Hurricane Olivia Threatens Hawaii with Flash Floods

Hurricane Olivia Threatens Hawaii with Flash Floods

At 11 a.m. HST on Saturday, Sept. 8, 2018, the center of Hurricane Olivia was located about 1025 miles E of Hilo and 1190 miles E of Honolulu (near latitude 21.7 North, longitude 139.4 West).

Meanwhile closer to Hawaii, Tropical Storm Norman continued to move north-northwest away from the islands. The still-Category 2 storm was moving west-northwest at 15 miles per hour as of Friday evening. The system is projected to take a slight west-southwest turn Monday night into Tuesday.

Forecasters say Tropical Storm Florence has turned into a hurricane and is swirling toward the East Coast for what could be a direct hit toward the end of the week. "Florence is forecast to rapidly strengthen to a major hurricane by Monday, and is expected to remain an extremely risky major hurricane through Thursday", the advisory says. Commercial ports are Hilo Harbor and Kawaihae Harbor on Hawaii Island, Kahului Maui and Barber's Point, Honolulu Harbor, Kalaeloa, and Kewalo Basin on Oahu. "I can't find another example of a hurricane/typhoon nearing Guam, Hawaii & the eastern United States at nearly exactly the same time (days ~ 4,5,6 respectively)".

School closures may be expected for midweek, similar to what happened with Hurricane Gordon in the southeast USA, given the potential for another foot or more of rain.

Hawai'i County will not be distributing sandbags until active flooding occurs.

It's approaching the islands from a completely different direction than last month's Hurricane Lane, which dumped record amounts of rainfall on the Big Island.

Tropical storms have a history of causing major damage in Hawaii.
