Over the years, forecasters at the Chaudron station have implemented weather surveillance and cyclone alerts to warn the population of risks linked to these climatic events. The different colors indicate the importance of the potential threat for a geographic area or the entire island.
Four colors are used for warnings regarding wind, heavy rain and swell.
When the card is green, no particular vigilance is brought to your attention.
Yellow vigilance asks you to be attentive. A series of swells, gusts of wind, heavy rain and possibly thunderstorms could affect an area of the department.
Orange vigilance asks you to stay informed. Potential dangers (waves, rain, storms or winds) are anticipated. They will affect the municipalities tinted orange.
Red vigilance leaves no room for doubt. The risk is very high. The expected phenomena represented by their intensity are considered dangerous.
Take the time to read the instructions in the tab: find out more on the Météo-France La Réunion website.
The pre-alert: yellow has been abandoned.
It is triggered by Météo-France services. A cyclone threat could affect the island within 24 to 72 hours. It allows you to do essential shopping in the event of confinement.
Orange alert
The threat is circulating near the island and could impact the department in the next 24 hours. It's time to bring in animals, objects that could be blown away by gusts of wind, protect doors and windows…
Red Alert
The arrival of the meteor is imminent (3 hours maximum). You must remain confined and keep informed of the evolution of the cyclone. It is forbidden to go out and it is recommended to call if absolutely necessary.
Purple Alert
I CONFINE MYSELF: exceptional danger.
“A tropical cyclone (major cyclone) impacts Reunion Island with cyclonic winds of more than 200 km/h and represents an imminent danger for all or part of the territory.”
This phase involves a return to red alert, then a backup phase to allow the various services to carry out the necessary reconnaissance (road network in particular) before ending the confinement.
Attention ! These precautions may seem excessive, when the phenomenon does not impact the town or the island as feared by forecasters. However, they aim to protect the population. It is essential to follow the various instructions to avoid a tragedy!
