Looking Ahead
The historical flooding event across Kauai continues early this morning, which includes the northern section of the island from Princeville to Haena. As of 2 AM HST, the latest rainfall summary showed the following accumulations for Hanalei over the past 24 hrs: 3-Hr (8.4″), 6-Hr (10.85″), 12-Hr (23.63″), and 24-Hr (28.15″). The previous records from 1905-present for Hanalei include: 24-Hr (12.52″), 48-Hr (24.00″), and 72-Hr (33.06″), which were all three set back in the March 2012 event.
As of this discussion time (3 AM HST), the heavy showers and thunderstorms continue to develop over the same areas with peak rates up to 2 to 4″ per hour, which includes Hanalei. Water levels at the Hanalei River are nearing the 1995 Nov 3rd record of 15.81 ft and continue to rise (currently 14.04 ft).
No significant changes are anticipated through the early morning hours today as a shortwave trough, currently just west of Niihau, slowly lifts northward. As a result, the flash flood watch has been extended across the state through 6 PM HST today.
