Just a quick note that s8 has routinely seen winds >20 m/s, with the highest 5-min average of 27 m/s on 17 Mar.
s15 is the next windiest, up to 17 m/s, though I suspect that s17 would have been high as well if it were being recorded.
The pattern is not surprising, though the magnitudes are rather high for what ISFS normally sees.
