One of two tropical features that AccuWeather meteorologists have been monitoring for prior to mid-October will threaten to bring torrential rain and gusty winds to many of the islands in the northern Caribbean from late this week to next week.
Because of the likelihood of the area of showers and thunderstorms continuing to organize and strengthen, AccuWeather meteorologists have dubbed it a tropical rainstorm to raise public awareness and plan ahead.
“Initially, the rainstorm will glide along on a trajectory that takes the core just to the north of the Leeward Islands,” AccuWeather Lead Hurricane Expert Alex DaSilva said, “But over time, a more southward drift is most likely with some wiggle room ranging from a more west-northwest to a southwest track.”
The longer the system stays north of the islands, the higher the chance for it to strengthen.
“It is possible the rainstorm goes on to become a hurricane, let alone the next depression and named storm of the 2024 Atlantic season,” DaSilva said.
The next name on the list of tropical storms for 2024 is Nadine.
The long-term possibilities of this tropical rainstorm include a path more to the northwest into the southern Bahamas, but it is more likely to take a southwesterly track over the larger islands of Hispaniola and Cuba.

“From later this weekend to early next week, either the feature will encounter increasingly hostile breezes (wind sheer) to the north or the mountainous terrain of the Greater Antilles to the south,” DaSilva said, “Either would likely lead to a loss of wind intensity and could even totally break up the system.”
The atmosphere would have to change dramatically for the storm to approach Florida. Stiff east-northeast breezes creating the strong wind shear would have to subside, and a storm high in the atmosphere over the Bahamas would have to dissolve or move away.
The winds will create local problems for Florida in the form of rough surf, beach erosion and coastal flooding on the Atlantic side of the peninsula.
People should not just focus on where the center of the storm will track.
As the rainstorm grows in size and potentially evolves into a depression, tropical storm and possibly a hurricane, bands of rain and gusty winds will expand outward from the center.
Even a strengthening tropical storm passing to the north of the Leeward Islands, as well as the United States and British Virgin Islands and Puerto Rico is likely to create locally torrential downpours and damaging wind gusts in squalls. Surf and offshore seas will build in the vicinity of the storm.
Farther west, any direct or indirect encounter with the mountainous terrain from Puerto Rico to Hispaniola and Cuba can lead to life-threatening and damaging flash flooding and mudslides.
Should the storm take a more southern route, survive the trip across Hispaniola and/or Cuba, and reach the northern Caribbean directly, there is a chance it will regain intensity over the very warm waters in the region. However, that would not be until later next week.
The rainstorm approaching the northern Caribbean could have some competition from gathering the name Nadine. A growing area of showers and thunderstorms in the western Caribbean has a chance at evolving into a tropical depression or storm before pushing into Central America later this week. Following Nadine, Oscar is the next name on the list for 2024.
