PORT LEYDEN A part of Leyden Road has been washed out and the Lewis County 911 Center and area residents have reported serious flash flooding near Constableville, Port Leyden and Lyons Falls, the National Weather Service said.
In Turin, boat rescues have been reported, the weather service said.
Three to five inches of rain have fallen over the area since 2 p.m., as a result of slow-moving thunderstorms developing and redeveloping over the area. Small hail and wind gusts up to 40 mph have also been reported.
Some areas may have received more than seven inches, according to Doppler radar estimates.
An additional half-inch of rain is possible tonight. A flash flood warning is in effect for southern Lewis County until 8:15 p.m.
Lewis County Sheriff Michael P. Carpinelli issued a travel advisory for the southern part of the county, as of 5 p.m., due to flooding and washed-out roads. The advisory is in effect until further notice.
Excessive runoff from heavy rainfall will cause flooding of small creeks and streams, the weather service said.
The service warns people not to attempt to travel across flooded roads and to seek alternative routes, as only a few inches of flowing water can carry a vehicle away.
