“The system is expected to become a tropical storm when it hits the Leeward Islands on Wednesday,” the National Hurricane Center (NHC) said.
This has led to tropical storm warnings being issued to Puerto Rico, Leeward Islands and the Virgin Islands.
The Dominican Republic was issued a tropical storm watch from Cabo Engano to the northern border with Haiti.
A late Tuesday morning storm was 585 miles east-southeast of the Leeward Islands and ran west at about 23 miles per hour.
It will affect the Leeward Islands until Wednesday, and Puerto Rico from Wednesday evening to Thursday.
It already provides 40 miles per hour of tropical storm force winds that extend 230 miles outward from the center of the storm system. Wind strength is forecast.
Rainfall islands, the Virgin Islands, and Puerto Rico are expected to range from 3 to 6 inches over the next few days. Locations are provided up to 10 inches. Heavy rain can cause flares and mudguards.
Why it is called the potential tropical cyclone Nine
This is not yet a tropical storm. The reason it is called the Ninth Tropical Cyclone is because the storm does not have a center of circular circulation, says CNN meteorologist Chad Myers. Instead, it is very elongated. “When a circular center is finally formed, that will be when it will be called a tropical storm.”
Calling it a potential tropical cyclone, it allows countries to issue warnings.
When given the name Isaias – assumed (ees-ah-EE-as) – it will be the earliest storm to begin with the recorded “I”. The previous record was set in 2005. August 7
Near Florida, it is unknown where and how strong the storm will be
While the storm won’t threaten drought for a few days, the models consistently demonstrate a storm flowing into warm waters and intensifying.
“You rarely see models like you see converging with another storm,” Myers said. “It is therefore agreed that the storm will do something and that it will enter that territory of the Bahamas.”
However, how it interacts with the Leeward Islands and Hispaniola may affect the intensity of the storm.
Spain, the Bahamas, Cuba and Florida should continue to monitor forecasts as changes in the route and intensity are likely, the NHC says.
“It cannot be stressed enough that as the system is still in its infancy, there is higher than average uncertainty in both short-term and long-term route and intensity forecasts,” the NHC said.
