HILO, HI — The Central Pacific Hurricane Center and Hawaii County Emergency Management Agency activated flash flood watches across Hawaii's Big Island on Saturday as Tropical Storm Moke tracked within 200 miles of the coastline.
Meteorological Forecast and Soil Saturation
Moke, packing sustained winds of 50 mph, is forecasted to track south of the island chain, but its extensive outer rainbands are projected to dump between 8 and 14 inches of localized precipitation across windward slopes from Hilo to Puna.
Emergency officials emphasized extreme caution because terrain across East Hawaii remains highly saturated from Hurricane Lala’s landfall earlier in the week, heightening the risk of landslides along Highway 19 and debris flows in gulch corridors.
Emergency Response and Shelter Activation
Governor Josh Green confirmed that Hawaii National Guard engineering units remain prepositioned in Hilo to assist with road clearance and power restoration. Public emergency shelters are open in Keaau and Honokaa with backup generator capabilities.
