Burlington, Vermont – Wind gusts approaching 40 mph will sweep across Lake Champlain through Saturday evening, increasing the risk of ice breakup and shifting floes that could strand anglers and snowmobilers within minutes. Anyone planning to venture onto the lake has a narrow window to reconsider before conditions deteriorate.
According to the National Weather Service in Burlington, strong south winds combined with fluctuating temperatures will weaken ice integrity through the weekend. Afternoon highs are expected to climb well above freezing Saturday before dropping back toward 32 degrees Saturday night, a swing that can fracture and separate ice sheets. The most unstable areas are likely away from protected bays and near inlets, outlets and bridge crossings.
Communities along US-7 from Burlington to Colchester and across the Lake Champlain Islands, including Grand Isle, may notice visible ice movement as winds increase. Boaters and emergency officials warn that open water can expand quickly under persistent gusts, especially in broader sections of the lake. Even ice that appeared solid days ago may no longer support foot traffic.
Anyone near the shoreline should avoid pressure cracks and areas with standing water on the surface. Wear a life jacket, carry ice picks and let someone know your plans before heading out. If ice shifts, move to shore immediately and avoid crossing newly formed seams.
Wind speeds will gradually ease late Sunday, but unstable ice conditions may persist beyond the weekend. Additional safety statements could be issued if winds strengthen or further breakup is observed.
