Meteorologists are checking to see if a rain gauge on the island of Kauai in Hawaii set an all-time U.S. 24-hour rainfall record. The gauge measured an astonishing 49.69″ of rain over a 2-hour period from April 14-15. At Hanalei, 27.52″ of rain fell in 24-hours – that broke the record for the heaviest 48-HOUR rainfall ever (not just 24-hour).
The Hanalei River rose 10 feet in a matter of hours and was more than 7 feet over flood stage. There were a number of rescues done by law enforcement and the Coast Guard and despite the flooding, mudslides, landslides and road washouts, there were no serious injuries reported. The 49.69″ total would be well above the current record of 43.00″ at Alvin Texas in 1979 from Tropical Storm Claudette. The World Record is 72″ at La Reunion Is. in the Indian Ocean in Jan. 1966, which was also from a tropical storm.
