Today's Met Office FAX chart (1200) shows a High south of Newfoundland with central pressure 1051 mb. Does anyone know if this is a record for an Atlantic High or if not, what the record is? It's certainly the highest I have seen.

I have the gridded data back to 1948 at least, it just needs some code writing to search and list the extremes.

In the mean time I found this PDF that has a mid- Atlantic January high from 2003 of 1057 hPa!

Thank you very much, Bruce. I'd simply forgotten about the 1057 mb in 2003. This is extraordnarily high, higher than anything recorded in the UK and at a latitude south of most of it.
This has prompted me to dig out some old Weather magazines (mine go back to 1981) which of course I should have done in the first place. Thanks again.
