Meteorological history
An area of low pressure formed near the Caroline Islands on June 15 and moved northward and then westward where it continued to strengthen and became Tropical Storm Koryn on June 17. Then, Koryn started to move northwestwards. On June 23, satellite photos revealed a diameter eye forming in the developing storm and winds of 75 mph were also detected, prompting forecasters to upgrade Koryn to typhoon status. The next day, Koryn rapidly intensified to become the first super typhoon of the season with winds of 150 mph and a minimal pressure of 905 millibars. The rapid intensification occurred within a 23-hour period. After peaking, the typhoon began to weaken and started making landfall in the northern Philippines. After making landfall in the northern Philippines on June 26, Koryn entered the South China Sea as a Category 2 typhoon. The typhoon maintained the intensity until it made landfall. Moving at 30 km/h, the storm made landfall near Hong Kong and weakened into a strong tropical storm until the storm dissipated on June 29.
When Koryn passed over Ulithi, an island in the Caroline Islands, it brought 5.53 inches of rain and 70 mph winds. There were no reports of fatalities or injuries and minimal roof and crop damage was the only damage. In the Philippines, the storm caused extensive landslides that left 28-51 people dead, injuring 109 others and left $14 million in damage. The Philippine government declared 16 provinces disaster areasafter the storm. In China, a weather station in Hong Kong recorded winds up to 70 mph and a high rainfall total of 29.1 inches. Koryn also brought a storm tide of 2–3 meters above normal along the coast of China. Damage in China was severe. In Guangdong, winds of at least tropical storm force and heavy rains damaged crops, destroyed or severely damaged over 378,000 homes and buildings which affected over 5.3 million people. In Macau, the storm caused extensive flooding which forced over 600 people to seek shelter. High winds also force a highway bridge to close. Total damage in China was over 1.2 billion RMB.
