Two tropical systems are churning through the Atlantic Ocean and Caribbean Sea in the weeks leading up to the climatological peak of the hurricane season: Tropical Storm Dorian and Tropical Depression Six.
Tropical Storm Dorian was moving through the Windward Islands Tuesday morning, and as of the 11 am advisory from the National Hurricane Center, was producing winds up to 50 mph. A Hurricane Watch has been issued for Puerto Rico and the eastern third of the Dominican Republic.
Dorian is forecast to be near or just below hurricane strength when it moves close to Puerto Rico and eastern Hispaniola Wednesday into Thursday morning. Thereafter, forecasters have expressed “considerable uncertainty” on the track and strength of the season’s fourth tropical storm. Potential interactions with land, and the extent to which Dorian’s structure may be affected, are difficult to ascertain with any confidence at this point.
If the tropical storm survives or avoids the high terrain of Hispaniola and Puerto Rico, it may strengthen and move toward Florida over the upcoming holiday weekend. At this time; however, it’s likely that Dorian will stay south of the Palmetto State.
Tropical Depression Six is roughly midway between Bermuda and the North Carolina coast. It is forecast to become Tropical Storm Erin early Wednesday based on the midday Tuesday forecast from the National Hurricane Center. A front moving off the eastern seaboard is expected to carry the developing tropical storm away from the east coast of the United States. It may; however, move over the Canadian Maritime provinces Friday and Saturday.
