Category 1 – 74-95 mph (64-82 knots; 119-153 km/hr). Damage is limited to foliage, signage, unanchored boats and mobile homes. There is no significant damage to buildings. The main threat to life and property may be flooding from heavy rains.

Category 2 – 96-110 mph (83-95 knots; 154-177 km/hr). Roof damage to buildings. Doors and windows damaged. Mobile homes severely damaged. Piers damaged by storm surge. Some trees blown down, more extensive limb damage. Full Article
