how often does a 74 to 110mph system get beyond 40 degrees north?

I see they've now knocked it back to an S rather H above 40 deg N.

Up to 45 deg N , H 75mph system , heading for Iceland, projected track
currently, or mid Iceland/Scotland on GFS and Reading ,Navgem,Gem &MetO
going for N Scotland .
2006 ex-hurricane Gordon with the mid Iceland/Scotland track induced,
despite closest approach of 480 miles a .5m surge in the English
Channel. 21/22 Aug 2017 is, for summertime, a period of unusually high
spring tides.

The GFS 00Z forecast of Gert tracking ESE across N Scotland into the
North Sea on the 21st could be troublesome if it happens to be correct
since 21st is a new moon.

Biggest tides not until 23rd though, not particularly big on 21st.

Magic Seaweed, which is partly based on GFS, shows nothing of note swell wise http://magicseaweed.com/UK-Ireland-S.../1/?type=swell

Mind you, it's the 22nd when there's more of a N Sea surge setup, and the tides are bigger that day.

Still not much of an actual swell forecast though.

Not much sign of a good Atlantic swell for a while either, basically just a mess. http://magicseaweed.com/Sennen-Surf-Report/4/ Fast moving ex hurricanes affecting a very limited area normally just aren't up to it. A nice, large area stationary low in mid Atlantic with a UK ridge is what's needed, and that has been rather lacking. Still, just OK for the Boardmasters, if very messy http://boardmasters-86b4.kxcdn.com/i...highlights.jpg

Model projections swinging about a lot still.
Was this a "SAS" sewage situation?

It would also appear that he had probably been in contact with someone else with the condition before attending the festival.

However, this is a disgrace. http://www.cornwalllive.com/sewage-d...ail/story.html

Sewage 'overflow' discharges at Gwithian are becoming the norm every time there's a sharp shower. There were no problems until the famouse 'clean sweep' upgrade.

There's a very useful SAS Sewage Discharge App. https://www.sas.org.uk/safer-seas-service/
