The Great Red Spot is remarkably stable, having first been spotted over 300 years ago. Several factors may be responsible for its longevity, such as the fact that it never encounters solid surfaces over which to dissipate its energy and that its motion is driven by Jupiter's internal heat. Simulations suggest that the Spot tends to absorb smaller atmospheric disturbances.
At the start of 2004, the Great Red Spot is approximately half as large as it was 100 years ago. It is not known how long the Great Red Spot will last, or whether this is a result of normal fluctuations.

I wonder what causes such a large noticable disturbance. Could it be asteroids that cause it?

I live in FL, and I'd have to say if a hurricane similar to the great red spot were coming for my hometown, I would evacuate.
It is interesting, however, I am not very interested in geophysics.
