Since this Thursday afternoon (February 8), Martinique has been under a yellow alert for heavy rain and thunderstorms and violent winds. The orange alert for waves-submersion, declared at the end of the morning, is still in force.
According to Météo France, “a rain-storm front focused on Guadeloupe is shifting towards the East and will affect Martinique next night with a strengthening of the wind linked to its passage”.
The south to southeast wind is already causing degraded sea conditions on the Caribbean coast.
A depression located north of Hispaniola is generating a northwest swell, which will impact the Caribbean coasts from this evening.
Locally heavy and stormy precipitation is expected next night and could result in accumulations of 50 to 80 mm. An improvement is expected tomorrow around midday.
A shift in the wind to the northwest and strengthening is expected in the evening. Values will reach 35 to 45 km/h inland with gusts of 70 to 80 km/h particularly on the coast and exposed areas. The improvement will occur in the morning of Friday.
Under the effect of the south to southeast wind, the average troughs are currently between 0m50 and 0m80 on the south coast and the Caribbean coast. At the end of the afternoon, they can cause flooding in low-lying areas of the coast (from Prêcheur to Sainte-Anne) and require boats to anchor.
Sea conditions will deteriorate from the evening onwards. On the one hand, the direction of the waves will become more impactful, on the other hand, under the effect of a strengthening of the wind, the average troughs will reach 1m50 to 1m80 at the coast. This unusual unrest could cause greater flooding in low-lying areas of the coast. The peak of the event is planned for this night from Thursday to Friday. A gradual attenuation will take place on Friday.
- average depths from 0m60 to 0m70
- maximum waves from 1m00 to 1m20 – South-West direction swell on periods of 5 seconds.
