Meanwhile, it will strike Puerto Rico on Wednesday night into Thursday.
Currently, it is delivering tropical-storm-force winds of 40 mph that extend 230 miles outward from the center of the storm system. The winds are forecasted to increase in intensity.
According to the report, it is likely to produce rainfall amounts of 3 to 6 inches.
It is likely to expect up to 10 inches rainfall over the next few days.
This can occur across the Leeward Islands, Virgin Islands and Puerto Rico.
The report said, this could lead to flash flooding and mudslides.
Potential Tropical Cyclone Nine
Currently, it is considered a Potential Tropical Cyclone Nine.
Authorities said, it is not a tropical storm quite yet.
Hence, is still called “Potential Tropical Cyclone Nine.”
CNN meteorologist, Chad Myers, said is the storm does not have a round center of circulation.
Rather than a round center, it has elongated shape.
“When a circular center finally forms, that is when it will be called a tropical storm,” he added.

When it becomes a tropical storm it will be named “Isaias.”
According to authorities, it will be the earliest storm to begin with an “I” on record.
