Add central Minnesota to the snow-packed regions where forecasters are warning of possible spring flooding.

The National Weather Service says the flood threat has risen in the past two weeks as snow on the ground increased to near historic highs. The weather service’s warning came even as two more significant snowstorms are in the region’s forecast into next week.

The weather service estimates at least a 50 percent chance of major flood stage on the Minnesota River.

The weather service says flooding depends on how fast the snow melts.
