Tropical storm forecast to 'rapidly' intensify into major hurricane
Tropical Storm Helene was expected to "rapidly" strengthen and grow in size as it moved on Wednesday into the Gulf of Mexico, U.S. weather officials said.
The storm as of about 4 a.m. local time had maximum sustained winds of about 65 mph, the National Hurricane Center said. It was expected to intensify into a hurricane on Wednesday, before further strengthening into a "major" hurricane on Thursday, the center said.
Helene early Wednesday was traveling northwest at about 9 mph, the center said.
"On the forecast track, the center of Helene will pass near the northeastern coast of the Yucatan Peninsula this morning, move across the eastern Gulf of Mexico on later today and Thursday, and reach the Big Bend coast of Florida late Thursday," the center said.
