7 Route 5 between Coventry and Newport will be flooded.
6 Flood waters reach edge of Route 5 between Coventry and Newport. During heavy rain/flash flood event use 6 ft as guidance threshold for flood warning (ALBFFWBTV) for Orleans County. During slow rises such as snowmelt only, water approaches road and 6 ft stage alone should not be criteria for warning issuance.
5 Field flooding occurs along Route 14 between Albany and Irasburg.
