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.

It seems that the s8 CSAT sometimes misses these events – is this the high-wind-speed-error that Sean saw several years ago?
