The Atlantic hurricane season runs from June 1 to November 30 each year, with peak activity from August to October.
Debby’s impacts will extend into the Northeast by the end of the week
After stalling for days over the Southeast, Debby is now poised to move north, bringing significant flooding threats from the Mid-Atlantic to New England.
Goodbye, Debby. Now it’s time to look for a tropical wave.
Six days after the storm first made landfall as a hurricane in Florida and then a second time as a tropical storm in South Carolina, the National Hurricane Center issued its final warning for Debby on August 9. The storm brought historic rainfall from Florida to the Carolinas.

Elsewhere in the tropics, a new tropical wave in the Atlantic is likely to develop into a tropical depression early next week as it approaches the Lesser Antilles and the Caribbean Sea.
If the storm gets a name, it will be Ernesto.
Tropical Storm Debby made its second landfall near Bulls Bay, South Carolina, just before 2 a.m. on Thursday, August 8. Sustained winds were 50 mph.
Debby first made landfall as a hurricane in Steinhatchee, Florida, around 7 a.m. on Monday, August 5. Sustained winds were 80 mph.
Here is the latest update from the National Hurricane Center in Miami as of August 10, 8:00 a.m.:
Near the Lesser and Greater Antilles (AL98): Rain and thunderstorm activity has increased since August 9 in association with a tropical wave located about halfway between Cape Verde and the Lesser Antilles. Gradual development of this system is possible over the next few days as it moves westward to west-northwestward across the central tropical Atlantic.
After that, conditions are expected to become more conducive to development, and a tropical depression is likely to form early to mid next week as the system approaches and then moves near or over the Lesser Antilles. The system is expected to continue to move primarily west-northwestward and could reach parts of the Greater Antilles mid to late next week.
- The probability of occurrence within 48 hours is low at 30 percent.
- The probability of occurrence within 7 days is high at 80 percent.
Colorado State University predicts an 85 percent chance of hurricane activity through August 19
CSU meteorologists estimate that the probability of hurricane activity between August 6 and 19 is 85%.
“The main risk area for severe hurricanes is in the tropical Atlantic east of the Lesser Antilles in early to mid-August.”
The next two-week forecast for the period August 20 to September 2 will be released on August 20.
On August 6, CSU updated its seasonal forecast for the 2024 Atlantic hurricane season, reducing the predicted number of named storms from 25 to 23, but maintaining its forecast of 12 hurricanes and six major hurricanes.
What do the colored areas on the NOAA map mean?
The hatched areas on a tropical map indicate “areas where a tropical cyclone – that is, a tropical depression, a tropical storm or a hurricane – could develop,” said Jamie Rhome, deputy director of the National Hurricane Center.
The colors indicate how likely the development of a system could be: yellow stands for a low probability, orange for a medium probability and red for a high probability.
The National Hurricane Center generally does not issue tropical warnings until there is a named storm, but there is one exception.
“If a system is close to land and there is potential for development, the National Hurricane Center will not wait to issue warnings, even if the system has not yet developed into a full-blown storm. This gives residents time to prepare,” Rhome said.
Who is likely to be affected?
It is currently too early to judge whether the tropical wave in the Atlantic will have an impact on Florida or the USA.
Meteorologists urge all residents to continue to monitor the tropics and stay prepared. This advice is especially important during what is expected to be a very active hurricane season.
NOAA updates forecast for 2024 hurricane season
NOAA has updated its forecast for the 2024 Atlantic hurricane season, more than two months and four named storms after releasing its first forecast in May.

Here is the latest forecast:
- Named storms: 17-24
- Hurricanes: 8-13
- Major hurricanes: 4-7
- Above normal season: 90%
