Confirmed Threat

On April 12, 2026, Governor Lou Leon Guerrero signed Executive Order 2026-01 declaring a state of emergency and placing Guam in Condition of Readiness 2 (COR 2) at noon ChST, automatically closing non-emergency GovGuam agencies including the University of Guam. Sinlaku intensified to a typhoon and then super typhoon while passing north of Guam, with Joint Region Marianas reaching TCCOR 1E (destructive winds occurring). UOG ultimately resumed classes on April 20, 2026.

The University of Guam plans to resume classes on Monday, April 20, 2026, following the passage of Super Typhoon Sinlaku and ongoing recovery efforts across the island. Following the announcement of COR 4 at 12 pm yesterday, University officials will be conducting a thorough assessment of campus conditions to ensure facilities are safe and ready and will be working with GPA and GWA on the restoration of power and water prior to reopening. All other on-campus activities and events are canceled or will be postponed until normal operations resume. The University encourages students and employees to continue monitoring official UOG communication channels for updates.

Context

Background

The University of Guam is the only four-year land-grant institution in the Western Pacific, serving roughly 4,000 students from its main campus in Mangilao on Guam's eastern coast. On April 12, 2026, Governor Lou Leon Guerrero signed Executive Order 2026-01 declaring a state of emergency and placing the island in COR 2 at noon ChST, which automatically triggered the closure of non-emergency GovGuam agencies including UOG. Joint Region Marianas, which oversees military preparedness for the Marianas region, escalated to TCCOR 1E as Sinlaku intensified into a Category 5 super typhoon and its eye passed north of Guam over Tinian and Saipan on April 14, 2026. UOG sequenced five public campus advisories during the storm: a preparation message, the executive-order closure, two intensification updates, and the resumption announcement. Classes resumed on Monday, April 20, 2026, eight days after the initial closure, following utility restoration coordination with the Guam Power Authority and Guam Waterworks Authority. The university also hosted CIS2026 (its conference on island sustainability) as scheduled after the storm, repositioning its theme around storm resiliency.
Analysis

Key Findings

UOG's closure was automatic, triggered by the civilian COR 2 declaration rather than an internal decision, reflecting the university's status as a GovGuam instrumentality
The eight-day closure (April 12-19, 2026) reflects Sinlaku's slow forward speed, which extended Guam's peak conditions well past a normal typhoon's 24-36 hour pass-through window
UOG's parallel sequencing of civilian COR and military TCCOR updates in its campus advisories is a distinctive Marianas-region communication pattern not seen at mainland US institutions
Outcome
Guam was placed in COR 2 at noon ChST on Sunday, April 12, 2026 and JRM raised TCCOR to 1E as the storm's peak conditions arrived. UOG remained closed through the week as the slow-moving storm extended peak conditions. The university resumed classes on Monday, April 20, 2026 following a full campus assessment and coordination with Guam Power Authority and Guam Waterworks Authority on utility restoration.
