NHC New Products


Recommended Posts

A couple things I picked up here at AMS yesterday.

 

Storm Surge Warnings are scheduled to go live in 2015 with testing starting this season.

6-7 day storm tracks from the NHC will be released in text form in an experimental phase and possibly graphic form. NHC is confident in that forecast range but its unclear when the products will ever be fully released. 

 

New storm surge maps and products from the NHC may go experimental this season.

And just for fun.... Knabb said yesterday Sandy may be upgraded to a major hurricane during its time in the Caribbean

Hmmm...verrrrrry interesting!!! Sandy a major, huh? How about it being a hurricane when it Jersey!???!??! Inquiring minds, you know...

Calling it a major when it hit Cuba makes sense-- the data and satellite imagery support that.

Do you think it should be called a hurricane at landfall in NJ? It would be a pretty funny-looking hurricane, if ya ask me. :D

He seemed pretty sure in the Sandy town hall that is was post-tropical. If they were going to make a change, the tenor of his presentation would have been different, IMO.

May or may not.  I think it should be considered.  However, the way it was handled, it likely will not be.  I could definitely see the Cat 3 in the Carib/Cuba.

I'm sure it was.  Probably very carefully scripted IMHO.

Yeah, I was wondering about it, and so I point-blank asked one of the Specialists there afterward.  He pretty firmly said they're not going to re-classify the landfall status in postanalysis.  While of course real-life systems don't always fit into neat categories-- and the space between tropical and extratropical is actually a continuum rather than a precise border-- it seems Sandy was just structurally too far from its tropical roots.

I can buy Sandy's post-tropical classification at landfall based on radar presentation. She did however have an eyewall in the hours not too long before that. Close shave.

 

Yeah, it was really close.  That eyewall feature actually came within radar range, and I remember thinking, "Omg!  They're going to get a real hurricane!"  And then it just went poof!

 

As cool as it looked, though, I heard somewhere that the highest winds were not co-located with that feature.
