 Hurricane Beryl breaking all kinds of records as it plows over the islands of Grenada and St. Vincent and heads towards Jamaica. It has strengthened into a Category 5 storm, the earliest to ever do that. The reason? Water temperature, says ABC Chief Meteorologist Ginger Zee.

But unfortunately, the water temperatures are easily 2 to 4 degrees above average.
