The increase of intense storms is attributable to global climate change -- the water is warmer, the air is warmer, and there is about 5% more evaporation, and there is more heat energy driving the weather. There is significantly more lightening, and there are more intense rains and more intense snows, more intense droughts -- and droughts that have become the norm. The tundra has been on fire from lightening strikes, and it burned all around Moscow this summer; where they saw temperatures above 100F for the first time in history.
Last winter, there was a snow storm where the trailing edge was in Iowa, and it started snowing here in eastern Massachusetts. That is close to 1,000 miles of one single storm system. This fall, there was a storm that spanned from Alabama to Alberta (more or less) and it set a new all time record for the lowest pressure every recorded.
Now we hear about super-cyclones -- there was one this past summer that had sustained winds about 180MPH and top gusts just shy of 200MPH. There were more massive floods all over the USA where they have almost never been. Downtown Memphis Tennessee was under 10 or 15 feet of water. Oklahoma got severe floods, as did Wisconsin and Michigan; along with many more tornadoes than are usual. While I was at the X-Prize in June, there were many tornadoes all around during that weeks and before and after.
It used to be pretty amazing to hear about 1/2" of rain in an hour, and 1" per hour was an utterly staggering amount of rain. Now, we pretty regularly hear about 3 1/2" in one hour.
And yes, places like Pakistan and Vietnam get 30+ inches of rain in a few days. The Pakistan flood was about one years of rain (in an average year) in a few days. One fifth of the country is utterly devastated, with virtually every bridge, road and building destroyed, in the affected areas. About 20 million people are homeless. Entire crops were wiped out, and they will not be able to plant those lands for at least several years.
Have you ever heard of such a thing before?

Edit: how much snow so far there in merry old green UK?
