The National Hurricane Center (NHC) says, “The system is expected to form a tropical storm on Wednesday near Howard Island.”
It issued tropical storm warnings for Puerto Rico, the Howard Islands and the Virgin Islands.
A tropical storm watch was issued for the Dominican Republic, from Haiti with Cabo Angano to the northern border.
The storm that arrived late Tuesday morning was located 585 miles east-southeast of Howard Island and was moving west at a speed of about 23 mph.
It will affect the Leeward Islands until Wednesday and Puerto Rico by Wednesday night.
It is already delivering a tropical storm wind of 40 mph that extends 230 miles out from the center of the storm system. The intensity of the winds is expected to increase.
3 to 6 inches of rain is expected, with locally increasing to 10 inches in the next few days in the Howard Islands, Virgin Islands and Puerto Rico. Heavy rains may increase flooding and torrential brightness.
Why is it called Potential Tropical Cyclone Nine?
It is not yet a tropical storm. CNN meteorologist Chad Myers says the cause is “a possible tropical cyclone nine”, which is not the period of the storm’s circulation. Instead, it is too long. “When a circular center is formed at the end, that is when it will be called a tropical storm.”
Calling it a potential tropical cyclone, it allows countries to issue warnings.
Once it is named Isis – pronounced (ees-ah-EE-as) – it will be the earliest storm to begin with an “I” on record. The previous record was set on 7 August 2005, which was part of the busiest season ever.
There is uncertainty as to where and how strong the storm will be near Florida.
Even though the storm will not be a land hazard for a few days, the models are consistent in harnessing and strengthening the storm in hot water.
“Hardly you see the model with such a storm as you are seeing,” said Myers. “There is a general consensus that the storm is going to do something and it is going to hit the Bahamas region.”
But how it interacts on Howard Island and Hispaniola can affect the intensity of the storm.
Hapaniola, the Bahamas, Cuba and Florida should continue to monitor forecasts as both track and intensity changes are likely, NHO says.
“It cannot be adequately emphasized that since the system is still in its early stages, the uncertainty over average is about both short-term and long-term track and intensity forecasts,” NHC said.
