Re: ATL: ALEX - Tropical Storm
New Bern, NC is very far from TS Alex but the waves are high there and I am sure in many places of the east coast.

A well-defined eyewall, eye, and even central dense overcast are not requirements to become a hurricane. Alex could have an exposed LLC but, as long as it's generating 65 knot winds, it would have to be considered a hurricane.
I mean that its hybrid style means sustained hurricane force winds likely won’t reach the surface and it’ll probably turn post-tropical before they do.
Dennis in 1981 and Gabrielle in 2001 (among a few other examples I can't readily recall) had as bad or worse satellite appearance and reached hurricane intensity. There's still a good pressure gradient to the southeast so given the forward speed it's not out of the question.

Well if Alex has made a run for the Ugliest Hurricane Award, then we’ll know soon because recon is almost there.

Re: ATL: ALEX - Tropical Storm
Honestly, this thing might be extratropical already, or at least close. We'll see about the core once recon gets there, but there is a line of clouds extending toward Cuba. It would be funny if it managed to become a hurricane before that transition's complete, though.

Re: ATL: ALEX - Tropical Storm
Pressure down to 984 mbar, with 55 kt SFMR in the SW quadrant and likely higher winds in the NE quad. If this is still tropical (or tropical enough), then it might be a hurricane.

We might have an extratropical storm now. ADT's calling it that, though Best Track still says it's a TS

Does the center drop support an extratropical classification, or is it good enough for one last advisory?

In that case, would it still be referred to post-dissipation as TS Alex? My assumption is that it would still only be called a TS if it doesn't reach hurricane strength before going extratropical, and would only be called "Hurricane Alex" if it becomes tropical again while maintaining hurricane-force winds.

yes, it would be still classified as Ts Alex. Only if it reached hurricane status while still a tropical or subtropical cyclone then it would be called hurricane Alex in referendum to it. I think its extatropical at this point though and will remain Ts Alex in history.

Not possible. Barry has a firm grip on that one.

Looks like an ET storm, to me. Looks like a cold front extending SW from the center, too.

I am in no way a professional. Take what I say with a grain of salt as I could be totally wrong. Please refer to the NHC, NWS, or SPC for official information.

Re: ATL: ALEX - Tropical Storm
All the questions about the extratropical factor are answered in the discussion.
The satellite presentation of Alex has evolved from a more classic
sheared tropical cyclone this morning to that of an extratropical
transitioning cyclone. There are still some fragments of convection
near the center, but most of the shower and thunderstorm activity is
well removed from the center in a band around the eastern portion of
the circulation. This change in structure is due to an approaching
mid- to upper-level trough and associated dry air that has become
entrained into the circulation. Air Force reconnaissance aircraft
observations and data from NOAA buoy 41048 indicate that Alex is
slightly stronger. Reports from a center drop from the aircraft
showed that the pressure had fallen to around 984 mb, and the buoy
reported a peak one-minute wind of 52 kt at 4 meters. Based on
these data the initial intensity has been set at 60 kt. However,
the cyclone may already be beginning to fill as the latest
reconnaissance aircraft pass through the center reported that the
pressure had risen 4 mb.
