The U.S. National Hurricane Center is monitoring several disturbances in the Atlantic Ocean and the northeastern Pacific Ocean.
The agency said that the storm could possible re-develop into a tropical storm or depression in the coming days as it approaches the Caribbean Sea.
It said that the storm is producing thunderstorms and gale-force winds in the northern portion of the wave.
No warnings are watches have been issued for the storm.
Sub-Tropical Storm Leslie is “drifting eastward over the central” Atlantic Ocean, and there is “no change in strength,” said the agency in an 11 a.m. update on Sept. 24.
The storm, according to the NHC, is about 1,240 miles west of the Azores Islands and is moving 6 mph to the east. “This general motion is expected to continue through Tuesday night. A turn toward the east-northeast with an increase in forward speed is forecast on Wednesday,” U.S. forecasters say.
“Leslie is forecast to strengthen by mid-week while it interacts and eventually merges with a frontal system,” according to the hurricane center.
No coastal warnings are watches have been issued for the storm.
Disturbance Off East Coast
Hundreds of miles east of Florida, a tropical disturbance with disorganized showers and thunderstorms has a 50 percent chance of forming into a cyclone.
The NHC said that the over the coming days, the system may strengthen as it moves west-northwestward.
However, “upper-level winds” are expected to increase, limiting the storm’s chances for developing even more as it moves near the U.S. East Coast, according to the NHC.
Disturbance South of Mexico
A disturbance 300 miles to the south of Mexico has an 80 percent chance of forming into a tropical cyclone in the next 48 hours, said the NHC.
“Environmental conditions are expected to be conducive for development, and a tropical depression is likely to form within the next day or so while the system moves west-northwestward well off the coast of Mexico,” the NHC stated.
