Tropical Storm Nadine could strengthen over the next few days while Tropical Storm Miriam is expected to lose some punch, U.S. weather forecasters said.
No watches or warnings were posted for either storm, the National Hurricane Center in Miami said in its 5 a.m. EDT advisory.
Nadine, with maximum sustained winds of 45 mph, was about 530 miles south-southwest of the Azores Islands, moving on a south-southwesterly track at 5 mph in the Atlantic Ocean, forecasters said.
Nadine could strengthen during the next 48 hours and was expected to shift toward the southwest or west by late Thursday, the hurricane center said.
Tropical storm force winds extended outward from center up to 115 miles.
In the Pacific Ocean, Tropical Storm Miriam, with maximum sustained winds of 70 mph, was about 430 miles west-southwest of the southern tip of Baja California, Mexico, traveling northwest at 6 mph.
Miriam was expected to weaken during the next couple of days, forecasters said, shifting more to the north-northwest or north later Wednesday.
Tropical storm force winds extended outward from center up to 105 miles.
Swells generated by Miriam will affect the southern and western coasts of southern and central Baja Peninsula for the next few days, forecasters said, the swells likely could cause life-threatening surf and rip current conditions.
