The National Hurricane Center in Miami said in its 11 p.m. EDT advisory Nadine had maximum sustained winds of 70 mph with higher gusts and was expected to become a hurricane Thursday morning. The storm was centered 820 miles east-northeast of the Lesser Antilles and heading northwest at 16 mph, the center said.
Nadine, which was producing tropical storm-force winds outward as far as 115 miles, was far enough out to sea that no coastal watches or warning were warranted, the forecasters said.
Nadine was expected to turn to the north-northwest by Thursday night or Friday morning.
Kristy was spitting out 50 mph winds as it headed west-northwest at 9 mph about 200 miles southwest of Cabo Corrientes, Mexico, and about 375 miles south-southeast of the southern tip of Baja California, Mexico, in the Pacific.
No coastal watches or warnings were in effect for Kristy, which was expected to stay on a northwest to west-northwest track for the next couple of days that would take it away from the Mexican coast, but the storm was sending bands of rain over portions of the southwestern coast.
Kristy was producing tropical storm winds outward as far as 80 miles from its center. The storm was expected to pick up some strength in the coming days.
