Hurricane season=1990 Pacific typhoon season Super Typhoon Mike (international designation: "9025", JTWC designation: "27W", PAGASA name Ruping) was the strongest and deadliest typhoon of the
1990 Pacific typhoon season as it crossed thePhilippines in November.Meteorological history
An area of persistent convection over the
Caroline Islands was first noted in the Significant Tropical Weather Advisory onNovember 6 . As it headed westward, its outflow rapidly improved, with banding and a more circular cloud pattern. The organization continued, and it was upgraded to Tropical Depression 27W on the 7th. Early on the 8th, the depression strengthened to Tropical Storm Mike near the island ofYap .Mike continued its westward movement and its intensification rate, and became a typhoon early on
November 9 , the 18th of the season. At this time, a weakness in the subtropical ridge, which kept the storm on its westward movement, was bring Mike northward. This did not occur, and Mike kept its persistent westward motion. OnNovember 10 , the typhoon rapidly intensified, reaching peak winds of 175 mph later that day. In a 48-hour period, the typhoon deepened 99millibars to a minimum central pressure of 885 mb.Mike retained its intensity of 175 mph winds for a day as it approached the
Philippines . Fortunately for thearchipelago , the combination of an eyewall replacement cycle and land interaction to its west weakened the super typhoon. Nevertheless, Mike still hit the eastern Philippines as a 140 mph typhoon onNovember 12 . The typhoon further weakened to an 85 mph typhoon while crossing the islands, but in theSouth China Sea , conditions favored slight strengthening.Mike reached a secondary peak of 95 mph winds on
November 14 , but land interaction withVietnam again weakened it to a minimal typhoon. The forecast break in the subtropical ridge finally occurred on the 15th, causing a northwest motion. Vertical shear increased, weakening Mike to a tropical storm on the 16th. Early the next day, the storm passed over westernHainan Island , and degraded to a tropical depression that night. After a brief passage over theGulf of Tonkin Mike hit southernChina where it dissipated onNovember 18 .Impact
While crossing the western
Caroline Islands , Mike proved to be quite destructive. Extensive damage occurred to the islands, but no deaths occurred and only one injury was reported.The Philippines didn't fare so well. The typhoon's heavy rainfall produced mudslides which, combined with the heavy wind damage, resulted in over $14 million in damage (1990 USD, $20.8 million 2005 USD). Over 748 people were reported killed, making Mike the most destructive typhoon for the Philippines since
Typhoon Ike in 1984, which killed over 1,000 people. [Philippine Atmospheric Geophysical and Astronomic Services Administration. [http://www.pagasa.dost.gov.ph/cab/dtc_12.htm Most Destructive Tropical Cyclones for Month of December (1948-2000).] Retrieved on2007-02-04 .]Typhoon Mike's damage to the infrastructure of the city and province of Cebu forced its local leaders to rethink governmental priorities. A conscious effort the rebuild after the damage was promoted, resulting into the boom of the economy of Cebu, dubbed
CEBOOM .Due to the destruction in the Philippines, the name Mike was retired and was replaced by Manny. Its PAGASA name, Ruping, was also retired.
