Just when we thought it was summer...

...here comes Storm Hannah, carrying 140km/h gusts, prompting the Irish weather service to issue a 'Red Warning' - the highest category of risk.

Hannah reaches Ireland.  In five hours, it will hit Wales.

As previously noted, the increasing 'waviness' of the wind flows is now bringing periods of very warm weather as hot air floods in from the south, followed some days later by cold weather flooding from the Arctic.  This is all a well-predicted consequence of the reduced difference in temperature between the Arctic and more southerly latitudes.

I'm afraid that, in coastal Wales, we are very much now feeling the impacts of climate change.  All antennas down, and there will be little sleep tonight.
