Currently in East Antarctic I am seeing two high-pressure domes with 1060mb and 1067mb, resp. (I didn't think such pressures are possible on Earth). In West Antarctic I am seeing domes labeled 'H', with 998mb and 991mb. which seem too low. (I have the Pressure switch enabled)
Is this a bug?
I have screen shots which I can send you.
I am also in Tonga and have a similar question... The forecasts are occasionally off, but also I notice that the NEMS forecast seems to be offset by time quite a bit from the other two, ahead by a day or so...
