OMG many pages later & EW finally AGREES with me about maountain passes.... What will become of us???

glinda... not naive... there are many studies of cyclonic storms in Central America, Pacific Islands & Carib that back up that mountains do not stop a cyclonic storm, esp the more powerful ones... more like a speed bump, can take some of the force out... but if you are dealing with a storm with Lanes` power... that still equals a potentially damaging storm... & the mountains do not provide a safety net to plan on no effects of the storm, as some would like to believe... they can diminish a storm, yes, but not stop a storm
& those mountain passes, like Waimea, can create a very dangerous area of storm funneling..
ETA: & the frictional forces of the land added to the water vapor taken out by the elevational change does drain storms of their power, but Lane is riding in 29degC waters, that are right nice for fueling a cyclonic storm & if it does ride the edges of our island, the water vapor decrease & friction will not be enough stop the storm... just weaken it....& there is the potential of stalling & all the other tricks of the trade that happen with wall reformations..

Hawaii can produce localized areas of strongly enhanced winds and
rainfall, even well away from the tropical cyclone center.
I guess if the magic mountains don't keep the hurricane away, if it gets close enough the winds can be greater near the mountain.

"As the moving air is pushed over a mountain range it is squeezed between the mountains and the top of the troposphere, causing the wind to speed up. It is nearly always windier, therefore, on mountain tops than in adjacent valleys. The wind is forced over ridges and through saddles, increasing in speed, and making these places more hazardous in stormy weather."
