Kauai Experiences the U.S. 24-h Precipitation Record
Kauai Experiences the U.S. 24-h Precipitation Record: ...Cliff Mass Weather Blog.
But additional precipitation records have become available and it now appears that the precipitation in some locations went beyond extraordinary, producing 24-h amounts that have never been documented anywhere in the U.S. at any time: the all-time 24-h precipitation record of the United States.
That is something amazing.
This week the National Weather Service released a special statement that a rain gauge in Waipa, about a mile west of Hanalei, on the north side of Kauai, received 49.69 inches...1262 mms.... during the 24 hours ending 12:45 PM HST on Saturday April 15th (that is 2145 UTC/GMT). As an aside, the message was written by Kevin Kodama, the NWS Service Hydrologist in Honolulu, and a graduate of the UW Atmospheric Sciences department).
An official review team will evaluate the quality and consistency of the rain gauge data to determine whether the record was actually broken. This was not an official NOAA rain gauge but one installed by the Waipa Foundation. If true, the April 14-15th total would smash the previous U.S. 24-h record of 43 inches observed in Alvin, Texas on July 25-26, 1979.
