Mother Nature is sending another mixed bag of weather Maine’s way with the latest storm system placing some areas under a flood watch due to heavy rain, while the foothills face the threat of yet another round of heavy snow.

Twin Cities’ residents should be on the lookout for rising rivers and streams. Meanwhile, neighbors to the north and west can expect to find themselves digging out from under 4 to 8 inches of snow and sleet.

The National Weather Service issued a flood watch Sunday cautioning residents to be on the lookout for possible flooding, with heavy rains and rapidly melting snow dousing southern Maine and New Hampshire. Included in the flood watch area are Androscoggin, Cumberland, Waldo, York, Kennebec, Knox, Lincoln and Sagadahoc counties.

According to the National Weather Service in Gray, between 1 and 2 inches of rain — possibly up to 3 inches in some localized areas — are expected Sunday night and Monday morning. But while rain covers much of southern Maine, snow, sleet and freezing rain are predicted for much of the rest of Maine.

A flood watch means there is a potential for flooding based on current forecasts. Residents living in areas prone to flooding should be prepared to take action should flooding develop.

James Brown, a meteorologist with the National Weather Service, said that some streams and rivers could overflow their banks, and some urban street flooding could occur with backed-up drainage systems. He added that the rapid melting also increases the potential for ice jams that could result in river flooding.

Meanwhile, Oxford and Franklin counties are among the northern Maine counties expecting severe winter weather between Sunday night and late Monday morning. Rain was expected to change over to snow and sleet overnight Sunday for much of northern Maine.
