absorb it.
According to the National Weather Service in Great Falls, a Marginal Risk for excessive rainfall continues through Saturday, with the Weather Prediction Center noting a 5% chance for flash flooding within 25 miles of affected areas. Counties under heightened alert include Cascade, Chouteau, Fergus, Hill, Judith Basin, Liberty, Meagher, Pondera, Teton, Toole, Valley, Wheatland, and Yellowstone.
City crews in Great Falls, Lewistown, and Havre are bracing for possible water on roadways and fast-rising creeks. Rural areas with burn scars and poor drainage could see water rise quickly, especially under the heaviest downpours. Residents are urged to avoid driving through flooded streets, keep cell phones charged, and prepare to move to higher ground if needed.
With soil moisture levels well above normal from previous storms, even moderate rain could push creeks and streams over their banks for short periods. Local law enforcement and the National Weather Service are asking for flood reports to help direct resources.
Showers and thunderstorms will continue to threaten the region into Saturday night. More advisories or warnings could follow as the weather pattern evolves.
