Hurricane Dorian is now a monster Category 5 hurricane with winds now 160 mph. This storm is a serious threat to Florida by Labor Day and Tuesday. After that, it will move very slowly, and is looking more likely to track northward toward the Carolinas.
It's quite clear that Dorian will continue to move west toward Florida through Monday. It may not directly hit the Florida but rather brush the coast with wind and rain. It is expected to show down as it approaches Florida and hopefully turn north before reaching Florida. Either way, a very strong storm will be heading their way by Labor Day into Tuesday.
The slowing motion will put more wind and rain over Florida for Monday, Tuesday, and possibly even Wednesday. After that, it's likely that the storm will start to track north and northeast, in the general direction of the Carolinas.
It's possible that the storm will move right along the southeast coast all the way up toward the Carolinas, which could make for a rough storm for the SC / NC beaches.
