Events cancelled as storm forecast ahead of Scotland’s Euros clash

However the weather remained clear during the morning and afternoon, with fans taking to the streets to party.

Walk north along the banks of the Rhine from Central Station and the route is lined with row after row of portable toilets.

Not pretty perhaps but an unmissable sign of the city’s preparations to host Steve Clarke’s side in their second match of the Euros campaign.

The authorities in Cologne say they’ve been getting ready for this tournament for six years.

Two official UEFA fans zones showing all the tournament matches on big screens have been set up on opposite sides of the river with a combined capacity of around 20,000.

That’s not enough, however, to cope with the numbers expected to arrive for Wednesday night’s match where Scotland fans will outnumber their Swiss opponents by three to one.

It’s led the organisers to create another viewing area capable of catering for an additional 50,000 supporters.
