Hi, this is Rob Carver, again filling in for Jeff Masters.
Invest93L is still present as of the 8am EDT Tropical Weather Outlook, but I'm extremely doubtful that it will reach even tropical depression status.
Invest93L's presentation on satellite imagery does not project the image of a strengthening storm. Convection, what there is of it, appears to be anchored over the Yucatan Straits and is not following the low-level circulation center. Also, microwave imagery indicates that the convection is weak, with relatively low rainfall rates.
It is worth noting that even if more convection forms after the circulation center moves into the Gulf of Mexico, there isn't much time for the storm to strengthen. By Tuesday evening, both the NAM and GFS 06Z model runs bring a weak front down into the Gulf, raising wind shear to the point that would dissipate Invest93L.
So, after considering the above, it's my opinion that Invest93L is not likely to intensify and will dissipate in a day or so.
Comments will take a few seconds to appear.
