Due presence of Sahara desert that is responsible for the formation of this hurricane and its movement towards Florida.
Explanation:
Hurricane Harvey traveled from the Africa towards the Florida because these hurricane formed at the African region due to the presence of Sahara desert. The hot and dry wind of Sahara desert meets with the cool, moist air from the south produces these hurricane which then moves from the Africa to the west side where Florida is located so that's why Hurricane Harvey traveled from Africa towards the Florida.
for the storm to start/process it needs the moist air in order for both hurricanes and thunderstorms to happen, because the rotation with the moistness creates the storms.
