Based on the recent weather brief received from the National Weather Service, Weather Forecast Office Guam, and to provide the community additional time to prepare, Governor Lou Leon Guerrero and Rear Adm. Brett Mietus anticipate placing Guam, and the respective military bases, in Condition of Readiness (COR) 2, and Tropical Cyclone Condition of Readiness (TCCOR) 2 at 5 p.m. this afternoon, April 12, 2026.

In an interview at 7 a.m. on Sunday, National Weather Service meteorologist-in-charge Brandon Aydlett shares an update that the track now shows the storm passing directly over Rota as a Category 4 typhoon.

At COR2, the Government of Guam, with the exception of essential services, will not be operational and will remain closed until COR 4 is announced.

For TCCOR 2, JRM is finalizing closing times for remaining military services, with details released later today. Residents are strongly advised to use this time to complete final preparations and limit movement to essential activities.

Leon Guerrero made a formal request to the President for a pre-landfall Emergency Disaster Declaration to support the mobilization of critical resources to the island in response to Typhoon Sinlaku.

The request describes an “imminent catastrophe" and specifically lists Public Assistance emergency protective measures, including the need for Department of Defense strategic airlift, mass care, sheltering commodities, and generators.
