Map of the region in central Vietnam affected by the tremendous rainfall of November 2-3, 1999. The streets of downtown Hue were swamped under 3 meters (10’) of floodwater. Nearby, the city of Hue was inundated with 1,422 mm (55.98”) in the same 24-hour period resulting in floods that killed at least 622 and destroyed 42,000 homes. There is a mention of a 1,672 mm (65.83”) 24-hour precipitation figure at Xinliao, Taiwan on October 17-18, 1967 in some Chinese publications, but this figure is unofficial and dubious.Ī very close second to the Isla Mujeres figure is a little reported event that took place in central Vietnam on November 2-3, 1999 when 1,630 mm (64.17”) of rainfall fell on Truoi. Outside of Reunion Island the world record for a 24-hour rainfall is the 1,637 mm (64.45”) that fell on Isla Mujeres (an island of the coast of the Yucatan Peninsula), Mexico on October 21-22, 2005 during the passage of Hurricane Wilma, the most intense tropical storm ever observed in the Western Hemisphere. This record has been discounted by Meteo France. Paulhus in a Monthly Weather Review article published in 1965 (Vol.

There is also an unofficial 24-hour total of 1,870 mm (73.62”) at Cilaos on March 15-16, 1952 that is cited by J.L.H. It is generally acknowledged (and officially accepted by the WMO) that the greatest 24-hour rainfall record also occurred on Reunion Island at the site of Foc-Foc on January 7-8, 1966 when 1,825 mm (71.85”) on rainfall was measured during Tropical Storm Denise.

Map from ‘Monthly Weather Review’ article by Alain Barcelo et al.Ībove is a table of the 7 a.m. The back circles indicate the location of official Meteo France rain gauges and the numbered squares the gauges used in the research project. The Baril transect is where the heaviest rainfall apparently occurs on a regular basis on the island. Geographic location of rain gauges on the Piton de la Fournaise massif used in the study. Nevertheless, the equipment used in the research project was of exacting standards and the measurement at Baril 1600 was in line with other measurements made in the region during the event. This may be the reason that the WMO has not accepted the Baril 1600 reading, since the gauge was not part of the official Meteo France (French Meteorological Organization) rain gauge network on the island. The article states that the rain gauge at Baril 1600 was part of a 5-year investigation of water resources on the Piton de la Fournaise massif on Reunion Island undertaken by the University of Reunion Island. This rainfall event was the subject of a scholarly article in the December 1997 issue of Monthly Weather Review, Vol.

However, the WMO committee does not appear to have been aware of (or dismissed) an even greater 48-hour total that also occurred on Reunion Island on February 27-Mawhen a site identified as Baril 1600 (the 1600 refers to the site’s elevation of 1,600 m/6,300’) measured 3,000.5 mm (118.13”) during an intense generalized rainfall event associated with Tropical Depression Hutelle that affected the island from February 27 to March 5 that year. Previous to the now officially recognized Cherrapunji 48-hour record mentioned above, the previous record was thought to be 2,467 mm (97.13”) set on March 15-17, 1952 at Cilaos, Reunion Island, a French territory in the Indian Ocean. However, this may not be what was truly the greatest 48-hour precipitation record. The figure is said to be an amazing 2,493 mm (98.15”) at Cherrapunji, India that fell on June 15-16, 1995. WMO (World Meteorological Organization) recently announced that a ‘new’ world record for a 48-hour (or two day) period has been confirmed following an investigation by a group of climatologists from around the world.
