Was Invest 95L anything tropical?

Did Invest 95L ever meet the criteria to make it a depression or tropical storm? I say NO – it never met the criteria and was nothing but a rain maker with some significant winds.

Tropical Cyclone:
A warm-core non-frontal synoptic-scale cyclone, originating over tropical or subtropical waters, with organized deep convection and a closed surface wind circulation about a well-defined center.

It the time of 1800 (zulu) – 95L had been a frontal boundary. At around 2100 -it detached from the front so it is now on it’s own. Under NHC criteria it requires the organized deep convection to persist for 12-24 hours. Only then if it still meets the criteria – the NHC may classifying a system as a Tropical Cyclone.

Just looking at the radar imagery at the time – it did not have a fully closed circulation. Also the convection was all SW of the “center”. Some people will argue these points and that’s fine – we all have are own feelings. But just using the NHC criteria guide lines  – 95L was just nothing but a  wet and windy storm.
