So what exactly does this mean cycloneye? Has it strenghtened or has it at the least maintained itself?

[Sanibel]

999 should make a run at TS before shore...

[Hyperstorm]

It is still a generally tropical entity, but I'm surprised the winds are not all that strong on that strong convective burst on the NE side.

This may suggest possible subtropical characteristics as well...

[Scorpion]

LoL. 33 Kts hardly even deserves TD status, much less TS. Don't TD's start at 30 mph or something like that??

[TS Zack]

999MB pressure. That is very low for a depression.

[Hyperstorm]

999MB pressure. That is very low for a depression.

The system is embedded in an environment of relatively lower pressures. Interestingly, this also indicates a transition is trying to occur into a more mid-latitude system strengthened by mid-latitude features (baroclinic).

Still...the report clearly indicates a relatively warm-core...

<RICKY>

Not tropical storm status.As I said it is extratropical or subtropical to say the least.

[Hyperstorm]

No extratropical here, yet...Cycloneye.

Check the temperature distribution...

33 KT would reflect ~29.5/30 KT at the surface which is 35 MPH.

Keep in mind that the reconnaissance plane may not have found the strongest winds yet.
