Tropical Storm Erika Remains A Disorganized Threat

Despite her continued presence over warn ocean waters, Tropical Storm Erika continues to remain highly disorganized due to moderate to strong wind shear in the region.  Erika, currently located at 16.5 North and 63.8 West, has fluctuated back and forth between having her center exposed but strong winds and being surrounded by high intensity but poorly organized thunderstorms.  Currently with Maximum sustained winds of 45 mph and a minimum central pressure of 1006 millibars, which is up some from this morning.  You can see on the satellite image below that the center of the storm, seen just South East of Puerto Rico, is just outside the area of heaviest convection.  By tonight, expect this to change again as the convection strengthens during the diurnal maximum.

While dry air is present in the region, it is to the North and East of Erika and she is showing good outflows into these regions as seen by the high level clouds streaming out.  This is preventing the dry air from really getting involved in her core.  The region she is moving into has plenty of moisture for Erika to work with so that does not seem like it will be a major issue for her going forward.
