The surface wind was 220deg/20kt and they were heading 122deg/80kt i.e. almost all right crosswind which explains the track shown in fig 6 of about 110deg. The transcript notes the pilot saying "groundspeed gonna start increasing", I wouldn't have thought by much as it's almost all crosswind.

The aftercast says 300' cloud base, and their baro altimeter was indicating 300'. So they would have been just in/out of the bottom of it at 200' radalt with mostly downward visibility. But I would have thought at that short range, even if the light was 80' deep in cloud, the white light of the lighthouse would have lit them up like a christmas tree at least once before they finally saw the rock maybe a second or 2 before impact (they were on the seaward white side of the lighthouse).

I'm surprised the pilot said nothing in the last 14 seconds of the recording, 9 seconds of which was post impact. I suspect the "we're gone" comment from the co-pilot came about one second after they hit the rock, which were the last words recorded from any crew member.
