SHIFT SUMMARY:

Not a great night for H1.  There were winds, but we used to be able to ride through these.  Tonight locks were short and several had the IMC flagged for their locklosses.  And there was one stint where it took the IMC a while to lock.

There was also a M5 EQ offshore from Coos Bay, OR.
