At approximately 10 p.m. on Saturday, July 4, 2026, the Governor placed the island in COR 2.
In coordination with the Government of Guam, Joint Region Marianas declared Tropical Cyclone Condition of Readiness (TCCOR) 2 also at approximately 10 p.m.
Current Status
A Typhoon Warning is now in effect for Guam, Rota, Tinian, and Saipan. As of 7 p.m. ChST, the center of Super Typhoon Bavi (09W) was located near 12.6°N, 150.5°E, approximately 380 miles east of Guam. Storm motion was west at 8 mph. Storm intensity was 165 mph. Latest model guidance indicates a path near or just north of Rota; the forecast track will see adjustments over the next 48 hours. All islands will see impacts, but islands closest to the center's passage will experience significantly worse conditions.
What to Expect
Winds will increase to catastrophic levels, especially near the center of Bavi. Sustained tropical storm-force winds are expected to begin early Sunday evening. For Guam, maximum winds are forecast to be in the 50 to 70 mph range, with gusts to 85 mph. Destructive typhoon-force winds are expected early Monday morning through early Monday afternoon with the passage of Super Typhoon Bavi.
Damaging winds are expected. Poorly constructed metal roof homes may be destroyed. Some well-constructed metal roof homes will have substantial damage and could become uninhabitable. Some frame homes will sustain partial wall and roof failure, and possibly blown-out windows. Loose outdoor items will become projectiles. Many areas will experience power outages with some downed power poles. Numerous large branches of healthy trees will snap, and some trees will be uprooted, especially where the ground is saturated.
Flooding and Rainfall
A Flood Watch is in effect for Guam through late Tuesday night. Excessive rainfall is likely to produce flash flooding and potential mudslides across the Marianas over the coming days.
Coastal and Marine Conditions
A Coastal Flood Watch remains in effect for Guam. A High Surf Advisory is in effect until 4 p.m. ChST Thursday, with large breaking waves of 25 to 35 feet in the surf zone.
There will be up to 4 feet of storm surge near the center of Bavi, with possibly a couple of feet of additional runup. Surf of 8 to 12 feet tonight could build to between 25 and 35 feet near the center of Bavi as it passes Monday morning. Coastal inundation will become likely beginning late Sunday afternoon, and could approach 15 feet closer to the storm center. Numerous roads may be closed. Low-lying homes, businesses, and some critical infrastructure will be inundated. Significant shoreline erosion will occur.
A Typhoon Warning remains in effect for Marianas Coastal Waters through at least Tuesday night. Sustained winds of 150 knots with gusts to 180 knots are possible near the center, with seas up to 45 feet. Conditions are expected to be catastrophic for small craft and extremely dangerous for larger vessels. Mariners should secure vessels and remain in safe harbor.
Prepare Now
Residents and visitors are advised to take the following precautionary actions:
- Those living in flood-prone areas should take action now; clear drainage areas and unblock storm drains to minimize flooding.
- Stay up to date with the latest information.
- Clear loose debris around your yard and store any items that may become airborne with heavy winds, such as canopies, tarps, and trampolines, before inclement weather arrives.
- Have an emergency kit prepared: Store enough food and water for your household for 7–10 days. Include medication, disinfectant supplies, and pet supplies.
- If using a generator, never operate it inside a home, garage, or other enclosed area, even if doors or windows are open. Operate generators outdoors and away from doors, windows, and vents.
- Secure important documents such as birth certificates, tax papers, and insurance documents, and keep copies in a waterproof bag.
- Review your emergency plan. If you do not have a plan, learn how to create one. Have plans for your family members and pets. If you are a person with disabilities or a caregiver for an elderly person, you may need to take extra steps to plan for those additional needs.
- Get emergency alerts: Stay informed by having a weather alert radio, battery-operated radio, or hand-crank radio where you can listen to emergency news.
- Gas your vehicles and get fuel for your generators.
- Pull cash from the ATM in case of power outages.
- Don't drive through flood waters. Almost half of all flash flood deaths happen in vehicles. When in your car, look out for flooding in low-lying areas, at bridges, and at highway dips. As little as 6 inches of water may cause you to lose control of your vehicle.
- Military and Federal Coordination
U.S. Naval Hospital Guam has cancelled all outpatient services for Monday, July 6, and Tuesday, July 7. USNH Guam will remain postured to support emergency services. - Rear Adm. Josh Lasky, commander, Joint Task Force-Micronesia, and his team are actively preparing to respond rapidly should assistance be requested by appropriate authority. When and if called upon, JTF-M is postured and prepared to execute Defense Support of Civil Authorities (DSCA). Forces are aligned to integrate seamlessly with local and federal partners, ensuring timely support.
Maritime Safety
The U.S. Coast Guard urges everyone to stay out of the water as Super Typhoon Bavi approaches. Coast Guard boats and cutters have been repositioned to ride out the storm safely and will return as soon as conditions allow to assess waterways, reopen ports, and support recovery operations.
