Flooding is "a growing concern for early next week" because of runoff from melting snow and possible moderate to heavy rain, the National Weather Service said this afternoon.
Many areas in northeast Indiana and northwest Ohio received 5 to 12 inches of very wet snow Tuesday night, which is expected to slowly melt through the weekend, the weather service's northern Indiana office said in a statement.
The ground is already moist and nearly saturated, the statement said.
Meanwhile, a slow-moving low-pressure area will approach the region Sunday, with a slow-moving cold front in the area through Monday, the weather service said. Several upper-air disturbances will be possible, it said, each bringing a soaking rain, and rain amounts could exceed 1 to 2 inches by the end of Tuesday.
If 1 inch of rain falls, flooding would develop in low-lying areas, the weather service said. If rain approaches or exceeds 2 inches, it said, significant flooding could develop.
The weather service encouraged area residents to seek updated forecasts throughout the weekend, listen for watches and warnings next week and begin thinking about preparations if you live in flood-prone areas.
