9pm Friday 8/13 Update: Tropical Depression 7 soon to be Grace 00z model guidance has shifted EAST in this guidance package, a trend seen all day today. What does this mean for the southeast ?
Grace will move west in an environment conducive for development and farther east and North than Fred in the Caribbean. This will let Grace strengthen much more and I do anticipate that Grace will pose a threat to the southeast US. 18z GFS ensembles show a strong Hurricane approaching the Florida, Georgia, South Carolina and North Carolina impact zone by Wednesday evening for Florida, Thursday for Georgia or Friday into Saturday for South Carolina and North Carolina.
Fred is moving in the Northern Caribbean and nearing Florida.
Impacts should start to deteriorate for Florida Saturday into Sunday and landfall around Destin and Tallahassee, Florida Monday. Heavy rainfall from Fred will push inland Monday for Georgia and Mississippi, late Monday into Wednesday for South Carolina and North Carolina as a surge of tropical moisture interacts with an lingering cold front.
