Even though it is currently a Cat 2 hurricane, all forecast so far are calling for it to lose strenght and only be a tropical storm by 8am Monday. That is when it will be closest to SXM. You will probably get some heavy rains and some wind. Tropical storm winds are in the 39 to 73 mph range.

By Tuesday 8am it is tracked to be over PR.

So the worst weather you would experience would probably been late Sunday night and Monday morning.
