While the UK is currently experiencing relatively benign weather for the time of year, extreme conditions are expected in some other parts of the world.
Morocco and Spain
Last Saturday, Agadir in Morocco saw 90mm of rain fall in just 24 hours, which is around twice the monthly November average for the region of just 50mm. The subsequent flooding resulted in more than 30 fatalities.
Unfortunately, more severe weather is expected through Friday and into the weekend across Morocco, but particularly around the southwest of the country.
A combination of a deep area of low pressure, relatively warm sea temperatures and strong winds will bring heavy rainfall. 100-150mm of rain could fall across SW Morocco on Friday with further heavy rain likely on Saturday, and totals could be enhanced over higher ground. Conditions should improve into Sunday.
Through the weekend, the same area of low pressure is expected to bring very heavy rain across North East Spain. Rainfall totals for both days could reach 150-300mm, locally 400mm over higher ground, with a gradual improvement into start of next week.
Both areas could experience flooding and landslides from the intensity and duration of rainfall, as well as the rain that has already fallen in recent days.
North East America
A rapidly deepening area of low pressure is bringing heavy rain and snowfall across parts of the Eastern Seaboard of North America, with the storm quickly moving northeast over the coming days.
The weather has been caused by an extreme temperature contrast between the warm weather of the Gulf Coast and the bitter cold across inland parts of North America.
While heavy rain is expected on the coast, snow is likely inland, mainly but not exclusively over higher ground. As tomorrow is Thanksgiving, this system poses a risk of travel disruption to what is normally one of the busiest holiday periods in the States. Over 4 inches of snow could fall over parts of the northeast, before the weather improves into the weekend.
There is absolutely nothing unusual about any of the incidents described in this article. They are simply the result of natural variation and the data shows that there is not one shred of evidence that the weather (or climate) has become more “extreme”, a term more appropriate to tabloid journalism.
I am still waiting in vain for the Met Office attribution guru Peter Stott to produce data to support his ridiculous claims back in January that the Somerset floods were the result of global warming. Come on Peter, lets see the data to back your claims, otherwise some people will be justified in concluding you were not being truthful.

But it is it unusual? 😉
I’m watching the nor’easter event closely as well, although the air maybe still a bit too warm to cause widespread problems as that low tracks up the east coast.
I would have liked to see the rainfall totals for Morocco to comment on, but unfortunately they don’t include rainfall totals in their observations!
