The latest misinformation from the BBC:
A tropical rainstorm has flooded parts of North Carolina near the coast, leaving homes and vehicles underwater.
Video shows one young man paddling through high waters.
The NOAA Atlas 14 shows that 12 inches of rain fell in 12 hours, which, on average, occurs every 200 years, according to the National Weather Service of Wilmington.

NOAA most certainly have not said that this sort of rainfall only occurs every 200 years on average.
This is actually what NOAA said:

And the NOAA Atlas 14 referred to is clear that the 200 year frequency is based on a single location on the coast, not the region as a whole.
NOAA also state that the high rainfall totals only affected a 25-mile strip of coast:
The coast line from North Carolina to Florida, where these sort of storms can happen at any time, is hundreds of miles long. So the odds of such a storm occurring somewhere on the coast is not 1-in-200 years, probably more like once a decade.
And, of course, rainfall of 12 to 20 inches is nothing unusual in North Carolina. For instance Hurricane Dennis dropped 19.9 inches on Ocracoke in early September 1999, and falls of 10 inches were widespread in the State.
Just two weeks later, Hurricane Floyd arrived, with rainfall totals as high as 15 and 20 inches in eastern parts of North Carolina. 19 inches fell on Wilmington.
Certainly the floods this month were minor in comparison with the devastation wrought by Dennis and Floyd.
But the BBC would like you to believe that events like this latest one never used to happen before global warming.
