An unusual late season kona low has produced heavy rainfall over portions of the state during what is normally the start of the Hawaiian Islands dry season. This appears to be the latest kona low to directly affect the main Hawaiian Islands in at least the last 20 years. The last impactful kona low in May was during 2002. Kona lows more typically affect the State of Hawaii from November through March. The kona low developed several hundred miles north of Kauai on May 15, then moved west and strengthened on May 16. The main rain band from the system moved over Oahu during the early morning hours of May 16, with cells of northward-moving heavy rain moving over the island over the next 24 to 36 hours. An additional band of moderate to heavy showers moved over Oahu on Saturday, May 18. Impacts mainly included minor flooding of streets in multiple areas of Oahu. A rockslide also occurred near the Pali Highway Tunnels on May 16. Gaged streams indicated elevated flow levels, but none overflowed their banks. The following are notable automated rain gage totals for the 4-day period (96 hours) ending at 4 PM HST, May 19. All amounts are in inches.
