Please note- there are
some obvious errors in this data. Most notably in
the category of wind gusts. If we had experienced
a 137 mph wind gust, the station would be gone!
The erroneous data happens during times of heavy
rain. Something causes wind readings to spike
during heavy downpours, I suspect there is a bit
of cable shielding that has been exposed
somewhere in the system, pehaps by a hungry
squirrel. When water hits it, it reads as a wind
gust. In any event, all other readings like
temperature and barometric pressure etc, should
be quite accurate.
