BURLINGTON, Vt. - As moderate to heavy rainfall moves into the area today, the National Weather Service has posted a flood watch for all of northern New York except the St. Lawrence River valley.
The Weather Service's Burlington office said heavy rain will develop this evening and continue into Friday morning.
Forecasters are calling for 2 to 3 inches of rain over the Adirondacks, while some isolated areas could see 4 inches or more. Other areas of northern New York and Vermont could get 1.5 to 2.5 inches of rain.
"Some localized flash flooding is possible in thunderstorms," the Weather Service said in a statement. "Heavy rainfall this past month has saturated soils, and rivers and streams are running well above normal. The wet conditions coupled with additional rainfall are responsible for the flood threat."
Small rivers and streams will see sharp rises at the onset of the heavy rain, the Weather Service said. Some main rivers could approach or exceed their banks, and areas that have seen flash flooding over the last few weeks could be vulnerable to more flooding.
The heavy rain could also wash out roads and culverts, produce some localized landslides or further damage roads that were already damaged by flooding earlier this week.
The Weather Service said people should monitor forecasts and be alart for flood warnings. Those who live in flood-prone areas are encouraged to be prepared to take action and to stay away from rising flood waters.
