Sierra Nevada Highway seems to be having a bit of an adventure!
She left Southampton a couple of days ago for Bremerhaven. A day later she was charging back down the Channel for Southampton; I didn't make a note of the timings but I am sure she didn't have time to get to Bremerhaven and back so must have turned round.
After 5 or 6 hours in Southampton, she set off for Baltimore and was seen heading out of the Channel yesterday.
Now, as you say, she is anchored in Lyme Bay showing destination Brixham Anchorage.
I too thought the gales may have caused her to turn back but why would they change the destination from Baltimore to Brixham if it was merely seeking shelter?
Come to that, why not seek shelter in the Falmouth area?
A couple of days ago, Triton Highway was showing Zeebrugge with an ETA 22/01/09; at this time (Sunday mid-day) she appears to be joining the eastbound channel traffic so I don't believe either the destination or the ETA (I could swim to Zeebrugge in less than 2 months!)
Incidentally, BBC radio and their web site had in interesting article yesterday about how Southampton is being affected. They quoted Honda as having 10,000 cars stockpiled at their Southampton terminal.
And they referred to the car carriers parked off the Isle of Wight.
They also said there are bulkers there which would have cost $250,000 a day to charter can not find any takers at $3,000 per day (no idea how accurate those figures may be)
