Due to its rapid motion, Estelle kept pace with a large swell of water that it generated. In combination with a high spring tide and peripheral winds generated by Estelle, huge waves crashed on the shores of the Big Island on the afternoon of July 22. The high waves washed away five beachfront homes and severely damaged dozens of others in Vacation Land. The total damage was around 2 million (1986 USD) dollars. On Maui, waves washed away a dirt road on the eastern part of the island between Kipahulu and Kaupo.
