MARIGOT: In its monitoring and forecasting bulletin of pelagic sargassum stranding for the Northern Islands released this Monday, October 3, 2022, Meteo France finally lowers the risk of stranding of algae for St. Martin and St. Barts to low for both territories.
Despite the lack of recent usable images caused by the many clouds that make it difficult to detect and analyze sargassum, Meteo France refers to the latest reports that indicate that the rafts seem to be quite scattered near Saint-Martin and Saint-Barthélemy. The arrivals, if any, should be quite punctual. Indeed, on satellite images from September 24 to 28, 2022, Sargassum detections were still quite numerous, with more or less long filaments transiting west to northwest, between St. Kitts and Barbuda, which could partially be the source of strandings on the southern coast of the Northern Islands during this period.
Since then, few or no strandings have been observed. In terms of trends for the next two weeks, Sargassum arrivals will be more spotty in the Northern Islands. The numerous sargassum present in the eastern Caribbean, especially off Martinique and Dominica, threaten mainly Dominica and Guadeloupe, and to a much lesser extent the Northern Islands. The detections are again relatively numerous around Barbados, but the currents are not very favorable to upwelling of sargassum from the south/southeast, which still leaves some respite for the territory of Saint-Martin and the possibility of finalizing the cleaning of the beaches affected by the strandings, with priority given to Cul-de-Sac, Mont Vernon and the Orient Bay.
