Tropical Storm Ernesto spun over a warm section of the Atlantic today and gathered strength that one forecaster said could return it to hurricane strength–if only briefly.

Michael Schlacter, chief meteorologist at Weather 2000, a meteorological consulting firm in New York, noted that Ernesto's track took it over the Gulf Stream in the Atlantic, where the water temperature exceeded 82 degrees Fahrenheit.

“Hurricanes and tropical storms love warm waters,” he said, noting that “anything greater than 80 degrees is supportive of a hurricane.”
