Two people aboard the Regina Marina were treated for injuries. Celeste passed close to Johnston Atoll and was the first recorded hurricane to hit that island. Many buildings on the weather station on the island lost roof tiles, and parts of most buildings were sandblasted by the wind. Celeste brought the highest recorded sustained winds in the station's thirteen years of operation, and the lowest barometric pressure ever recorded at Johnston at the time. A total of of rain was recorded by a rain gauge; this may be an underestimate due to the gauge's funnel being partly blocked by a lump of coral. Program 437, an anti-satellite weapons system, was destroyed by the hurricane. On Johnston, no casualties were reported due to evacuations of the island's inhabitants. High waves also pounded the Puna, Kau, and South Kona Coasts of the Big Island. An exact estimate of damage is not available. At the time, Celeste was longest-lasting Pacific hurricane with a lifespan of 16.25 days; that record was tied next season by Hurricane Doreen and outrun by Hurricane Fico in 1978. It is the ninth-longest lasting Pacific hurricane, tied with Kenneth (2005) and 1973's Doreen. Hurricane Diana On August 11, a tropical storm formed. It headed to the west northwest and strengthened into a hurricane on August 12. Diana then turned to the northwest, and peaked in intensity on August 1. It then headed west, and crossed into the central Pacific as a Category 1 hurricane. Shortly after crossing the basin boundary on a path directly towards the Hawaiian Islands, Diana weakened into a tropical storm. On August 18, Diana turned to the northwest. It dissipated two days later. Diana threatened the Hawaiian Islands enough to warrant the issuance of a tropical storm warning. Although it never made landfall, Diana dumped very heavy rain on the Big Island, though without flooding; the highest total was somewhere northeast of Hilo. At Vacationland, surf swept four homes off their foundations, doing extensive damage to one of them. Another home was flooded. Debris was carried inland, and of private roads were washed away. The cost of damage to the extensively damaged house was $75,000 (1972 USD; $ USD), furnishings excluded. Hurricane Estelle A swirl of thunderstorms near Clipperton Island became a tropical depression on August 15. It moved generally northwest. The depression strengthened into a tropical storm on August 16. Estelle continued to intensify,
