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.
