The MIA AWIS was U/S at the time.
Sorry, I missed that bit.
One other thing not mentioned for ops control, was that ATC could look at the actual wx and put their own requirement on it that was contrary to the forecast. I don't remember TTFs being in operation prior to ops control closing down.
"Adelaide requires alternate due unforecast fog, ATC operational requirement, Perth, Alice Springs suitable, advise alternate, endurance remaining etc"
