Coastal flooding in the Upper Keys was severe, with areas being inundated under several feet of seawater. Along the Miami Beach waterfront, a storm tide measuring caused extensive damage to shoreline property along Biscayne Bay. Eight people on the beach were injured, primarily due to flying glass shards. Roads were inundated, with water exceeding the first floor heights of some buildings. As a result of the waves and wind, three barges were torn out of their moorings, and later drifted downwind before severing a portion of the Rickenbacker Causeway, rendering it impassable and isolating Key Biscayne from the mainland. Along the waterfront, the waves blew into hotels and shoreline residences.
