Atlantic update (Florence, Isaac, Helene)

Of course most of the attention is on Florence, but Isaac is out there headed towards the Caribbean.  Fortunately it’s not well organized, and expected to fade out over the mid Caribbean sea.  Helene is way out there and likely to head out into the ocean.

Florence, on the other hand, is rapidly intensifying as expected.  Here’s the view at 11am, classic hurricane structure …

The forecast is still pretty grim for the Wilmington NC area, and didn’t change much from this morning.  Evacuations have been ordered for the Outer Banks as of noon, and expect further evacuation orders to be announced in North and South Carolina this afternoon.  NHC plans on issuing watches tomorrow (a watch is issued 48 hours before tropical storm or hurricane conditions are expected).  Here’s the 11am NHC track and Haetta/TC estimated impacts …

On this track and intensity, the model gives economic impacts of $25 to $30 Billion dollars, which would place Florence in the top ten for damage.  You’re going to hear a lot of hyperbole about this storm, but that doesn’t mean it isn’t a very dangerous system.  If you are in the potential impact area, listen to the guidance of your local emergency managers and take appropriate action.
