Martinique remains on orange vigilance for heavy rains and thunderstorms today (Wednesday, July 29, 2020) and on yellow vigilance for dangerous seas on the coast and strong winds.

The weather conditions are still bad in Martinique today (Wednesday July 29, 2020) with transient intense and sometimes stormy rains, often associated with strong gusts of wind.

The cyclonic system continues its route west northwest but bands of rain and sometimes thunderstorms linked to this system will affect the island during the day.

The expected accumulations are of the order of 50 to 70 mm, which will be added to the already significant accumulations of last night (60 to 70 mm, locally 80 to 95 mm).

The rains will weaken markedly the following night. Over the entire episode, the amounts of rain could therefore reach 120 to 160 mm (1 mm = 1 liter of water per square meter).

The wind is currently variable weak, it will move to the South South-East at the beginning of the morning and strengthen. It could again blow in strong gusts in the downpours, then reaching 60 to 70 km / h locally 80 to 90 km / h.

The Atlantic coast and the relief are the areas most exposed to these very strong gusts. Mitigation is expected overnight from Wednesday to Thursday.

Under the influence of the strong wind, the sea condition deteriorated. The hollows will exceed 3m00 in the Atlantic and canals, and on the shores of the Caribbean coast, the sea will be unusually rough with waves between 0.5 m and 1 m.
