 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, 15 ft (4.6 m) to 20 ft (6.1 m) waves crashed on the shores of the Big Island on the afternoon of July 22. Five homes were destroyed and another five sustained extreme damage. Twelve other homes received minor damage. Three beachfront divisions were destroyed. Dozens of other places in Vacation Land were also damaged. On Maui, waves washed away a dirt road on the eastern part of the island between Kipahulu and Kaupo. After Estelle passed by the islands, moisture related to the tropical cyclone caused heavy rainfall in the Ka 'u and Puna districts on the Big Island. On July 22, a wind gust of 55 mph (89 km / h) was recorded near Kalapana Sand Beach. The total damage was around $ 2 million (1986 USD). Two drownings were reported on Oahu that occurred on July 23, due to rough surf caused by Estelle.
