Flash flood watches continue in effect through noon Tuesday in Chenango, Delaware and Otsego counties and through Tuesday night in Schoharie County, the National Weather Service said in alerts this afternoon.
Showers and thunderstorms with heavy rain are expected today and are to continue tonight, the NWS in Binghamton said, with rainfall amounts of 1 to 2 inches with isolated downpours of 2 to 4 inches.
In Schoharie County, which is part of the eastern New York and western New England region, the NWS in Albany estimated rainfall of 1 to 3 inches and isolated amounts of up to 5 inches.
The NWS in Binghamton said with rainfall from the last week, the additional rain could lead to more flooding, with heavy rain causing localized flash flooding of streams and urban and low-lying areas. Rivers that already are running high could flood tonight and Tuesday, the NWS said.
A flood watch means a potential exists for flash flooding, a dangerous situation, the NWS said, and a flash flood warning means that flooding is imminent or occurring.
