Between August 22 and 28, Hurricane Lane battered the Hawai'ian island chain with high winds and record rainfall, ranging from 52 inches on the Big Island to just under 10 on O'ahu. People are still digging out and the soil remains saturated. Now, some two weeks later, the state is once again bracing for the onslaught of a major storm.
Hurricane Olivia, as of this morning, is about 650 miles from Honolulu. Still rated a Category 1 with sustained winds of 85 mph, it is expected to weaken into a strong tropical storm by the time it begins to affect the islands. A tropical storm warning has been issued for the islands of Hawai'i and Mau'i, and a TS watch for O'ahu. The storm will begin to affect the state Tuesday, with high winds and heavy rainfall. While not as much as Lane, it will nonetheless be an an unwanted 15" to 20" addition to areas on the Big Island that experienced some 52 inches of rain less than two weeks ago.
Governor David Ige has declared a state of emergency and local and state officials are urging residents to prepare. Working at Target last night, I did see a slight increase in water purchases, but considering that folks really stocked up for Lane, it seems as if everyone is about ready. The only task remaining is to remove loose items from around the houses and properties. For this island, the forecast is 40 mph winds and 4" to 8" of rain. Mau'i and The Big Island may get as much as 20" of rain. Complicating matters is that the storm has slowed from 15 knots to around 8 knots and is expected to slow even more, which means that the effects of the storm will linger much longer, increasing the risk of flash flooding and landslides.
Now this situation is passing almost undetected by the rest of the country because a truly monster storm, Hurricane Florence is expected to make landfall in the Carolinas as a strong Category 4, perhaps even a Cat 5, affecting an area ranging from Georgia to Washington DC. The storm will push inland, bring torrential flooding rains as far as the Ohio Valley. Tens of millions are in the threat cone for this storm, and since the media capitols are all in that area, Florence will occupy the nation's attentions. But while Olivia is a far less powerful system, it is nonetheless poised to impose significant damage to Hawai'i.
