So based on NTSLF blue run, so further processed Met0 06Z modelled
atmosphere output and 24 Sep 00Z met data, so likely to change quite a bit.
Dover peak residual of 1.1m at about 22:30 25 Sep and
projected/guestimated peak residual at Newhaven about 0.6m about 01:00
26 Sep.
Guesstimate of about 0.2m residual remnant of the E-W surge, so
observable, at the Newlyn tide gauge a bit after am low tide on 26 Sep


NTSLF black run showing too little E-W surge to survive attenuation down
the Eng Channel, to see on the Newlyn gauge but going by latest GFS
increased area of strong wind over the North Sea, perhaps blue and red
runs today will go higher.
Timings approx GMT and approx surge heights
Dover 22:30 25 Sep, 0.9m
Hewhaven 00:00 26 Sep, 0.35m
Pompey 03:00, 0.22
Weymouth maybe 04:00 , vague hump somewhat lost in the general rough
weather France/England seiching.
Plymouth maybe 05:00
Newlyn maybe 06:00 GMT
