Within the next two days, Hurricane Opal has the potential to interact with one of the weather systems annotated on the imagery. Which one?

1. Tropical System
   
2. System 1
   
3. System 2
   
4. The ITCZ (Intertropical Convergence Zone)

Hint: To answer this question, look at the direction Opal is moving then track the movement of each of the other systems.
