Yutu's eye passed roughly 130 miles north over Tinian and Saipan as the strongest typhoon to strike US territory on record, sparing Guam a direct hit but still bringing tropical-storm-force conditions that shut the island's only four-year university down for several days."

  "context": "[Super Typhoon Yutu](https://en.wikipedia.org/wiki/Typhoon_Yutu) formed in the western Pacific in October 2018 and rapidly intensified into a Category 5 storm with sustained winds near 180 mph, becoming the strongest typhoon on record to make landfall on US territory when its eye crossed directly over Tinian and Saipan in the Commonwealth of the Northern Mariana Islands overnight on October 24-25, 2018. Guam, roughly 130 miles south of the eye's track, did not take a direct hit but still faced tropical-storm-force conditions as the massive storm's outer bands swept the island. [Governor Eddie Baza Calvo placed Guam under Condition of Readiness 2 (COR2) at noon on Wednesday, October 24, 2018](https://www.kuam.com/story/41371822/guam-placed-in-cor-2-most-schools-closed-wednesday), triggering closures across the Guam Department of Education's public schools, Catholic and charter schools, and the island's two public higher-education institutions, [the University of Guam and Guam Community College](https://www.postguam.com/news/local/schools-closed-govguam-to-close-at-noon/article_f9da3ebe-d6ae-11e8-8167-ab77a270127f.html). While UOG's Mangilao campus escaped serious damage and reopened within days, the storm's direct hit on the CNMI destroyed most of Northern Marianas College's Saipan campus, a stark illustration of how sharply typhoon outcomes can diverge between neighboring US Pacific territories depending on a storm's exact track.",
