Tropics May Threaten Eastern Caribbean Next Week
Residents and travelers to the Caribbean should be on high alert next week for potential tropical development.
We are not referring to Tropical Storm Fiona that sits alone over the Atlantic Ocean’s open waters, rather, we are referring to two tropical waves over the central and eastern Atlantic.
Tropical Storm Fiona will encounter wind shear that will likely weaken the storm to a remnant low this weekend.
Southeast of Fiona sits two tropical waves; one over the central Atlantic and one moving off the west coast of Africa. Both may develop into tropical depressions within the next week with the names of Gaston and Hermine.
Computer guidance indicates the storms may threaten the eastern Caribbean by the middle of next week.
Sea surface temperatures to the west are very warm and atmospheric conditions will be more conducive for tropical development toward Monday. As of Saturday, both systems have to battle dry air that originated over the Saharan Desert in Africa.
It’s still far too early to get into the exact details as there are many factors that go into play. These include upper air currents, quantity of dry air aloft, strength of the cyclone, amongst other factors. Stronger storms will take more of a northwesterly track.
The bottom line is those that have interests in the eastern Caribbean, including the Lesser Antilles, should monitor the latest forecast should there be further tropical development.
