(BIVN) – The Flash Flood Watch continues for all Hawaiian islands through late tonight.
“Deep tropical moisture along with a strong upper level trough is expected to produce heavy rainfall and possible flash flooding,” the National Weather Service reported this morning. “The most intense rainfall and highest risk for flash flooding will be from Kauai to Maui County today. The flood threat for the Big Island will be greatest this afternoon and tonight.”
According to a morning Hawaiʻi County Civil Defense message, police report all roads are open at this time. “State Highway crews are clearing a small landslide on Highway 19 near mile 15, be cautious for equipment and workers on the roadway,” civil defense said.
On Monday night, heavy rains closed Highway 11 in both directions due to water on the roadway between mile marker 54 and mile marker 57 in the vicinity of Punaluʻu. Road closures also occurred on Ponahawai Street and Kamehameha Avenue, Pauahi Street and Aupuni Street, and Kamehameha Avenue and Manono Street in Hilo.
“Do not cross fast flowing water in your vehicle or on foot,” the emergency officials reminded. “When lightning occurs the best place to be is indoors.”
“Heavy rainfall could result in low spots in roads becoming dangerous and impassible due to severe runoff,” the National Weather Service said. “Debris in streams and gulches could clog bridges and culverts resulting in dangerous flooding. Isolated landslides could also occur.”
