Tropical Update: Tracking Invest 99-L in the eastern Atlantic

Tropical Update: Tracking Invest 99-L in the eastern Atlantic

The Gulf of Mexico, Caribbean and western Atlantic Ocean remain void of any tropical activity late this week as Tropical Storm Emily's remnants move quickly northeastward and away from the United States.

Much further eastward, a strong tropical wave is emerging off the western African. This wave has been classified Invest 99-L and is producing quite a bit of shower and thunderstorm activity associated with it. The National Hurricane Center has given it a 30-percent-chance of developing into a Tropical Depression, or stronger, within the next 48 hours, and a 60-percent-chance within the next five days.

Regardless of development, it should continue on a west or west-northwest track for the next several days. Interests in the eastern Caribbean need to keep an eye on this system through early next week. Exact track and strength remain highly uncertain.

Forecast data is also suggesting that something may develop over the southern Gulf of Mexico or western Caribbean early next week, likely tracking deeper into the Gulf of Mexico regardless of development.

As tropical activity continues to increase, now is the time to review your hurricane plans and make sure any alterations from 2016 have been made.

Check in with the First Alert Forecast Team on television, in the WTOC Weather App and at the Hurricane Center at, periodically for tropical updates.
