Nope. The low pressure started down in the extreme SE Gulf/NW Caribbean. But before that it was a trof in the Caribbean. The front didn’t reach that far. It finally closed off because of thunderstorms lowering the pressure (latent heat release of condensation in the convective complex). It’s of tropical origins.
Thanks for the reply but this article seems to indicate that it did originate from a remnant cold front:
TALLAHASSEE, Fla. (WTXL) -- An area of vast moisture is becoming better organized over the southeastern Gulf of Mexico.The moisture is associated with a broad-stretching area of low pressure, originating from a leftover cold front over the northwestern Caribbean Sea from earlier this week. It has been slowly moving through the Yucatan Channel and approaching the southeastern Gulf of Mexico.
