Meteorological evolution of tropical storm Melissa toward a major hurricane
Since its formation in the warm waters of the Caribbean Sea, Melissa has quickly gained intensity, confirming the predictable trend of active storms during the 2025 cyclone season. The U.S. National Hurricane Center announced that Melissa is nearly stationary but is expected to soon move northeast then north while intensifying. This predicted movement poses a significant risk for island territories close to its path.
Oceanic and atmospheric conditions, including above-average sea surface temperatures, strongly favor this strengthening. Forecasts indicate:
- A passage to hurricane status by Saturday, with sustained winds rapidly exceeding 120 km/h ⚡
- An intensification into a “major hurricane” (category 3 or higher) by Sunday 🌪️
- Partial stagnation that will prolong episodes of heavy precipitation 🌧️
These combined elements significantly increase the risk of extreme events such as torrential rains and violent winds. The NHC even assesses the possibility that Melissa could reach category 4 or 5, which would make it the most devastating storm of the season and a system to follow very closely for the Caribbean area. The table below summarizes the key forecasts for the storm’s trajectory and strength:
| Day 🌞 | Estimated position 📍 | Forecast category 🌟 | Winds 🍃 (km/h) | Major risks ⚠️ |
|---|---|---|---|---|
| Friday | 260 km S-SE of Kingston | Tropical storm | 90 | Heavy rain, local flooding |
| Saturday | Off the south-west coast of Haiti | Category 1-2 hurricane | 120-155 | Violent winds, heavy rain, landslides |
| Sunday | Near Haiti/Jamaica | Major hurricane (3+) | 178+ | Risk of catastrophic flooding, major landslides |
Specialized organizations, notably Météo France and La Chaîne Météo, maintain constant monitoring of this storm, offering daily bulletins and real-time updates to enable populations to follow the evolution live.
