A few readers asked me why I never mentioned anything about the
Lahaina fire. The reason is double:
1) I don't have much to say about it, other that I am obviously
devastated by it, just like any other Maui resident
2) the coverage of the media of this horrible tragedy is so
pervasive and ubiquitous, that I felt it would feel refreshing for
the readers if I kept writing only about wind and waves.
But since this post is now "compromised" from this last point of
view, maybe I will try to add some possible value to it.
I'm far from being an expert of the west side wind conditions, but
in 22 years in Maui I too have experienced that kind of sudden and
extremely strong offshore wind in that area that was the
principal ingredient for the fire to first start (downed power
lines, cigarette butt, other kind of sparkles, who knows), and
then to spread so quickly. The other, of course, was the extreme
drought.
We're all familiar with the fact that the Ukumehame area gets
strong offshores very often. Instead, the strong offshore in the
Launiupoko and Lahaina area are much more rare. Must be a matter
of direction. Below is a satellite image that shows a possible
funnel through the West Maui Mountains. I have no idea what main
direction it takes for that to happen. I'm gonna guess a tad more
north that the usual ENE trades. For sure, that tragic day the
wind was blowing much stronger on that side than on the north
shore (like 50+mph vs 35mph).
Hookipa yesterday.

Medium period NW energy continues at the buoys. Home guess for Hookipa is waist to chest high, bigger in the afternoon windier conditions.
