US Joins Bahamas and Mexico in Focus as Tropical Activity Builds Despite El Niño Suppressing Atlantic Storms, as NOAA tracks conditions across two ocean basins. US Joins Bahamas and Mexico in Focus as Tropical Activity Builds Despite El Niño Suppressing Atlantic Storms because a central Atlantic disturbance has a 30% seven-day formation chance, while longer-range signals point to possible development near the Bahamas and southern Mexico. El Niño is still limiting Atlantic hurricane activity through strong wind shear. However, September remains a key storm month, so travellers should follow official forecasts closely as conditions can change quickly across coastal destinations.
Official Tropical Weather Data at a Glance
| Weather indicator | Latest official NOAA information |
|---|---|
| Central subtropical Atlantic disturbance | More than 1,000 miles east-southeast of Bermuda |
| 48-hour formation chance | Near 0% |
| Seven-day formation chance | 30% |
| Atlantic movement | West-northwestward |
| Bahamas outlook | Tropical or subtropical development may become possible near or north of the islands |
| Southern Mexico outlook | Development may become more favourable nearby during Week 3 |
| Atlantic season outlook | 75% chance of below-normal activity |
| Named storms forecast | 7–13 |
| Hurricanes forecast | 2–6 |
| Major hurricanes forecast | 0–2 |
| Atlantic ACE forecast | 30%–90% of median |
| ENSO status | El Niño Advisory |
| Very strong El Niño probability | Greater than 90% during Northern Hemisphere autumn and winter |
NOAA stresses that seasonal and longer-range outlooks do not predict a specific hurricane landfall. Daily weather patterns determine where an individual tropical cyclone eventually travels.
Central Subtropical Atlantic Becomes the Immediate Area to Watch
The National Hurricane Center is monitoring a trough of low pressure located more than 1,000 miles east-southeast of Bermuda.
The system is producing disorganised showers and thunderstorms. Strong upper-level winds are currently making conditions unfavourable for development.

However, as the disturbance moves west-northwestward across the central subtropical Atlantic, conditions are forecast to become more favourable for gradual organisation during the middle to latter part of the week.
The NHC places its formation chance at near zero during the next 48 hours and 30% during the next seven days.
There is no confirmed land impact at present, and the system has not become a tropical depression or named storm.

Bahamas Enters NOAA’s Longer-Range Atlantic Outlook
The Bahamas appears in a different type of official forecast.
NOAA’s Climate Prediction Center says unsettled weather across the western Atlantic near or north of the Bahamas could provide an opportunity for tropical or subtropical development.
This outlook covers 16–29 September 2026 and is designed to highlight broader areas where tropical cyclone development could become more favourable.
It does not mean a named storm has formed near the Bahamas. It also does not confirm that the islands will experience a tropical storm or hurricane.
NOAA says the Atlantic as a whole remains broadly unfavourable because of strong Pacific-related upper-level divergence and wind shear associated with El Niño.
Mexico Enters Focus as Eastern Pacific Remains More Active
Mexico provides the second major geographic travel angle.
NOAA says the Madden-Julian Oscillation could increase conditions favourable for tropical cyclone development closer to Mexico’s southern coast during Week 3.
The signal is in the eastern Pacific, not the Atlantic.
NOAA expects the Pacific to remain much more favourable for tropical cyclogenesis under the strong El Niño pattern. Its longer-range outlook indicates continued potential for eastern Pacific activity while the Atlantic remains comparatively suppressed.
Again, this is not a forecast of a storm striking Mexico. It identifies an environment where tropical cyclone formation may become more favourable.
El Niño Continues to Hold Back Atlantic Hurricanes
The biggest reason for the quiet Atlantic remains El Niño.
NOAA issued an El Niño Advisory on 10 September 2026 and said El Niño is strengthening. The Niño-3.4 sea-surface temperature anomaly reached +1.8°C, while the Niño-3 region reached +2.5°C and Niño-1+2 reached +3.4°C.
NOAA now gives a greater than 90% chance of a very strong El Niño during the Northern Hemisphere autumn and winter of 2026–27.
El Niño generally increases vertical wind shear over the tropical Atlantic. Strong shear makes it harder for tropical systems to organise and maintain deep thunderstorms around their centres.
That influence led NOAA to reduce its Atlantic seasonal outlook in August.
NOAA Forecasts a Below-Normal 2026 Atlantic Season
NOAA now gives the Atlantic a 75% probability of a below-normal hurricane season, compared with only 20% for near-normal activity and 5% for an above-normal season.
The official forecast calls for:
- 7–13 named storms
- 2–6 hurricanes
- 0–2 major hurricanes
- ACE at 30%–90% of the long-term median
The 1991–2020 averages are approximately 14 named storms, seven hurricanes and three major hurricanes. NOAA also notes that August, September and October normally form the core of Atlantic hurricane activity.
A quieter season, however, does not remove the risk of a damaging storm.
US, Bahamas and Mexico Travellers Should Follow Official Forecasts
For travellers across the United States, Bahamas and Mexico, the current signals call for awareness rather than alarm.
No major land impact has been confirmed from the central Atlantic disturbance. The Bahamas signal remains a longer-range possibility, while the southern Mexico signal relates to potential eastern Pacific development later in the forecast period.
Travellers planning flights, cruises, resort stays or coastal road trips should check the National Hurricane Center and local government weather and emergency information before departure.
NOAA specifically warns that seasonal hurricane forecasts cannot predict where storms will make landfall. Even a below-normal season can produce a serious hurricane. With September still inside the peak period of the hurricane season, changing conditions across the Atlantic, Bahamas and eastern Pacific will require continued monitoring.
US Joins Bahamas and Mexico in Focus as Tropical Activity Builds Despite El Niño Suppressing Atlantic Storms because official NOAA outlooks show different levels of tropical potential across the Atlantic and eastern Pacific. The central Atlantic disturbance remains the most immediate system to watch, while the Bahamas and southern Mexico appear in longer-range development signals. El Niño continues to reduce wider Atlantic storm formation by increasing wind shear, but it cannot remove all risk. Travellers should therefore stay alert, check official updates and avoid assuming a quieter hurricane season means coastal destinations are completely safe from sudden tropical development today.
