Satellite imagery of Invest 90 shows a well defined area of showers and thunderstorms with outer banding already evident on the southern part of the system. What concerns me is the raggedness of the system, especially on the north and eastern side of the invest. This raggedness leads me to believe that conditions across those areas are unfavorable for development, and also tells me that development of this system in the next 48 hours does not seem to great unless the system is able to better organize itself.
There is no model guidance available yet, and no satellite floaters on site yet. Due to those two lacking factors, I am unable to accurately provide any other details.
