IFO is LOCKING at INITIAL_ALIGNMENT

H1 was doing an initial alignment when I entered. Wind speeds are extremeley high (50mph), with microseism increasing in the last 8 hours.

We will likely not be able to lock until wind calms down, which is only forecast to happen in a few hours/once wind gets below 30mph.
