Katherine Hayhoe started the “extreme rainfall” nonsense, which supersedes the catastrophic warming nonsense. It is just as nonsensical.
Fargo, North Dakota had big floods last year, yet there is no indication that heavy rainfalls have increased there.

And the same in England. Met Office figures show there is no increasing trend in average rainfall per rainday.

I grew up near Lubbock, I believe ‘Hayhoe’ was a slang for a country prostitute, ironic.
I could be wrong, all this fear mongering is clouding my memory.
Hayhoe is Mikey Mann in drag.
She didn’t take into account melting snow on a flat floodplain, but then again, snow is a thing of the past, so she didn’t put it in her model.
More to the point, Fargo flooding in 2011 was the result of snow melt in March-April, as it usually is.
The Fargo flood webpage contains a most interesting graphic representation of daily streamflow since the early 1900s

Check out the 1930s – the Dust Bowl definitely reached NDak and stayed for years
That isn’t possible. Climate experts tell us that snow in the Northwest has declined dramatically, so runoff from Montana would also have to have declined dramatically.
The rivers are lying to you. Trust the climate experts.
Fargo, North Dakota, had the worst flood in US history in the spring of 1997 (see: “The Flood Of The Millennium”)

this flood covered more square miles than any previous flood in US history:

“this flood covered more square miles than any previous flood in US history”
Not even close. Your source says 7000 square miles in the US. (Additional in Canada might bring that up to 10,000.) The 1927 Mississippi flood covered 27,000 square miles.
The first known records of floods along the Red River appeared in the 1770s
“Total damages for the Red River region were US$3.5 billion”
And this in a state with a population of only 683,932 (http://quickfacts.census.gov/qfd/states/38000.html)
The Red River Valley is 99% farm land (wheat fields), and yet sustained more than $3.5 billion in damages. That was one hell of a flood! .. I know, I was there!
