And Then There Were Two…With One Posing Threat To Caribbean

weatherFLORIDA, United States, Monday August 22, 2016 – Two tropical disturbances in the Atlantic Ocean may become tropical depressions or storms, with one of them threatening to drench the Caribbean with heavy rain whether or not it develops further.

Invest 99-L and Invest 90-L are behind what used to be Tropical Storm Fiona. It’s Invest 99-L, a tropical wave located about 900 miles east of the Lesser Antilles, that poses the greater threat to the Caribbean.

The National Hurricane Centre (NHC) says that system has a 50 per cent chance of development into a tropical depression or tropical storm over the next five days. It should continue in a general west or west-northwest trajectory the next several days and reach the Lesser Antilles by late tomorrow or early Wednesday, and then spread through the northeast Caribbean Islands into Thursday.

Regardless of whether it is Invest 99-L, a tropical depression or tropical storm, the system could bring heavy rain to the Lesser Antilles beginning late tomorrow, according to forecasters with the Weather Channel. It could possibly threaten the Bahamas later on, but it’s too early to say for sure.


Farther east, Invest 90-L, an area of low pressure associated with a tropical wave, is moving away from Africa and has better prospects for development in the near-term future.

It is likely to develop into a tropical storm, perhaps as early as today. The NHC says it is almost positive it will form within the next 48 hours.

The long-range path for Invest 90-L takes it on a northwest course that has the potential to keep it away from land. Some computer models also ramp up the storm into a powerful hurricane.


Meantime, Fiona is on her way out, having weakened from a tropical storm to a tropical depression late last night.

At 11 a.m., it was 495 miles north northeast of the northern Leeward Islands and about 615 miles south southeast of Bermuda, carrying maximum sustained winds of 35 miles per hour.

The NHC said gradual weakening is forecast during the next 48 hours, during which time Fiona could become a remnant low, bringing a few showers to Bermuda.
