MASON CITY, Iowa — Authorities say about 100 apartment residents are being evacuated from two complexes in northern Iowa’s Mason City.

The city said in a news release Thursday that an emergency shelter had been set up on the west side of the Cerro Gordo County community. County emergency management spokesman Michael Groesbeck says Chelsea Creek has left its banks, forcing the evacuations.

The National Weather Service says more than 2½ inches of rain has fallen in the past 12 hours at Mason City and more is in the forecast. The Winnebago River sits 2 feet over flood stage of 10 feet and is expected to crest at 14.2 feet early Friday morning, near the top of the dike on the north side of Mason City.
