Air temperatures will rise primarily into the lower 70s to lower to middle 80s across the Tri-State area on Sunday. However, water temperatures remain in the 50s. 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 lose 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. Several things to consider. * Always wear a life jacket. * Dress for the water temperatures, not air temperatures. Wear cold water protection, like a wetsuit or drysuit. * Carry an Emergency Position Indication Radio Device. * File a float plan with someone you trust. * Check the latest marine weather forecast, including water temperatures at www.weather.gov/okx/marine before you go out on the waters. Your ability to survive cold water immersion depends on your ability to stay afloat and stay warm until help arrives.
