Tropical Depression Nine: Gulf of Mexico at threat for a potential hurricane

This system has meteorologists’ attention because both the American and European weather forecasting models show it developing into a hurricane and entering the Gulf of Mexico early next week.

Nine has sustained winds of 35 mph about 615 miles east-southeast of Jamaica, tracking west-northwest at 13 mph.

“Only slow intensification is forecast over the next day or so, followed by more significant intensification over the weekend and early next week,” the hurricane center said.

In the short term, Nine is forecast to bring heavy rain to Aruba, Bonaire, Curacao, northern Venezuela and northern Colombia which could lead to flash flooding and mudslides across the islands.

The system is then forecast to gain strength, intensifying into a tropical storm as it tracks towards Jamaica and the Cayman islands. Tropical storm watches and warnings are likely to be issued for these locations within the next 24 hours.

Forecast rainfall totals:

  • Aruba, Bonaire, and Curacao: Additional 1 to 2 inches
  • Northern Venezuela: 2 to 5 inches
  • Northern Colombia: 3 to 6 inches
  • Jamaica: 4 to 8 inches with local maximum up to 12 inches
  • Cayman Islands: 4 to 8 inches
  • Southern Haiti and Southern Dominican Republic: 2 to 4 inches with local maximum up to 6 inches

After passing through the Caribbean this weekend, the system is forecast to track near or over western Cuba as a hurricane and enter the Gulf of Mexico early next week.

“The model guidance early on is a fairly good agreement, but a larger across-track spread begins to take shape by 48 hours,” the hurricane center said. “There is still a healthy amount of uncertainty in the track forecast at the day 4-5 time frame.”

Both major weather forecast models, the American and European, currently show the system tracking into the Gulf of Mexico early next week; however, the American shows a more westerly track and the European shows a more easterly track.

Friday morning, the European model showed the storm over the Florida Keys on Tuesday, impacting much of southern Florida. The American model showed the storm impacting much of the west-central coast of Florida on Wednesday.

The official forecast track from the hurricane center splits the difference between the weather forecast models, showing the storm approaching the Florida peninsula late Tuesday night or early Wednesday morning as a strong Category 2 hurricane.

Regardless of where the storm ends up tracking, conditions in the Gulf are favorable for the system to strengthen, and it will do that very rapidly, Maria Torres, hurricane center spokesperson, told CNN.

It has been a slow start to what was forecast to be an above-average hurricane season. Only one storm has made landfall in a US territory, and no hurricane has made landfall or threatened the contiguous United States.

Now, a week past the peak of hurricane season, the tropics seem to have woken up, and forecasters are concerned people have let down their guard.

“After a slow start, the Atlantic hurricane season has ratcheted up quickly,” Phil Klotzbach, research scientist at Colorado State University, tweeted.

“People tend to lower their guard and think, oh, yeah, we’re out of the woods,” Torres said. “But in reality, the season continues. We are still in September; we still have October to go. Anything that forms over either the Atlantic or the Caribbean is something that we need to keep monitoring very closely.”

The Atlantic hurricane season ends November 30.

No matter what, if you live in the Caribbean, Florida and other states along the Gulf Coast, pay attention to the updated forecasts this weekend into early next week.
