Tropical Storm Humberto Forecast Update: NOAA Hurricane Tracker, Spaghetti Models, and NHC Alerts Point to a Potential Major Hurricane in the 2025 Season
The 2025 Atlantic hurricane season is already proving to be one of the most active in recent memory, and all eyes are now on Tropical Storm Humberto. According to the latest updates from the National Hurricane Center (NHC) and NOAA Hurricane Tracker, Humberto continues to strengthen in the Atlantic with forecasts showing it could soon become a hurricane, possibly intensifying into a major storm.
Current Status from the NHC and NOAA Hurricane Tracker
The NHC’s Public Advisory No. 5 places Humberto at latitude 21.9° N and longitude 57.0° W, moving northwest at 6 mph. While no watches or warnings are in place for coastal areas, meteorologists are closely monitoring the storm’s slow progress.
Key points from the NHC advisory:
-
Maximum sustained winds: gradually increasing with potential to reach hurricane strength within 48 hours.
-
Expected motion: slow west-northwest to northwest before curving northward.
-
Forecast cone: emphasizes uncertainty beyond 3–5 days, not indicating the full range of impacts.
Forecast Intensity and Strengthening Outlook
Meteorological models suggest that Humberto could reach hurricane status by Friday and possibly strengthen into a Category 3 hurricane by early next week.
A comparison of expected storm categories:
| Forecast Period | Intensity Estimate | Category |
|---|---|---|
| Next 24 hours | 65–70 mph winds | Tropical Storm |
| 48–72 hours | 75–95 mph winds | Category 1–2 Hurricane |
| 4–5 days | 110+ mph winds | Major Hurricane (Category 3) |
While current forecasts keep Humberto over open waters, nearby regions such as Bermuda could experience rough seas and stronger winds from outer rainbands.
Spaghetti Models Show Wide Track Uncertainty
The spaghetti models for Tropical Storm Humberto highlight a wide spread of possible paths. Some models show the storm recurving into the central Atlantic, while others suggest a temporary westward drift before turning north.
One of the most intriguing factors is the potential interaction with Invest 94L, which may soon strengthen into Tropical Storm Imelda. If both storms form near each other, the Fujiwhara effect could occur, causing the two systems to rotate around a common center and alter their predicted tracks.
This possibility adds significant uncertainty to the forecast, and the NHC stresses that even small shifts in the steering pattern could bring Humberto’s impacts closer to the U.S. East Coast.
Impact Scenarios for the U.S. and Coastal Areas
At present, Humberto is not forecast to make landfall in the United States, but coastal impacts remain possible. The storm’s size and oceanic swells could generate dangerous surf and rip currents along parts of the Southeast coastline.
Meanwhile, Invest 94L / Tropical Storm Imelda could present a more immediate risk. Forecasts indicate that it may track toward the Carolinas, Georgia, and the Bahamas, increasing the chances of heavy rainfall and coastal flooding in early October.
Meteorologists in Virginia and the mid-Atlantic have already flagged the potential for hazardous conditions if Imelda strengthens and edges closer to the coastline.
The Role of the Fujiwhara Effect
The Fujiwhara effect becomes a concern when two tropical systems form close enough to influence each other’s paths. If Humberto and Imelda align within a few hundred miles, scenarios include:
-
One storm absorbing the other.
-
Both storms rotating around each other before separating.
-
Altered tracks that could shift one storm closer to land unexpectedly.
The Houston Chronicle and other meteorological outlets warn that this rare phenomenon could make forecasting much more difficult in the days ahead.
What to Watch in the Next 72 Hours
-
Humberto’s rapid intensification as it strengthens into a hurricane.
-
Development of Invest 94L into Tropical Storm Imelda, which could become the main U.S. threat.
-
Shifts in spaghetti models that show whether Humberto will remain over the Atlantic or drift closer to land.
-
Coastal conditions such as strong rip currents and elevated wave activity along the Southeastern seaboard.
The 2025 Atlantic hurricane season, which NOAA has already projected as above-average, continues to validate those predictions. With Tropical Storm Humberto, Tropical Storm Imelda, and other potential disturbances, the coming weeks could test coastal preparedness and forecasting accuracy like never before.
