ORLANDO, Fla. — A non-tropical low in the north-central Atlantic became our fourth named storm of the 2018 Atlantic hurricane season earlier Tuesday.
- Subtropical Storm Debby forms in North Atlantic
- Should dissipate in a few days; no threat to land
- TRACK THE TROPICS: Watches and warnings, forecast and spaghetti models, satellite loops and more
Debby is a subtropical storm, meaning it has a large, cloud free center and banded thunderstorms well away from the center.
The strong winds are also well removed from the center of circulation, and the storm is more comma shaped than a tropical system that has more symmetry.
Debby is located about 1,190 miles west-northwest of The Azores, with winds sustained at 40 mph as it moves to the north at 13 mph.
Debby is expected to dissipate over the cooler waters of the north Atlantic over the next couple of days.
It is, and will be no threat to land.
Elsewhere in the tropics, the Atlantic basin remains quiet thanks to high amounts of Saharan dust in the upper atmosphere and cooler than average sea surface temperatures.
Strong wind shear over the Caribbean is also keeping activity from developing. In the Eastern Pacific, we are currently watching major category 4 hurricane Hector, potentially brushing the Big Island of Hawaii sometime late tomorrow.
A tropical storm watch is in effect for the Big Island at this time. John, Kristy, and the remnant low of Ileana are following up Hector in a very busy East Pacific basin.
