Air temperatures will rise into 70s this afternoon. However, water temperatures remain in the 50s. The cold water temperatures can quickly cause hypothermia and physical incapacitation to anyone suddenly 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 going out on small boats, canoes or kayaks should plan accordingly 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. $$  747 WHUS54 KMOB 250651 SMWMOB GMZ670-250815- /O.NEW.KMOB.MA.W.0039.260525T0651Z-260525T0815Z/ BULLETIN - IMMEDIATE BROADCAST REQUESTED Special Marine Warning National Weather Service Mobile AL 151 AM CDT Mon May 25 2026 The National Weather Service in Mobile has issued a * Special Marine Warning for...
