The National Weather Service has issued a flood watch for much of the region, including Steuben County.
The flood watch will be in effect from 7 p.m. Saturday through 7 a.m. Monday.
A storm developing over the Midwest will push warmer air into the area today, melting the snow cover, according to the National Weather Service. Rain will fall throughout the weekend, and it could be heavy at times, forecasters say.
A high of 51 is expected Saturday, and Sunday's high could be a record 62 degrees.
The combination of heavy rain and snow melt will cause rises in area rivers and streams, forecasters say. There is also a possibility that ice jams will cause more rapid rises in rivers.
There could also be ponding of water on roads and in low-lying areas, so motorists and those who live in flood-prone areas should be alert and monitor weather alerts, according to the NWS.
