NE of Azores Islands : INVEST 92L

[HURAKAN]

this is ANA IMHO

The NHC has already said that it had acquired some tropical characteristics, which in my book says subtropical.

This low is not a real tropical system over warm tropical waters. But what is the different to storms as Zeta or Epsilon? SSTs were some degrees higher with Epsilon and Zeta, but all are partially convective systems with some tropical characteristics. So I think it should be ANA.

Is there any ships or bouys out there to get surfaec radings from this system????????

[HURAKAN]

Thanks Daniele for those images. I continue to be amazed by this system. Quite impressive.

Guys you keep talking about a subtropical storm, but this sistem for me, today, does not have many subtropical characteristcs..and It is cleare that this is not extratropical storm.
If it had to be classified it should be called Tropical Storm, and not Subtropical Storm.
Even though the nhc does not classify it as a tropical storm, for me this is a Tropical Storm.
Keep my point

[HURAKAN]

Daniele, the problem is that 92L is over SSTs in which it will be very difficult to develop a tropical cyclone. Therefore, it may look tropical but because of its origins and SSTs, I think it's subtropical.

[Cyclone1]

Well, there's more to topicality than just appearance. Technically, Andrea was still extratropical in that image.

This storm is beautiful.

I'm no expert, but in my opinion, this is a tropical storm.

I've reluctantly added a wx chart floater to Active Storms.

I'm still on the fence about this one. I'm still leaning toward subtropical storm. While I'm not a fan of naming those types of systems, I'm surprised the NHC (who, in my opinion, tends to name storms liberally) hasn't upgraded this. This is really no different than several other systems over the past few years.

I have to agree here.

Especially since its been persisting for over a day now.

[cycloneye]

They for sure will analize it at post season.

It loooks more and more like a Hurricane

[Macrocane]

I still don't understand why it hasn't been named. It has a close circulation, the convection is weak but I have seen other tropical systems with the same appearence due to high latitudes, it's not cold core and it is producing winds higher than 35 kt. For me is at least subtropical, maybe we will have to wait until post analysis.

AMSU (Advanced Microwave Sounding Unit) is now avaliable for 92L and for what I understand it shows a warm core too, at least this morning (7:14z)


Channel 5 (550 hPa)





Channel 6 (200 hPa)

this is ANA with an eye in my opinion

Let me add that much worse looking systems similar to this have been named.
