Heres my photobucket album of Gamede (so far) I'm adding when I get the chance.

Turns out some of the world records were actually broken by Gamede.

With GAMEDE and 27 years after HYACINTHE, La Reunion beats his own world records of precipitations over the durations from 3 to 9 days.



It is pointed out that GAMEDE, classified intense tropical cyclone during its maximum phase, is remained with less than 400 km of La Reunion during nearly 4 days, with a zone of extremely vast influence in term of winds and precipitations. The winds were certainly strong over a long duration, but were not of very exceptional nature. On the other hand, the rains, although not having known extreme peaks of intensity, were very regular and very abundant in all the tops of the island, producing by accumulation of the even exceptional remarkable water blades over durations of one at several days. Data of recording rain-gauges recovered a posteriori in the days which followed the end of the episode, made it possible to establish that world records of precipitations had been beaten.

After having stripped and having checked the last data of the recorders of its network of measuring sites, Meteo-France thus concerned the exceptional office pluralities between the 24 and on 28 February:



Over 12 midnight: 1625 mm with the Commerson Crater, thus approaching the official world record of 1825 mm measured with Jib-Jib with the passage of “DENISE” in 1966. One raises also 1489 mm with Hell-Borough and 1295 mm with Bélouve.



Over 48 hours: 2463 mm with the Commerson Crater, almost with equality with the world record of 2467 mm Aurère going back to 1958. Other remarkable values: 2358 mm with Hell-Borough and 2185 mm with Bélouve.



Over 72 hours: 3929 mm with the Commerson Crater and 3264 mm with Hell-Borough, thus exceeding the preceding world record (3240 mm) which had been measured with Large-Ilet with the passage of “HYACINTHE” in 1980. One also measures: 2824 mm with Bélouve and 2321 mm with Cilaos.



Over 4 days: 4869 mm with the Commerson Crater and 3633 mm with Hell-Borough. There still, one largely exceeds the preceding world record which was 3551 mm with “HYACINTHE” at the same point of measurement. One also raises: 3139 mm with Bélouve and 2586 mm with Cilaos.

To note, that one also again establishes world records on 5, 6, 7, 8 and 9 days with respectively 4979 mm, 5075 mm, 5400 mm, 5510 mm and 5512 mm on this same site of measurement of the Commerson Crater.



All in all, on the whole tops of the island, and if one refers to the office pluralities over 4 days, the values of episode GAMEDE are close or higher than what one could observe at the time of “swallowed” HYACINTHE who prevailed of the 15 to 27 January 1980 and which preserves the world records for the durations of 10 and 15 days.


The original text is as follows:

Avec GAMEDE et 27 ans après HYACINTHE, La Réunion bat ses propres records mondiaux de précipitations sur les durées de 3 à 9 jours.



On rappelle que GAMEDE, classé cyclone tropical intense pendant sa phase maximale, est demeuré à moins de 400 km de La Réunion pendant près de 4 jours, avec une zone d’influence extrêmement vaste en terme de vents et de précipitations. Les vents ont été certes forts sur une longue durée, mais n'ont pas revêtu de caractère très exceptionnel. Par contre, les pluies, bien que n'ayant pas connu de pics d'intensité extrêmes, ont été très régulières et très abondantes dans tous les hauts de l’île, produisant par accumulation des lames d’eau remarquables voire exceptionnelles sur des durées de un à plusieurs jours. Des données de pluviographes récupérées a posteriori dans les jours qui ont suivi la fin de l’épisode, ont permis d’établir que des records mondiaux de précipitations avaient été battus.

Après avoir dépouillé et vérifié les dernières données des enregistreurs de son réseau de stations de mesures, Météo-France a ainsi relevé des cumuls exceptionnels entre le 24 et le 28 février :



Sur 24 heures : 1625 mm au Cratère Commerson, approchant ainsi le record mondial officiel de 1825 mm mesuré à Foc-Foc avec le passage de « DENISE » en 1966. On relève aussi 1489 mm à Hell-Bourg et 1295 mm à Bélouve.



Sur 48 heures : 2463 mm au Cratère Commerson, presque à égalité avec le record mondial de 2467 mm d’Aurère datant de 1958. Autres valeurs remarquables : 2358 mm à Hell-Bourg et 2185 mm à Bélouve.



Sur 72 heures : 3929 mm au Cratère Commerson et 3264 mm à Hell-Bourg, dépassant ainsi le précédent record mondial (3240 mm) qui avait été mesuré à Grand-Ilet avec le passage de « HYACINTHE » en 1980. On mesure également : 2824 mm à Bélouve et 2321 mm à Cilaos.



Sur 4 jours : 4869 mm au Cratère Commerson et 3633 mm à Hell-Bourg. Là encore, on dépasse largement le précédent record mondial qui était de 3551 mm avec « HYACINTHE » au même point de mesure. On relève aussi : 3139 mm à Bélouve et 2586 mm à Cilaos.

A noter, que l’on établit également de nouveau records mondiaux sur 5, 6, 7, 8 et 9 jours avec respectivement 4979 mm, 5075 mm, 5400 mm, 5510 mm et 5512 mm sur ce même site de mesure du Cratère Commerson.



Globalement, sur l’ensemble des hauts de l’île, et si l’on se réfère aux cumuls sur 4 jours, les valeurs de l’épisode GAMEDE sont proches ou supérieures à ce que l’on a pu observer à l’occasion de l’ « avalasse » HYACINTHE qui a sévi du 15 au 27 janvier 1980 et qui conserve les records mondiaux pour les durées de 10 et 15 jours.

Since that page gets over-written easily it's best to have a screenshot on-hand:

Two fishing boats with a total of 15 people on board have been missing since February 23rd. Mauritian officials said they lost contact with the boats during Cyclone Gamede.

All I can say is
:eek: :eek: :eek: :eek: :eek: :eek: :eek: :eek:

Think about all that rain in any city in America. Talk about a serious flooding situation. If Hurricane Katrina dumped that much rain on the Gulf Coast, that would make the disaster worse.

Can it be that the story of Noah's Ark originated in La Reunion????

That is more water then the depth of Lake Okeechobee, which right now is running at 10.8 feets.

La Reunion is the real "waterworld!!!"
