Regarding this mini-tornado, the climatologist Christophe Valère-Montout de Météo France talks about an exceptional event, possibly from a “Navy“However, the archipelago is in an area favorable to the development of this type of phenomenon, after the United States and Australia. 1500 sea tubes are observed locally each year, mainly by fishermen, at sea.
It is the fact that they arrive on the ground, with such power, which is rarer.
The one who concerned Baie-Mahault is estimated at F1 level on the Fujita scale (moderate winds from 116 to 179 km/h). It is even possible that there have been several simultaneously, in the area.
The navy trompe is a column of air mixed with rotation water, forming a cloudy funnel, under a convective cloud above a water area. These micro-scaling phenomena form when the conditions are very unstable, while cold air passes over hot waters. Generally less intense than a tornado, they dissipate once on earth. There are two types: cold air and tornadoes (source: techno-science.net).
A mass of wet and unstable air, carrying a rainy activity locally marked, continues to affect the Guadeloupe archipelago. These punctually stormy showers are not very mobile, given the weakness of the Alizé. At the beginning of the afternoon, strong showers, sometimes stormy, occur on the large marine cul-de-sac, overflowing on the north of Basse-Terre. Others occur under the wind of Marie-Galante, even on the relief of the South Basse-Terre.
Strong intensity and sometimes stormy showers can still be triggered quickly, today and can generate significant combination of rain reaching, or even exceeding, 80mm of rain in 3 hours. Temporary floods are therefore to be feared.
No sector is, a priori, sheltered from the threat.
The most exposed regions remain the Basse-Terre and the municipalities bordering the Grand Cul-de-Sac Marin.
Rainy and stormy activity could continue until evening, even at the start of the night.
Here are the accumulations of rains noted in the pluviometers of Météo France, on the last hour:
- 21.7 mm in Sofaia Sainte-Rose ;
- 11.7 mm in Capesterre-Belle-Eau;
- 7mm in a small town.
