This significant meteorological event occurred from January 7th to January 8th, 1966. The measurement was made using a tipping-bucket rain gauge, a standard instrument for recording precipitation. The WMO's review in 2010 confirmed the validity of this record, solidifying its place as the benchmark for extreme daily rainfall.
Such intense rainfall events are rare but highlight the potential power of weather systems and the need for accurate monitoring and data collection using reliable instruments like the tipping-bucket rain gauge.
