I assume it will be a meteotsunami associated with a passing cold front.
At least knowing of it in advance will give a chance to grab data about it
http://www.ntslf.org/storm-surges/la...port=Sheerness
and other south North Sea ports .
With anticyclonic general status and lack of isobars, the sea level
should be depressed a bit below nominal 1013mB level.
Otherwise of no flooding consequnce as only neap tides at the moment.
You get so used to surges being developed by low pressure systems and
then west or east suges in the English Channel

Other instances of meteotsunami

more detail of the events referred to in that newspaper article
From the Times, the 1892 event was a double earthquake generated
tsunami, timings of the quake at different stations given, felt in Wales
and whole of the SW .
1929 was meteotsunami associated with anticyclone Azores to Denmark and
heatwave, 95 deg F max in Paris, 87degF max in London.
18degF sudden drop in temperature recorded at Winchester, generated
series of 8 x 12 foot waves at Folkstone and a 20 foot wave Hastings,
Sandown IoW got a bank of sand swept along the seafront.

Both 2015 and 2011 events have been analysed in Weather magazine apparently.
The main amplification suggested for the 2015 event is that the waves
generated by the storm(s) were in shallow water (compared to the
wavelength) and therefore travelled at a speed determined by the depth
which happened to be similar to the speed of movement of the convective
event in the atmosphere.

I've not rediscovered the newspaper details of the 2011
event, "hair-raising" and lightning associated with the tsunami going
over a causeway in the SW somewhere
