looks like there's a surface low developing on the southern edge of that convective flare, around 150-200 mi sse of the western tip of the southern peninsula in haiti. check it out on ghcc zoom satelite. approx 16n, 75w. very sheared environment there, so it's going to struggle. the subtropical jet max is nearby; weakening, but still going to be a lot to deal with and a great impediment to development. nhc discussion refers to the disturbance either as part of a surface trough with a 1009 mb low at 16/72... i'd say the low is really at 16/75. appears to be quasi-stationary.
very surprised no invest is up.
