The Dominica Meteorological Service has released its sub-seasonal forecast update for September 14, 2026, offering residents and key sectors a forward look at expected weather conditions during the most active stretch of the Atlantic hurricane season. The update forms part of the Service's regular climate outlook programme, which is designed to help the country prepare for rainfall, dry spells and other weather hazards in the weeks ahead.
Sub-seasonal forecasts cover a window of roughly two to six weeks, bridging the gap between short-term daily weather forecasts and longer-range seasonal outlooks. For Dominica, that timeframe is especially important during September and October, when tropical systems, heavy showers and flash flooding are most likely to affect the island. The Service publishes these updates to support planning across agriculture, water management, disaster preparedness and everyday household decisions.
The Office of Disaster Management (ODM) continues to urge residents to treat all official weather information as a public-service duty and to monitor bulletins from the Dominica Meteorological Service closely. Vigilance colours — green, yellow, orange and red — are used to signal the level of threat, and residents should be familiar with what each colour means for their community. Green indicates that no immediate threat is expected, while yellow, orange and red signal increasing levels of danger and the need for specific protective action.
Even when a sub-seasonal outlook suggests near-normal or below-normal activity, the Service advises that individual weather systems can still bring intense rainfall over short periods. Dominica's steep terrain and numerous rivers and ravines make the island vulnerable to flash flooding and landslides whenever heavy rain falls, particularly in communities along the west coast and in the interior valleys. Residents in flood-prone areas should keep drains clear, secure loose items around the home and be ready to move to higher ground if conditions worsen.
The 2026 Atlantic hurricane season officially runs from June 1 to November 30, with the statistical peak of activity falling between mid-August and mid-October. Dominica's experience with Tropical Storm Erika in 2015 and Hurricane Maria in 2017 remains a reminder of how quickly conditions can deteriorate. The Meteorological Service therefore encourages the public to use sub-seasonal updates as one part of a wider preparedness routine that includes checking emergency supplies, confirming evacuation routes and staying in contact with official channels.
Farmers, fishers and tourism operators are among the groups that rely on these outlooks to plan their work. The Service notes that sub-seasonal forecasts carry some uncertainty, and users should combine them with daily forecasts, advisories and warnings as an event approaches. Updates are issued regularly through the season, and the public is advised to check for the latest bulletin rather than relying on older information.
Residents can follow the Dominica Meteorological Service and the Office of Disaster Management for the most current guidance. Official warnings should be treated as a public-service duty, and any instruction to shelter, evacuate or remain in place should be followed without delay. The Service reminds the public that vigilance colours are not decorative — they are a direct signal of what action may be required.
The next sub-seasonal update is expected to be published in the coming weeks as the season progresses. Dominicans at home and across the diaspora are encouraged to stay informed and to share verified official information with family and friends, particularly those in vulnerable areas.
