(BIVN) – As Hawaii Island remains under a Hurricane Warning due to the slow approach of Category 4 storm Lane, a Flash Flood Warning has also been in effect for hours in East Hawaii.

“At 9:26 a.m. HST, radar and rain gages showed heavy rain continuing from the windward Kohala slopes to South Point,” the National Weather Service stated. “The highest rain rates were 1 to 2 inches per hour over the South Hilo and Puna Districts. Akoni Pule Highway is closed at mile marker 24. Honolii Stream and Wailuku River are running very high. Additional rainfall will move ashore over the next several hours.”

Multiple roads and streets are flooded, and there are numerous road closures.

Between 9 a.m. and 10 a.m., Big Island Video News recorded video of the flooding that closed E. Kawailani Street from Awapuhi Street to Nohona Street.

The Hilo Bayfront area is also under water. The Bayfront Highway remains closed, and a huge pond has overtaken Pauahi Street between the soccer fields and Wailoa State Park.

The Wailuku River is swollen and raging. Officials say the river overflowed a bit overnight and deposited debris onto Carvalho Park.

At 9:51 a.m. HST, the National Weather Service in Honolulu reported:

Deep tropical moisture surrounding Hurricane Lane continues to surge north and west with heavy rains extending over 300 miles from the center of the hurricane. Flash flooding has already been reported at several locations on the Big Island during the past 12 to 18 hours. Expect increasing shower coverage and intensity as Hurricane Lane approaches the islands. This has warranted the renewal of the Flash Flood Watch for the entire State of Hawaii through Saturday. Flood Advisories and Flash Flood Warnings will be issued for local areas as the heavy rain threat persist and intensifies.

Life threatening conditions will be on the rise in the next 12 to 24 hours as Lane draws closer to the islands. Expect not only damaging winds, but also dangerous surf, coastal storm surge as well.

The potential for tornadoes and waterspouts increases as Lane nears the islands. These threats will be included in the TCV and HLS products from Oahu to the Big Island. We will be able to better refine the threat as Lane approaches each island.

As of 8 AM HST, Hurricane Lane was located roughly 200 miles southwest of Kona, moving northwest at 7 MPH. Based on the latest CPHC forecast, the center of Lane will pass roughly 110 miles west of Kona Friday morning.
