By the century’s end the heaviest days of rain and snowfall across much of North America will likely release 20 to 30% more moisture than now. Much of the increased precipitation will occur in winter, potentially exacerbating flooding in regions like the upper Midwest and west coast. Heavy precipitation days historically experienced once in a century will become more frequent–as often as once every 30 or 40 years in the Pacific Northwest and southeastern U.S. People will be more affected by the really rare and most extreme events, because those are showing the biggest increase. The so-called once in a century storm that hit Ft Lauderdale was a misnomer.
