File:KarenNov141962TIROS.gif, the most powerful tropical cyclone to ever impact Guam.]]

Guam is an island territory of the United States, located in the Northwest Pacific Ocean, and is part of the Mariana Islands. Guam lies in the path of typhoons and it is common for the island to be threatened by tropical depressions and storms, and occasional typhoons during the wet season. The highest risk of typhoons is from August through November. They can, however, occur year-round. This is a list of typhoons that caused deaths, injuries and/or damage on Guam.

Typhoons are monitored by the United States Joint Typhoon Warning Center and due to the potential damage typhoons can cause, the tropical cyclones are concerns towards civilian and military communities on the island. Some of the typhoons that had significantly impacted Guam between 1945 and 2000 were Typhoon Karen of 1962, Pamela of 1976, Omar of 1992, and Paka of 1997.

Background

Guam is the southernmost island of the Mariana Islands and an overseas territory of the United States. Being in the Northwest Pacific Ocean, the island is often threatened by typhoons in a year-round basis. In preparations for the storms, the island may be put under Tropical Cyclone Condition of Readiness, instructing residents towards safety based on the severity of the storm.{{cite web |title=Kadena AB Typhoon Guide Vol 03 |url=https://www.kadena.af.mil/Portals/40/documents/Home%20page%20links/Typhoon%20Guide%202021%20Edition%203.pdf?ver=XmuE-v3ddyEEO_WESYWMQQ%3D%3D |website=kadena.af.mil}} The Joint Typhoon Warning Center monitors the basin, and issues warnings on significant tropical cyclones for the United States Government,{{cite web|title=Products and Services Notice|location=Pearl Harbor, Hawaii|publisher=Joint Typhoon Warning Center|url=http://www.usno.navy.mil/JTWC/products-and-services-notice|access-date=October 2, 2023|archive-date=June 9, 2017|archive-url=https://web.archive.org/web/20170609092158/http://www.usno.navy.mil/JTWC/products-and-services-notice|url-status=dead}} assigning them two-digit TC numbers (with suffix "W").{{cite report|publisher=Office of the Federal Coordinator for Meteorological Services and Supporting Research|url=http://www.ofcm.gov/publications/nhop/FCM-P12-2017.pdf|title=National Hurricane Operations Plan|date=May 2017|access-date=October 14, 2018}} These warnings use a 1-minute sustained wind speed and can be compared to the Saffir–Simpson hurricane wind scale; however, the JTWC uses their own scale for intensity classifications in this basin.{{cite web|title=Frequently Asked Questions|location=Pearl Harbor, Hawaii|publisher=Joint Typhoon Warning Center|url=http://www.usno.navy.mil/JTWC/frequently-asked-questions-1/frequently-asked-questions|access-date=October 2, 2023|archive-date=October 4, 2013|archive-url=https://web.archive.org/web/20131004091412/http://www.usno.navy.mil/JTWC/frequently-asked-questions-1/frequently-asked-questions/|url-status=dead}} The United States' Joint Typhoon Warning Center (JTWC) unofficially classifies typhoons with wind speeds of at least {{convert|130|kn|mph km/h}}—the equivalent of a strong Category 4 storm on the Saffir–Simpson scale—as super typhoons.{{cite web|url=http://www.usno.navy.mil/JTWC/frequently-asked-questions-1#labels|author=Joint Typhoon Warning Center|title=What are the description labels used with tropical cyclones by JTWC?|publisher=Joint Typhoon Warning Center – Frequently Asked Questions (FAQ)|date=2008-03-31|access-date=2008-12-22|archive-date=September 1, 2013|archive-url=https://web.archive.org/web/20130901174657/http://www.usno.navy.mil/JTWC/frequently-asked-questions-1#labels|url-status=dead}}

Tropical cyclogenesis in the West Pacific commences over the summer monsoon trough. The trough peaks on October, before being dominated by winter trade winds by December. Guam is located east of the primary area for development.
