[edit] Storm 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. On June 23, satellite photos revealed a 10 mile diameter eye forming in the developing storm and winds of 75 mph (120 km/h) 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 140 mph (225 km/h) and a minimal pressure of 910 millibars. The rapid intensification occurred within a 23 hour period.[1] After making landfall in the northern Philippines on June 26, Kroyn entered the South China Sea as a Category 2 typhoon.[2] Moving at 30 km/h, the storm made landfall near Hong Kong and and weakened into a strong tropical storm. After landfall, the storm dissipated on June 28. [3]
[edit] Preparations
Officials at the Joint Typhoon Warning Center issued a tropical storm warning for the Caroline Islands as Tropical Depression 6W formed.[1] In China, officials began to issue gale warnings as the typhoon was 220 miles from making landfall. Reports of evacuations from the Philippines before the storm are unavailable.[3]
[edit] Impact
When Kroyn passed over Ulithi, an island in the Caroline Islands, it brought 5.53 inches (140 mm) of rain and 70 mph (112 km/h) 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 dollars (1993 USD) in damage. The Philippine government declared 16 provinces disaster areas after the storm.[1] [3] In China, a weather station in Hong Kong recorded winds up to 70 mph (112 km/h) and a high rainfall total of 29.1 inches (73 cm). Kroyn 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.[3]
[edit] Retirement
The name Koryn was never used again due to a change in the naming list in 1996.
