We are in the beginning of what is considered the peak of the Atlantic hurricane season that typically runs from the middle of August to the middle to end of October.
The above graphic shows the formation points of all tropical storms in the Atlantic basin during the last half of August from 1851 to 2009. The deep tropical Atlantic is one of the most preferred regions for development.
Satellite imagery currently shows a tropical wave over the far eastern Atlantic in the vicinity of the Cape Verde Islands. Global models show this system developing into a strong tropical cyclone over the next several days.
The figure above (click on image to improve resolution) shows the National Weather Service’s Global Forecast System (GFS) model forecast valid at 8:00 am on Wednesday August 25th. The bullseye several hundred miles east-northeast of the Leeward Islands shows the current GFS depiction of where the tropical cyclone (that the model develops out of the tropical wave currently near the Cape Verde Islands) is expected to be at that time. The European Center for Medium Range Weather Forecasts (ECMWF) model also shows a developing tropical cyclone also centered several hundred miles east-northeast of the Leeward Islands by the morning of the 25th.
The fact that we are in the peak of the hurricane season and all of the global computer models show a tropical cyclone developing out of the disturbance currently in the vicinity of the Cape Verde Islands leads one to give a high probability of this system developing. Time will tell.
