A gradual intensification of the disturbance possibly at the stage of depression or even tropical storm, passing in the night from Tuesday to Wednesday over the extreme south of the Antilles Arc, with a center probably between Trinidad and St-Vincent / Grenadines, Martinique weather forecast . (Re) see the explanations of specialist Jean-Noël Degrace.
Tropical wave N°10, which gave rains and thunderstorms over the last 24 hours in Martinique (20-50mm in 12 hours, 30-80mm in 24 hours very locally up to 100mm) is moving away in the Caribbean Sea and gives way to drier weather and some nice sunny spells this afternoon.
Tropical wave No. 11, less than 1400 km from the Caribbean Arc, very south (south of 10 North) about 3000 km (around 30W) is evolving in an environment that will be favorable to its development and the scenario envisaged since Friday seems to be confirmed… namely a progressive intensification of the disturbance possibly at the stage of depression or even tropical storm, passing in the night from Tuesday to Wednesday over the extreme south of the Antilles Arc, with a center probably between Trinidad and St -Vincent/Grenadines.
2 cyclone hunter planes (US Air Force / NOAA) could be in the area this afternoon to better investigate the phenomenon and possibly initiate trajectory and intensity forecasts if necessary.
Martinique should therefore remain outside the strongest conditions. Nevertheless, we can expect, from the night of Tuesday to Wednesday, heavy rains accompanied by a few gusts of up to 80-100 km, indicates Martinique weather.
The sea state should also deteriorate with waves reaching or even exceeding 3.5m on average in the Atlantic and especially in the St. Lucia Channel.
