With the passage of TD Ian 18/19 sep relative to the UK ,when the tides
are in the top 2% of their predicted range. I'm reminded of the stealth
tide we got in the channel with the passage of Hurricane Gordon ,
closest approach 480 miles away.
By stealth I mean absolutely benign and stable air pressure in southern
UK , but as neap tides then, the surge in the channel was of no
significance. But a repeat of the Gordon passage would mean house
floodings around here, going on top of the very high spring tides then.
Of course if Ian comes more eastward , then even more problem.
I,m revisiting previous flood events , via synoptics and wind
stress+inverse barometer calculations to get some sort of early idea of
any significant surge possibility, and the movement over 6hr of the
synoptics makes it a lot easier than 12 hour

Many thnks, looks promising, unfortunately my fumblings finding valid
codes meant
"Sorry, Your quota limit for slow queries rate has been reached"
so I'll try later now I have one code at least

Sorry, I should have said synoptic charts, 6 or even 12 hourly, for
"our" bit of the Atlantic

I found the charts at this section
http://www.ogimet.com/gsynop.phtml.en
along with wetterzentral daily archive I can probably graphically
conflate them together , well enough for my purposes
