Low pressure northeast of the Azores

#1 Postby zzh » Sat Sep 11, 2021 6:44 pm

A non-tropical area of low pressure is located over the far
northeastern Atlantic several hundred miles northeast of the
Azores. This system is forecast to move south-southeastward towards
warmer waters, which could allow the low to gradually acquire some
tropical or subtropical characteristics by the middle of next week.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

I’m pretty sure this is the low that Ida merged with.

I am by no means a professional. DO NOT look at my forecasts for official information or make decisions based on what I post.

Goal: to become a registered expert over tropical and subtropical cyclones.

Lol 2021, are you attempting an Alpha repeat?

I'm pretty sure Ida is long gone by now? I mean, its remnants dissipated a while ago

Perhaps these storms are more common than we thought, and the NHC is willing to classify them now, with the precedent of Alpha and, arguably, Grace 07 and the unclassified Portual TS in 1997.

This is probably the case - not that the NHC has grown more lax, but that the precedent for classifying high-latitude TCs near Europe is now there, thanks to Vince, Pablo, and Grace, where it wasn't in 2004. There was also possibly an Alpha-analogue in November 1983, a small cyclonic system rotating within a larger upper-level system and making landfall in Portugal between the 20th and the 22nd.

Agreed; it's not like these sorts of systems are a new thing, but with better technology, the NHC is more able to detect such systems when in past years such was less likely. Not to mention not every year sees these near-Europe weak NS spin-ups, although it is interesting to see how 2019-possible 2021 will feature such

Still frontal, -50C cloud tops present on the east side.
