CLEVELAND – The US Coast Guard is urging boaters to stay out of frigid Great Lakes waters this Memorial Day weekend because the water temperatures are colder than normal.

After one of the most brutal winter's Cleveland has experienced in years, water temperatures are taking longer than normal to warm up. Officials say submerging a body can be fatal.

Coast Guard officials say it only takes about 30 minutes for hypothermia to set in and most people can only survive only a couple of hours in the water.

Water temperatures throughout the Great Lakes are ranging between 30 and 50 degrees in many spots. Friday afternoon, the water in the Cleveland Harbor was measured in the mid 50's.

Authorities say water lovers should wait until the temperatures reach approximately 70 degrees before getting in.
