Danny downgraded to Tropical Storm, while computer models seem to be going crazy

As of 1:30 PM EDT/AST August 23, 2015

Now Tropical Storm Danny is making its move on its first target, The Leeward Islands.  Already, Tropical Storm warnings are in effect for locations in the northern portions of the islands, along with newly issued Tropical Storm watches for Puerto Rico and the Virgin Islands.  This means that Tropical Storm conditions are possible or are expected over the following few days.

Track/Intensity 

So, where is Danny going?

That is the question most are asking at the moment, although, Danny wont be going anywhere if he doesn’t survive the harsh environment he has moved into.  This, of course, consists of a ton of wind shear created by the El Nino that is expected to gain strength and potentially bring an end to the California drought this winter.  The wind shear was supposed to, at least by now, make Danny a bit smaller and less defined, but viewing the following (as of 1:30 PM EDT/AST), you may see something other than that.

This image shows that Danny is still fighting the wind shear, and although is a bit less defined, is still expanding and has more and more convection towards the center of the storm.

At the moment the National Hurricane Center is one of the lead downers in terms of computer model forecast for intensity.  With the forecast that Danny will fizzle out by the Bahamas, you can begin to imagine the differences that have been created between the OFCL (NHC computer model), and a computer model such as the GNTI computer model, which at the moment as of 12 UTC August 23 2015 suggests a category four hurricane to be off the coast of the Carolinas over the next week and a half.
