US could see extreme rain increases by end of century

The study, in the journal Nature Climate Change, suggests that storms that now occur about once a season could happen five times a season by the century’s end, a 400% increase.

And when such storms do occur, they could produce up to 70% more rain. That means that an intense thunderstorm that would today drop about 5cm (2 inches) of rain would drop 9cm in the future.

Such massive amounts of rain occurring more often could put significant strain on infrastructure that already struggles to deal with heavy rainfall, as seen across the country this year in places from Louisiana to West Virginia.

Large heavy downpours have already been increasing across the northeast. This pattern will continue is a more broad area across the United States. Heavy downpours like this can cause serious infrastructure damage.

The Midwest seems to be pretty stable on the increase in heavy rains. On the outer portions on the United States is where we see the most dramatic increases by as much at 70%.  The study has proven if greenhouse emission continues on their current path. these severe storms will follow across the lower 48 states.
