The peripheral winds of Hurricane Lane are now reaching the big island, Hawai'i.
Kindly recall, hurricanes near Hawaii in general lose strength because coastal ocean water temperatures are less than open ocean waters temperatures. THAT IS NOT THE CASE TODAY.
This is the actual chart of the ocean temperatures surrounding Hawaii. EVERY measure is over average. The usual behavior of hurricanes, as experts might predict, is compromised with Hurricane Lane by unusually warm coastal ocean waters.

There is no continental shelf for Hawaii. That means there is little effecting approaching storms. Hawaii has two worries in regard to such storms as Lane, flooding of low lying land and wind driven waves (including storm surge) that extend inland.

Oahu has significantly more low-lying land compared to Kauai, and consequently hypothetical tropical cyclone landfalls show much more widespread inundation. Under direct impact scenarios, there is the potential for much of Honolulu and most of Waikiki to be inundated, with both still water surge and wave runup contributing. Other regions of Oahu show inundation confined to a more narrow coastal strip, although there is still much infrastructure at risk.
Even for very strong storms in Oahu and Kauai, maximum still water surge is relatively small, and does not exceed 3 m in any storm modeled. In contrast, hurricane waves several kilometers from shore regularly exceed 10 m due to the lack of a continental shelf....
Damage to a structure in Kauai caused by Hurricane Iniki in 1992.
Add potential flying embers of lava and realize my sincere concern for the people there.
I realize there is no PUBLIC ANNOUNCEMENT to cover such a bizarre emergency, so FIND ONE.
