Antonio B. Won Pat International Airport
Communications on the island failed due to the winds; the entire island was left without power and phone service. The winds greatly damaged 715 power poles and 513 transformers, leaving about $52 million in electrical damage reported (2002 USD, $  USD). The local weather office's communication link was cut off after flooding damaged a telecommunication facility, causing the National Weather Service in Honolulu, Hawaii, to provide backup support by temporarily issuing warnings and advisories. Many anemometers near the northern coastline failed from the winds. The winds collapsed several walls at the Guam Memorial Hospital, resulting in major damage throughout the northern two-thirds of the facility and several units being shut down. Several hotels, churches, and schools received moderate damage, and the Antonio B. Won Pat International Airport received damage to navigation equipment. Typhoon Pongsona also left 65% of the island's water wells inoperable, with most of Guam left without water service following the storm. Officials estimate the typhoon destroyed 1,300 homes, severely damaged 1,825, and lightly damaged 4,800.
