All tropical storm watches related have been discontinued in Florida, as confidence increases that Tropical Storm Humberto will stay well offshore of the Atlantic Coast this weekend.
The season’s eighth named tropical storm was classified by the National Hurricane Center late Friday night. Hurricane hunters found winds up to 40 mph and an area of strong thunderstorm activity on the storm’s northeast side, the center said. At the time, strong upper-level winds from the southwest were limiting the tropical storm’s ability to become better organized. However, those winds are expected to lighten up Saturday when forecasters say Tropical Storm Humberto will be poised for intensification.
Tropical Storm Humberto did not have a well-defined center of circulation until Friday afternoon. There is a much larger margin of error in a track forecast of a developing system without a center. This was quite evident when comparing model data over the past three days with the former Potential Tropical Cyclone Nine.
Now that confidence has increased that Tropical Storm Humberto will not directly affect the United States, our attention turns to the rest of the tropical Atlantic. As of Saturday morning, the National Hurricane Center was monitoring three tropical waves with some probability of developing. The official 5-day tropical outlook is embedded below.
None of the disturbances being tracked are an immediate threat to the State of Florida, although long range forecast data suggests one or two of them in the central Atlantic will have an opportunity to become a formidable tropical storm or hurricane in the next week or two. Even though the climatological peak of hurricane season has passed, historical records show Florida hurricane landfalls are more frequent over the next four weeks compared to the prior four.
