What is a Tropical wave and where do they come from.
Normally a tropical wave starts off as a sand storm in the Sahara Desert. Especially in the summer months there is a significant temperature gradient between the hot desert and the cooler waters along the Gulf of Guinea Coast.  So this hot, dust and sand filled wind starts moving west and developing into a trough of low. The wave, now bow shaped, is now being transported by the African Eastern Jet which moves east west across the Atlantic. 
A new tropical wave departs western North Africa about every 2-4 days between April and November, with about 60-65 waves per year, on average.
In the Atlantic 85% of all their major hurricanes have their origins traceable to these African waves and about 60% of all tropical storm and cat 1-2 hurricanes are spawned by these waves. 
Those that make it across the Atlantic and the Caribbean without tropical development (a tropical storm or hurricane) normally cross Central America and end up in the Eastern Pacific basin where they looking for a low to stimulate in the waters warmer than 80 degrees.
