Plateau areas. – Poor drainage, low-lying areas, small streams and

smaller rivers have the highest flood potential. – Current indications are that most areas see just minor

flooding. Moderate flooding possible West Canada Creek

– Persons in flood prone areas in the Upper Mohawk/Tug Hill region should continue to monitor the latest forecasts and be prepared to take action in case more rain falls than is currently expected.

• Winds could be strong enough mainly in the Catskills and Poconos to knock down trees and power lines in scattered localities leading to sporadic power outages.

• Rapidly falling temperatures and a changeover to snow could make for icy road surfaces leading to hazardous travel late afternoon and early evening.
