MERCER – Residents living near the Sandy River in Mercer were urged Sunday morning to be alert for flooding after an ice jam formed, sending the river over its banks, according to the National Weather Service in Gray.

A Sunday afternoon weather bulletin stated that Saturday’s storm dumped from 1 to 3 inches of rain across the state. Combined with snow melt from warmer than normal temperatures, that created a potential for flooding and dangerous ice jams.

A meteorologist in Gray said late Sunday afternoon that the Mercer jam was the only jam in Maine of which he was aware.

A dispatcher with the Somerset County Emergency Management Agency in Skowhegan said late Sunday afternoon that the river “is dammed up, but we haven’t had any calls of flooding.”

In Rumford and Mexico, the Androscoggin River and Swift River, respectively, were swollen and laden with ice chunks on Sunday, but jams had yet to form.
