315 FXHW01 KWNH 060751 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 351 AM EDT Sat Sep 6 2025 Valid 00Z Sun 07 Sep 2025 - 00Z Sun 14 Sep 2025 ...Eyes on current Hurricane Kiko for possible Hawaii impacts... An upper low is forecast to drop south toward the state over the next few days and lead to some increase in moisture/showers with induction of weak surface troughing. Guidance is quite well clustered for this scenario, bolstering forecast confidence. However, hazardous weather interest is increasingly turning to Kiko and its approach northwestward toward the state into next week with a forecast track just to the north of the Big Island Tuesday/Wednesday when Kiko is forecast to weaken to a tropical storm. Please continue to follow the NHC/CPHC forecast track of the system for the most updated information. Generally, Kiko proximity gives potential to support wind/wave and flash flooding threats Tuesday and Wednesday given tropical moisture potential. Guidance overall agrees to show a return to a moderate trade flow and shower pattern mid-later next week in the wake of Kiko. Schichtel $$
