The primary thunderstorm hazards will be cloud to surface lightning strikes and strong gusty winds. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY Hurricane Dorian will continue to the west-northwest, reaching the northern Bahamas later on Sunday. Thereafter, there is extremely low confidence in the track forecast for Dorian. The official track takes Dorian northwest, and then northward to just offshore of the Florida east coast beyond Monday night. Heavy rain: weekly rainfall totals may reach 2 to 4 inches with locally higher amounts with the best chance in the Upper Keys. Coastal flooding: the expected southwesterly winds on the southern periphery of Hurricane Dorian may pile-up of water Bay and Gulf side of the Florida Keys. This effect will be greatest across the Bayside communities of the Upper Keys. Compounding the situation, slow moving systems east of Florida tend to back-up the Gulf Stream. Coastal flooding tends to last longer than expected when the flow volume of the Gulf Stream is disrupted. Saltwater flooding of low-lying streets, lots, and docks across the Florida Keys. Stay tuned. .SPOTTER INFORMATION STATEMENT... Spotter activation is not anticipated. APA
