ORLANDO, Fla. — Our fifth named storm of the 2018 Atlantic hurricane season has formed, but it is no threat to Florida.

Subtropical Storm Ernesto is currently located in the north-central Atlantic, about 630 miles southeast of Cape Race, Newfoundland.

This system has sustained winds of 40 mph and is moving north-northeast at 10 mph. We may see slight strengthening overnight, but Ernesto will move over cooler waters late Thursday or early Friday and weaken quickly. No threat to land.

Subtropical systems differ from true tropical systems because of their composition, but the impacts are the same. When the strongest winds are displaced from the cloud-free center of low pressure, it is considered subtropical. Once the core of stronger winds and thunderstorms are focused around the storm’s center, it classified as tropical.  

Also in the southern Atlantic, a strong tropical wave located about 850 miles east-southeast of the Windward Islands now has a low chance for tropical formation over the next five days.

Conditions may be conducive enough for development as this wave moves west. However, once it enters the eastern Caribbean Sea, strong upper level winds will limit strengthening and may completely tear it apart.

Models at this point do not show much with this system, so no big concerns needed at this time.

Hurricane season runs through Nov. 30.
