Latest VIS and IR imagery suggests INVEST 92L is now a Tropical Depression, though NHC has not yet ‘called it’.
Fig 1: Latest VIS image of INVEST 92 about 1,200 NM east of the Lesser Antilles.
The low level circulation near 11.1N / 43.5W (about 1,200NM east of the Lesser Antilles) appears ‘closed’, with significant, though weak convection noted within 25NM of the center, along the S-SE side of the center.

As the polar vortex mutated through the media, it was recognized early as naïve, mocked by comedians, dismissed as scientifically imprecise and politicized. It then becomes a trigger, that supports the doubt that is the goal of the political argument to disrupt climate-change and energy policy. This is a case when the pursuit of simple metaphors and snappy descriptions of complex events fuels the rhetoric. It is a fundamentally flawed tactic of communication and a fundamentally robust way to capture attention and fuel disruption. We must do better.
