Personally, I think if it meets the requirements, it should be designated for consistency. What ends up happening is that a storm isn't designated even though it is like a TC, and then it falls apart when NHC waits too long. 93L has looked better than several other tropical depressions over the past day, and models have done a not-so-great job this year so far.

That being said, I'll defer to the experts on this - maybe they're seeing something we don't. 2020 might end up getting snubbed out of its record 6th July TC... I hope it doesn't try to beat 2005 in another way out of spite. :lol:


I definitely agree with you. This seems to our eyes to meet the definition of a tropical cyclone so it should be designated, but as you said maybe the NHC sees something we don't. But I've certainly seen more questionable cases and worse-looking depressions get designated before, so who knows? I think it just comes down to the fact that weather forecasting, even in real-time, is not an exact forecast and subjectivity and bias still play a part even amongst the experts.

Looks like Josephine. Guess the NHC might upgrade it in post-season if they end up missing it. On the bearish side, I'd still say this is at least a TD.

Next.

Showers and thunderstorms associated with a small area of low
pressure located a couple of hundred miles east-southeast of the
Cabo Verde Islands have become less organized since yesterday. The
system is moving northward toward less favorable environmental
conditions, and the chance of this system becoming a tropical
depression is decreasing.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.

Not sure why a storm that had a pretty defined circulation, 30-35kt winds on ASCAT, and pretty decent convection the last few days was never designated as a tropical cyclone. I guess location does really matter... if this had been in the Gulf, I think it would have definitely gained some more recognition.

At least the name Josephine will maybe have a chance of going to a better storm. Josephine hasn't been a hurricane since 1990, and it was never a major during the times it was a hurricane. I always find it quite odd that the 'I' names always cause a ruckus, but 'J' never has the same reputation even though it also happens during peak season (and it's right next to 'I'). The 'J' name has only been retired 5 times, compared to 11 times for the 'I' name (and it could even be 12 or 13 depending if Imelda and Isaias are also on the cutting block).

Poor little 93L. My unofficial take is that this has been a TD for at least the last couple days but it got ignored because of big brother Isaias. It's still firing some decent convection to its west, and if that can migrate over the centre then maybe we'll see it classified, but its chances are dwindling as we speak.

Haven't seen a recent ASCAT but if it has TD or TS winds I still think this is classifiable. We have seen plenty of sheared systems like this named. Center looks wrapped up tight on satellite imagery. Wouldn't be surprised if this was near TS strength.

The LLC is clearly well defined and convection has persisted west of the exposed center. This has probably been a tropical depression for some time now.

Showers and thunderstorms remain separated from the center of a
small area of low pressure located a couple of hundred miles east of
the Cabo Verde Islands. The system is moving northward toward less
favorable environmental conditions, and significant development of
this system appears unlikely.

Well it at least has some convection right over its centre. Could be now or never for classification.

Sustained deep convection now over the well-defined LLC. This is a TC and has been for some time. SSTs quickly drop off from here, though. Doubt they name it at 5, but that is its only chance now. If not then, should be added in the post-season.

Convection starting to cover the LLC now. NHC may have no choice but to classify if this continues.

I think they're desperately hoping it goes away so they don't have to write like two advisories on a brief middle of nowhere storm at the edge of satellite coverage. That said, they do that frequently so...

Fully agree it completely meets the definition though and am baffled as to why no classification

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

Special TWO issued, 50/50

Standard small increase in organization could lead to advisories wording, but I dunno how much more organization they're waiting to see lol, it's been impressive for 48 hours. It's like the storm exposed its LLC to prove it had one then started covering itself up, it wants to sneak in a 6th July TC so badly :)

They want to see an eye with -80 convection over the center!

from NHC page
NHC will initiate advisories on Tropical Depression Ten, located about 200 miles west of the coast of Africa at 8pm CVT (2100 UTC).

10 systems before August, with 4 being from tropical sources. Insane.
