That's a confusing map. Whatever model "TABS" is seems to originate out
of nowhere and shows something hitting South Carolina somewhere near
Charleston. The latest NOAA forecast indicates a model consensus that
Maria will stay well off shore and make a turn to the east, missing the
USA completely. Of course, that could change again tomorrow. I liken
forecasting the direction a hurricane will take to putting a small blob
of mercury on a glass plate. Doesn't take much external influence on
that plate to make the mercury move in different directions.
I started losing faith in these plots with Irma. They had it 100%
going up the east coast 3 days out and in 48 hours it was right over
us. Our local guy was better than NOAA on the last day, predicting the
eye wall hitting within minutes of being right.
