Florida could see wind, rain from what may become Tropical Storm Isaias by week’s end, NHC says

The National Hurricane Center has yet to name a churning system in the Atlantic, but issued its first two advisories for Potential Tropical Cyclone Nine, which is projected to spin up and become Tropical Storm Isaias Tuesday night or Wednesday morning.

While Florida is still in the forecast cone, the NHC said details of the long-range track remain unclear because of a lack of a defined center.

“However, this system could bring some rainfall and wind impacts to portions of Hispaniola, Cuba, the Bahamas, and Florida by the end of the week,” the NHC said. “Interests there should monitor its progress and updates to the forecast over the next few days.”

The 5 p.m. advisory included a tropical storm warning for the northern coast of the Dominican Republic. Earlier Tuesday tropical storm warnings were issued for Puerto Rico, the U.S. Virgin Islands, British Virgin Islands, Antigua, Barbuda, Montserrat, St. Kitts and Nevis, Guadeloupe, Martinique, St. Martin/St. Maarten, Saba, St. Eustatius and Dominica.

The NHC expects those areas could experience tropical storm conditions by the end of Wednesday.

Flash flooding and mudslides could be experienced in the Leeward Islands, the Virgin Islands and Puerto Rico. The NHC asked those in the cone to focus not on the details of the storm’s track as rainfall and wind hazards will extend far from the center of the system.

“The forecast track and intensity is also more uncertain than usual, particularly after the system moves near Puerto Rico,” the NHC said.

Florida could be seeing landfall on its current projected path somewhere near Broward County by Sunday morning, according to FOX 35 meteorologist Jayme King. However, most projections show the storm weakening long before it hits South Florida.

“The proposed track has this thing rolling over the Hispaniola mountains. We’ve seen that in the past where the mountains shred storms down to nothing,” King said.

A stretch of dry air lingering from the African Saharan dust layer could also play a role in diminishing the storm’s strength. Before that takes place however, meteorologists are expecting to see the development of Tropical Storm Isaias by Tuesday night.

”Early stages means there is greater than average uncertainty in the track and intensity,” King said. “The bottom line is again it is hurricane season and you need to be prepared for this.”

The storm is moving at 23 mph with maximum sustained winds of 40 mph and is about 435 miles east-southeast of the Leeward Islands, the NHC said in its 5 p.m. update. Environmental conditions have it strengthening over the next 48 hours before it interacts with Caribbean islands.
