Apparently wind is still an issue.  After a brief lull, sustained winds are back above 40 mph.

Under such high sustained wind speeds (>40 mph), I would recommend switching the beam-direction rotation loops on Stage 1 ISIs to 90 mHz blends instead of the 250 mHz blends. This is not automated, I think, so you may have to do it by hand for each chamber: rX on ETMY, ITMY and rY on ETMX and ITMX. Jim and Rich had showed that this was helpful under high winds.

I texted Jim for some more advice related to Krishna's suggestion.  He informed me that he is on his way to the site.  I will wait for him to arrive before making any changes to the SEI configuration.  Stay tuned.
