TRACKING THE TROPICS 0433 PM EDT AUG 19, 2017

RTW: Review of the Tropics

1. Not much change with this tropical wave.  This system is lacking convection (thunderstorms) and is also struggling to develop.  Atmospheric conditions are slowly becoming some what favorable for development during next week.

2. INVEST 92L is still moving through dry air and some westerly shear.  There is another upper low to the northwest of 92L that could also interfere with development.  Wind shear ahead of 92L a this time is marginal, and dry air is present.  
18z Intensity model calls for a tropical storm or even a Cat.1 hurricane to form from this weather system.  
As for the guidance models I have been seeing a trend toward the north and northeast.  But a few still take this system toward the west-northwest and Florida.  I am not real excited with this system, but I will continue to monitor it...RTW
