For Florida, just a handful of miles may make a huge difference in
Hurricane Dorian's slow dance with the coast.
The National Hurricane Center forecasts Dorian to be 40 to 50 miles off the
Florida coast on Tuesday and Wednesday, with hurricane-force wind speeds extending about 35 miles to the west.
It could be within 100 miles of that point, which is why the hurricane center uses — and emphasizes — a shaded cone of uncertainty.
