nvest 92L continues to "try" to organize a very very wide area together to form a very ample Storm.
until now the dense dry Saharan Airlayer on the system's N and W is hindering that this process could happen quick.
the system still moves very fast forward, on almost 20mphr, which make's Tracking forecasts tricky, because once slowing down would allow for quicker organisation and also could change tracking significantly.
the system is on it's approach of way less than 1000 miles off the Lesser Antilles.
there is a high chance to see a TD or TS over the northern Lesser Antilles mid week,
so the best tracking "guess" at this moment would be a Storm close to Puerto Rico's North OR South this Thursday/Friday.
this early ahead, before the Storm formed up, a more precise tracking is not possible to predict.
we keep watching and will see what is really out there Tuesday night/Wednesday, which then will leave us only a short window to finish any preparations.
I don't think the dense dry air will allow a strong storm to form,
but this is a very very wide area of heavy weather and could become a serious threat for floodings, so vulnerable areas in PR and DR should soon start to get prepared for such and watch closely in case something stronger than a TD/TS would form up.
