It's weird how T.S. Bonnie weakened as it approached the South Carolina coast. Or maybe not so weird. Last year's T.S. Ana officially dropped from 60 m.p.h. to 45 m.p.h. as it approached the South Carolina coast. I'm not aware of any land-based station that recorded tropical storm force winds.
Now why would the NHC consistently overestimate the windspeed of tropical systems by 10-15 m.p.h.? And wouldn't such overestimation lead to more and earlier named storms?
While conspiracy theories are fun, they are not always based in fact. The warm Gulf Stream current was accurately predicted to strengthen this storm as it approached the U.S., while cooler waters closer to the continental shelf, wind shear and interaction with land were expected to weaken the storm.
There are no black helicopters in the grassy knoll for the storm system formerly known as TS Bonnie.
