Hurricane Warning for Florida's East Coast

Radar at 5:05pm finally shows a closed-off developing eye southeast of Grand Bahama Island. This is a solid sign of intensification.

The NHC has just issued a hurricane warning for the red-tinted area on the map below.
The storm is forecast to have 80-85 mph winds - with higher gusts - when it gets close to the Florida coast. That should be after about 4pm Saturday. The strongest winds will be to the north and east of the storm's center.

To recap the above map:
  • Red = Hurricane Warning
  • Pink = Hurricane Watch
  • Blue = Tropical Storm Warning
  • Yellow = Tropical Storm Watch 
  • Brown = the area covered by hurricane strength winds (75 mph or stronger)
  • Amber = winds of more than 40 mph (tropical storm force).
Below is the forecast path of the storm.

The Hurricane Center is forecasting the storm to make a second landfall in northeast South Carolina or eastern North Carolina.

Locally heavy rain will accompany Isaias.

Finally, here is the storm surge forecast in terms of feet above mean sea level.

I'll have an additional update later this evening.
