Special Weather Statement issued May 16 at 4:33AM EDT by NWS Burlington VT

Effective: Sat May 16, 2026, 4:33 AM
Expires: Sat May 16, 2026, 5:00 PM

...Please check with state and local authorities regarding guidelines for allowed activities... * The warm air temperatures this weekend in the mid 70s may cause people to underestimate the dangers of the cold water temperatures which are currently only in the mid 40s to mid 50s across Lake Champlain and the smaller lakes and rivers. * The cold water temperatures can quickly cause hypothermia to anyone immersed in the water. According to the US Coast Guard, when the water temperatures are below 50 degrees, the chance of immediate incapacitation due to cold shock is extremely high. Anyone on small boats, canoes or kayaks should plan accordingly if recreating this weekend and use extreme caution to avoid this threat. Paddle smart from the start and always wear your life jacket! * Strong winds are also expected this weekend with gusts 20 to 30 mph from the south. If boating on large bodies of water, these strong winds can increase the likelihood of overturning your boat,canoe or kayak due to increased wave heights. * Due to recent rain, area rivers continue to run fast with swift water currents. The swift water can easily overturn a kayak or canoe into the frigid river waters. Once in the cold water, the strong currents will make it difficult to reach safety.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
