How did they get all those Gulf & Atlantic position points in 1860 and as far as landfall +/- how many miles of error??

I would guest that they where not that good. In most of them where from unlucky ships or landfalls on land. Its hardly usable pass just showing that there has been interesting times. The early part of the 1900 more ships=more upto date report. But it was not intill 1960s intill we got a satellite. In which case the data has many a hole in it up to the 1960s. Even today a few weak systems get through.

I would think some fish storms were probably missed due to no satellite--all they had was recon and that was only when a storm got close

:roll:

We only have 45 years of good data. The truth is we might not have got a good part of the most seasons before then.

Can you imagine what would have happened to Noel in 2001, no one would have known that a hurricane was shurning near eastern Canada.
