Looking more tropical than sub-tropical

Interesting language by Lawrence who is indicating that for the time being it will stay sub-tropical but it has detached from the trough that was inpiding it to be pure tropical so maybe tonight it may be tropical storm ANA but they will make the call.

"Ana" is continuing to becoming more and more interesting for system in mid to late April.

That's a very interesting development to say the least. Sounds like Lawrence is passing the buck on making that call :-)

Agreed, it's signature is looking more tropical with the banding features, although the actual center is a bit left of the main convection. Quite a

Well if they say this system has become purely tropical then i expect too see them explain the water temps and how we now have a tropical system form in 70degree water when before they always said you needed atleast 79 degree water just to sustain a purely tropical system?????

Interesting to say the least.

If trend continues for more convection wrapping around center then it will be pure tropical storm ANA as the shear is not so strong right now.

Once again, Ana is experiencing a late-afternoon flair-up. If the convection weakens tonight, I still think that the NHC will change their tone about this becoming tropical. But considering this system is over 70 degree waters, this is incredible.

Well if I didn't know what the date was and how cool the water temps were then I would say Ana is a nice little TS. The convection has really increased late this afternoon and it will be interesting to see it does tonight.

Thermodynamics can support a tropical system with ssts cooler than 80 degrees.

whatever she is she is nice to watch!!! :wink:

Agree rainband nice to watch in open waters without affecting any land.

Agree Trwxwatcher. There is nothing written in stone that says a tropical system must have 80+ degree water. Ana is also tapping warmth from the atmosphere to her south. Nice little spin. Her forward acceleration has also slowed. I'm not ready to track yet though :o . Really a tease, since it may be a long wait 'til the next one. Cheers!!

Right, we generally here that we need 79/80 degree water temperatures for tropical cyclone development. The key word being "generally."

Storms like Subtropical Storm Ana are unique as we have been saying and something more may come of it, even with the direction over the short term of Subtropical Ana isn't etched in stone.

The way the system has been moving over the last 24 to 72 hours and not having as much effect by the trough are making this system even more concerning to watch.

Ana looks more tropical than subtropical IMO.
