Lost lock at start of shift. Relocked quickly and without trouble. Shortly after lost lock a second time; but was unable to relock. Completed initial alignment, after overcoming some difficulty with MITCH_DARK step. Tried relocking but with no success. Breaks on FIND_IR (DIFF) or at CHECK_IR. Also having difficulty with IR DIFF not really found. Can hand tune and get a good spike, but still cannot really find IR with regularity. 

   Winds are up and gusting into the mid-30mph. X and Y microseism is up to 0.3um/s. BRS-X is damping. High winds are forecast until around 22:00PT. Holding the IFO in DOWN until the environment settles before trying relocking. 

   Getting high dust alarms at End-Y. Given the high winds and heavy wildfire smoke, this is not unexpected.
