Sargassum forecasts: finally the return of the low grounding level


In its pelagic sargassum stranding monitoring and forecasting bulletin for the northern islands communicated this Monday, October 3, 2022, Météo France finally lowers the risk of seaweed stranding for Saint-Martin and Saint-Barthélemy to low for both territories.

Despite the lack of recent usable images caused by the very numerous clouds which make Sargassum detection and analysis difficult, Météo France refers to the latest reports which indicate that the rafts seem quite scattered near Saint-Martin and Saint-Martin. Bartholomew. 

Arrivals, if any, should be fairly punctual. Indeed, on the satellite images from September 24 to 28, 2022, the detections of sargassum were still quite numerous, more or less long filaments transited west to north-west, between St-Kitts and Barbuda, which could partially be the source of groundings on the southern coast of the Northern Islands during the period. Since then, little or no grounding has been observed. As far as trends for the next two weeks are concerned, Sargassum arrivals will be more punctual in the Northern Islands. The many sargassum present in the east of the West Indies, especially off Martinique and Dominica, threaten especially Dominica and Guadeloupe, and to a much lesser extent the Northern Islands. The detections become relatively numerous again around Barbados but the currents are not very conducive to sargassum coming up from the south/south-east, which still leaves some respite to the territory of Saint-Martin and the possibility of finalizing the cleaning of the beaches affected by groundings, with priority on Cul-de-Sac, Mont Vernon and Orient Bay. _Vx
