* Today's warm air temperatures in the 70s and lower 80s may cause people to underestimate the dangers of the cold water temperatures which are currently only in the lower 60s across Sebago Lake and Lake Winnipesaukee, and in the 50s in the region's smaller lakes and rivers. * The cold water temperatures can quickly cause hypothermia to anyone immersed in the water. When the water temperature is below 60 degrees, the average submerged person could loose dexterity within minutes and be unable to accomplish simple tasks. 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!
