Tropical storm Dolly hurricane concerns are easing as the National Hurricane Center continues monitoring two disturbances across the tropical Atlantic and Gulf of Mexico. In its latest update issued Sunday, Aug. 30, 2026, the NHC said redevelopment of the remnants of Tropical Storm Dolly is unlikely, while another system known as Invest 97-L has a significantly higher chance of strengthening.
Critical Update on the Tropical Storm Dolly Hurricane Threat
The remnants of what was previously Tropical Storm Dolly were located east of Puerto Rico, where showers and thunderstorms continued. However, forecasters reported that the system lacked a closed circulation, a key feature needed for organized tropical development.
Because of that lack of structure, the NHC gave the remnants a 0% chance of formation during the next 48 hours. The chance of development over the next seven days was listed at just 20%.
The system was moving westward to west-northwest at approximately 24 mph. With that forward motion and limited organization, forecasters said redevelopment is not expected as the wave moves across the region.
Heavy Rain and Gusty Winds Still Possible
Although Dolly’s remnants are unlikely to become a new tropical cyclone, the system can still produce unsettled weather. The wave could bring locally heavy rainfall and gusty winds to portions of the Leeward Islands, the Virgin Islands and Puerto Rico during the next several days.
Residents and visitors in those areas should continue to watch local weather alerts, particularly where heavy rain could lead to brief flooding, reduced visibility or difficult travel conditions. The lack of tropical development does not eliminate the possibility of disruptive weather.
Invest 97-L Shows Explosive Development Potential
While Dolly’s remnants are weakening as a tropical threat, Invest 97-L is drawing increased attention from forecasters. The weak low-pressure area was located about 125 miles south of southeastern Louisiana and was producing showers and thunderstorms.
The disturbance is expected to drift westward across the northern Gulf of Mexico. According to the NHC, conditions could allow it to become a tropical depression or possibly a tropical storm in the coming days.
- Formation chance through 48 hours: 70%
- Formation chance through seven days: 70%
- Current location: About 125 miles south of southeastern Louisiana
- Current weather: Showers and thunderstorms around a weak low-pressure area
- Expected movement: Westward across the northern Gulf
The system’s location in the Gulf means weather conditions along parts of the northern Gulf Coast could change quickly. Even before any formal classification, rain, thunderstorms, gusty winds and locally rough seas may affect coastal communities and marine interests.
Why Gulf Residents Should Pay Attention
Invest 97-L has not been designated a tropical depression or tropical storm, and its eventual strength and track remain uncertain. Still, the NHC’s 70% formation probability makes it a system worth watching closely.
Small changes in the low’s organization, steering currents and surrounding atmospheric conditions could influence where the heaviest rain develops. Gulf Coast residents should review their emergency plans, check supplies and remain informed through official forecasts.
For Central Florida, the latest update does not indicate a direct threat from Dolly’s remnants. However, the broader tropical pattern remains active, and conditions in the Gulf can evolve rapidly during hurricane season. Weather impacts may include increased moisture, periods of heavy rain or gusty thunderstorms depending on the system’s eventual track.
What Happens Next?
The National Hurricane Center will continue tracking both disturbances. Dolly’s remnants are expected to remain poorly organized, while Invest 97-L may become more structured as it moves across the Gulf.
Forecasters will focus on whether Invest 97-L develops a closed circulation and whether its thunderstorms become more concentrated. Those changes would help determine whether the system receives an official tropical depression or tropical storm designation.
People in potentially affected areas should avoid relying on outdated forecasts or unofficial social media posts. The most important details, including watches, warnings and projected movement, can change as new information becomes available.
Frequently Asked Questions
Is Tropical Storm Dolly expected to redevelop?
No. The NHC said redevelopment is unlikely because Dolly’s remnants do not have a closed circulation. The system had a 0% formation chance over the next 48 hours and a 20% chance over seven days.
What is Invest 97-L?
Invest 97-L is a weak low-pressure area south of southeastern Louisiana that is producing showers and thunderstorms. It has a 70% chance of becoming a tropical depression or tropical storm within seven days.
Could Dolly’s remnants still bring dangerous weather?
Yes. Even without tropical development, the remnants may produce locally heavy rain and gusty winds across portions of the Leeward Islands, the Virgin Islands and Puerto Rico.
Should Central Florida residents be concerned?
There is no direct threat to Central Florida indicated in the update. However, residents should continue monitoring official forecasts because Gulf systems can change quickly during hurricane season.
