As of 1:45PM EDT August 1, Invest 99L has become much more organized, and now has deep convection blowing up over a well defined low level circulation.

Conditions look to remain favorable for at least the next 24 hours for continued improvement, and it is probable that 99L will become a named storm within the next day or so, and perhaps as early as tonight.

This incipient cyclone is currently centered near 12N 48W, and traveling WNW at around 15-20 mph, however the center has apparently consolidated further north than earlier estimates, giving the look of a NW to NNW track at first glance.

As a precaution, interests in the Greater & Lesser Antilles may want to begin preparations for tropical cyclone condition by this weekend.
