A hurricane clock was released for some parts of the Florida coast on Friday as Hurricane Isaias targeted the state of the Sun.
Isaias – a Category 1 hurricane with winds of 75 mph – was located 295 miles southeast of Nassau and moved north-west at 16 km / h, from 11 a.m. advising from the National Hurricane Center. It is projected to remain a Category 1 hurricane through the Bahamas, as it moves along or parallel to the east coast of Florida, and then eventually across the east coast by early next week.
A hurricane hour, meaning storm conditions are possible, has been released for parts of Florida̵7;s east coast from north Deerfield Beach to the Volusia-Brevard county line. A tropical storm warning was issued for the Florida coast north of the Ocean Reef to Sebastian Inlet as well as Lake Okeechobee.
A hurricane warning is in effect for the Bahamas, and a Tropical Storm warning for Turks and Caicos.
As Hurricane Isaias closes in Florida, the state can expect tropical storm conditions until Friday evening in the form of dark winds and rising tropical inflows. The big question mark for Florida remains whether Isaias will make landings in the state this weekend or stay alone offshore. Despite the rainfall, heavy rain and strong winds will be possible on Saturday and Sunday along the entire east coast. From Monday, 2-4 inches of rain can fall, with rainfall of up to 6 inches at some points. How much rain will eventually fall will depend on how close the storm center gets to Florida.
However, before Isaias arrives in Florida, it will collapse parts of the Caribbean and the Bahamas on Friday with strong winds and major falls.
Tropical storm conditions continued across parts of the Dominican Republic, Haiti, and Turks and Caicos on Friday morning. Hurricane conditions were expected to start in the southeastern Bahamas until late Friday morning and will spread to central and northwestern Bahamas by Friday afternoon. A dangerous storm surge is projected to raise water levels 3 to 5 feet above normal tidal levels in offshore wind areas in the Bahamas. In terms of rainfall, the Dominican Republic and northern Haiti can take 4-8 inches, with a total isolated maximum of 12 inches while the Bahamas and Turks and Caicos take 4-8 inches. These amounts of rainfall will lead to flame floods, landslides and river floods.
For the Bahamas, Isaias comes less than a year after Hurricane Dorian hit the island chain for a relentless period of more than 48 hours.
Even as Isaias affects the Bahamas and Florida this weekend, meteorologists will be following the storm through the middle of next week.
Heavy rain associated with Isaiah is forecast to affect North and South Carolina early next week. Rain and wind could then affect the shores of the Mid-Atlantic and Northeast on Tuesday and Wednesday.
Isaias is a fairly large storm, so even if the center of the storm does not cause it to fall to the ground, a proximity to the coast can bring significant impacts. Hurricane-force winds lie 35 miles away from the center and tropical winds with hurricane force 205 miles away.
According to Phil Klotzbach, a hurricane specialist at Colorado State University, when Isaias became a hurricane, it became the first time on record (going back to 1851) that the Atlantic Basin had two hurricane formations in the last week of July. This comes on the heels of Hurricane Hanna, which made landfall on the Texas coast on July 25th.
