Lake Effect Snow For Northern New York - Ice Jam Flooding Continues In Vermont








Current Alert Details:
         The National Weather Service in Burlington, Vermont has issued a Flood Advisory for Franklin County for Ice Jams, and Flooding along the Missisquoi River, and its Tributaries from West Swanton to Berkshire. Route 78 & 105 are closed in sections between Berkshire and East Highgate. Also the Pike river in Berkshire is causing some minor Flooding.

         The National Weather Service in Burlington, Vermont has issued a Flood Advisory for Chittenden County for an Ice Jam on the Winooski River. The Ice jam has resulted in flooding on North Williston Rd. At this time North Williston Rd is closed and will remain closed for a while.

         Champlain Valley Weather has issued a Flood Warning for the Missisquoi River in Franklin County, between Berkshire and Highgate. Numerous ice jams have resulted in the partial closure of Route 105 in spots between Berkshire, and Sheldon, and a full closure of Route 78 in East Highgate. Ice jams will likely remain in place for much of the day, especially the one in Highgate. Routes 78 & 105 will continue to be effected much of the day.

         Champlain Valley Weather has issued a Flood Warning for the Winooski River in Chittenden County. Ice jams have been reported between Westford, and Williston. These Ice jams have resulted in Water overflowing onto North Williston Rd. These ice jams will likely continue to effect areas between Westford and Williston for much of the day.

         Champlain Valley Weather has issued a Flood Watch for the Northern Half of Vermont, and Clinton County in Northeastern New York for the potential of Ice Jam Flooding. The Counties under the watch have the highest threat of ice jam flooding. Already numerous ice jams have been reported on area waterways, most at this time are not producing any flooding, but could with short notice. Additional ice jams are likely today as water levels change.

         Champlain Valley Weather has issued a Lake Effect Snow Advisory for portions of Southeastern St. Lawrence County. Period of Lake effect snow will result in snow accumulations of 3-6 inches by late tonight. Snow will be locally heavy, and visibilities will be reduced to less then a half mile in the heaviest snow.


Champlain Valley Weather Discussion:
         Things continue to be busy across the area today. Significant ice jams have developed on many rivers, and streams. Many of them are not producing flooding at this time, but could produce flooding later today. Thus I have continued the Flood Watch for areas most likely to witness any ice jam flooding. The worst of the current ice jam flooding is across Franklin and Chittenden counties in Northwestern Vermont. Route 78 & 105 are closed in spots from Berkshire to East Highgate. There is some concern that ice jam flooding may occur further down stream towards West Swanton later this afternoon, as another ice jam has been reported along that stretch of the Missisquoi River. Luckily though now additional significant rain will occur. Only light snow/ rain showers will occur today across much of the region.

         In portions of Northern New York though, its a different story. Across southern portions of St. Lawrence county significant accumulations of lake effect snow are likely to occur. Thus I have issued a Lake Effect Snow Advisory for 3-6 inches of snow. The heaviest accumulations will likely occur from Star Lake to Wanakena to Cranberry Lake.

         Stay tuned for any further updates.
