Puerto Lopez Columbia Rainfall

A WMO international panel of meteorologists and climatologists from Argentina, Colombia, France, Germany, India, Morocco, Spain and the United States has recently completed an investigation of two potential world record extremes. First, an assessment of the precipitation record at Puerto Lopez, Colombia was conducted to ascertain if that location could be established as the highest annual precipitation recording location for the Earth. The committee recommended (and the WMO Rapporteurs accepted) to not accept at this time the Puerto Lopez extreme as “highest annually averaged precipitation” extreme. This is based on the assessment that the Puerto Lopez location did not meet WMO guidelines for establishment of a 30-year normal for the period 1981-2009. Consequently, the WMO is leaving the category of “highest annually averaged precipitation” extreme vacant at this time. If more data from Puerto Lopez or another claimant for this extreme is brought to the attention of the WMO, a new evaluation committee may be established. Second, this international panel of meteorologists and climatologists has assessed the precipitation record at Cherrapunji in India on 15–16 June, 1995. They have recommended (and the WMO Rapporteurs accepted)the rainfall record accumulated during this 48-hour period as being the new "highest 48-hour precipitation for the world." The accumulated precipitation during that 48-hour period at Cherrapunji was 2493mm. That exceeds the old WMO recognized extreme value of 2467mm which occurred at Aurère, La Réunion on 7-9/4/1958.
