SAGINAW, MI — Heavy rains in Mid-Michigan since Sunday have sparked flood warnings and forecasts of minor river flooding.

The National Weather Service issued a flood warning Tuesday morning, Oct. 24, for Isabella, Clare and parts of Arenac counties. Roscommon, Ogemaw, Gladwin and Iosco counties are under a flood watch.

Isabella County has seen just shy of 4 inches of rainfall as of Tuesday morning and is warning drivers of water over roads in many areas. MBS International Airport recorded just under 2 inches of rain, and Flint’s Bishop Airport had 0.41 inches, according to the National Weather Service.

“With the amount of rain that has fallen, and the flooding earlier in the year, there is no way to know if a road is still intact underneath flood waters,” Isabella County Dispatch personnel wrote in a Facebook post. “Please remember to ‘Turn around, don’t drown.'”

The National Weather Service said another inch of rain throughout Tuesday is expected.

Main rivers in Arenac, Isabella and Saginaw counties are expected to peak at minor flood stage on Wednesday.
