Apparently we're in the midst of a meteorological phenomenon.
All I know is that it means I get to sit in the pub, by the river, enjoying a delicious pint, some lovely sunshine and get gently refreshed by a most pleasant warm breeze.
And then eat cheesy garlic bread and cheesy chips. Not sure if that is strictly speaking a side effect of the Spanish plume though.
