A stout tropical wave that rolled off of Africa yesterday and has rapidly blown up convection already appears to have developed at least a partially-closed low-level circulation, is now Invest-tagged, 99L.

Invest 99L is located in the extreme eastern Atlantic, and while conditions there may not be as favorable as a fledgling cyclone could like, they are supportive enough for some continued slow development. With the broad, almost gyre-like monsoon low ahead of it we have been tracking helping clear the path, 99L could have an easier go of it for a potential long-track across the Atlantic, and we are starting a Lounge on this feature at this time.

NHC has raised its chances from 10% at the 8PM TWO last night to 30% at 2AM today, and these could be conservative.
