Ex-Danielle looks pretty good today, like a very small, but well-defined subtropical storm (like Alpha in 2020). Interesting that phase diagrams indicate the core will shift back toward the moderate, nearly symmetric warm phase today and tomorrow before it became much colder again thereafter.
Convection is a bit light right now and quite far from the centre. Should be within range of Portuguese radar within the next few hours; it will be interesting to see what it shows. Ultimately I don't think the NHC will classify this operationally; IMO it should've been tagged as a development possibility as soon as Danielle dissipated as models have been showing a possible subtropical transition since then. It had quite a good presentation before sunset
Danielle has been presenting decently throughout the night, new burst of convection came through recently. Really a shame that nobody at the NHC has taken notice, I don't know why nobody has even tagged it. Maybe someone with contacts at IPMA or the NHC could ask?
The convection weakened a lot by afternoon as the small cyclone moved over much cooler water. It possibily was subtropical between ~06 UTC yesterday and ~12 UTC today, but I give little chance that the NHC update it in the post-season analysis.
