ATL: DANNY - Post-Tropical - Discussion

[Jr0d]

A bit surprised by the blow up right along the coast, I can't help but wonder if this was helped by the daytime heating on shore.

Sure we have had 4 named systems, but the overall ACE is relatively low.

live visible. Spitting out a swirl, or that is the center.

Looks like pressure has risen a couple mb on the most recent pass as convection wanes again.

That's because ACE is an absolutely terrible metric to measure storms close to the coast or with short lifespans, and we've more or less had close-to-home formations.

Before radar observations I wonder if a storm this size would even be recognized?
They might have passed it off as afternoon thunderstorms.
Quite a lot of lightning strikes in some of the squalls and its not unknown to get a tornado with a tropical storm.

I for one am glad we have the technology to catch these brief little storms; it's unfortunate that actual accurate yearly storm counts are accurate only as far back as the modern tech letting us catch 'em but eh that's the march of science.

2017 began with a record low ACE for the first five storms so early season brief storms certainly doesn't mean that'll continue; rather, it's extremely impressive that this year like last year is allowing nearly everything to spin up.

Max wind at Hilton Head still about 15 kts. Heaviest squalls are now inland. I see a weak vortex still offshore (one of at least 2). This thing doesn't have sustained TS winds circulating around a center.

Have you checked Edisto beach?

What's the ICAO? Found it - KJZI - max wind 21 kts gusting 27 kts.

Right now, somewhere, JB is claiming victory with his 2021 entire US coastline is above average vulnerable map.

[LarryWx]

As of 4 PM: NE winds 26 gusting to 29 knots

Center not onshore yet.

saved loop

Center aiming for Hilton Head. Thunderstorms again here in SAV now with this next band. Skies are pretty dark.

[Hammy]

Surprised we got a named storm out of this, especially given the satellite appearance this morning. Really looked like it had missed it's chance to get upgraded.

Can't remember the last time we've had something track W-WNW this long from that far north of a starting point.

Center aiming for Hilton Head...

Liable to ruin some mulched gardens.

[LarryWx]

 This 2nd Danny band is a doozy here in SAV, Ga, with lots of CTG lightning (some very close hits) and heavy rains.

That's a interesting observation IRT the lengthy WNW track in the true sub tropics.
Radar returns show in nice detail the tropical structure of Danny but..... The heaviest weather is West and SW of the center. Typically you would expect it to be weighted far to the E and NE of center.

[Mouton]

IMO, if they name every storm the equal of this during the season, we have a shot at getting through the Greek Alphabet.

It has been a tropical cyclones for the past 24-30 hours and was probably a 45-50 knot Tropical storm at one point last night. It was clear to me that recon was going to find it as a tropical storm!

Speaking of which, I think there’s a good chance Danny is found to have developed on the 27th in its post-season report. There was a pretty good LLC yesterday, and convection was better organized at times. Not sure about it being a TS earlier than today, though.
