Road to Route 37c in the town of Bombay is closed in both
directions due to the flooding. Other flooded roads include St.
Regis, gray, north, church, and mill streets

* ice jams are very unpredictable and can break up, move and jam
again very quickly. Water backing up behind the jam is the main
flood threat, and can flood areas under deep water with
surprising speed. Favored ice jam locations are where a river
bends or slows, at bridge abutments, or Near Islands, sand bars,
and other obstructions to river flow.

* Some locations that will experience flooding include...
St. Regis, Helena and Hogansburg.

Precautionary/preparedness actions...

River levels may fluctuate rapidly due to ice with little or no
warning. Residents in low lying flood prone areas should remain alert
for possible flooding due to ice jams. Ice jam flooding can be very
localized and not affect all locations along the river as in a
typical river flood.
