Storm surge is less than 4′ above normal. Barametric pressure is less than 29.53″. • Hurricane Category 1 (Winds 74 – 95 mph): Light damage to buildings. Damage to unanchored mobile homes, poorly constructed signs. Some coastal flooding with minor pier damage. Storm surge is generally 4-5′ above normal.

Flooding damages piers and small craft in unprotected moorings may break their moorings. Some trees blown down. Storm surge is generally 6-8′ above normal.
