Guam is in a State of Emergency and Condition of Readiness 3 as Typhoon Bavi continues to strengthen and move toward the Mariana Islands.
The Guam Homeland Security/Office of Civil Defense said Governor Lourdes A. Leon Guerrero signed Amended Executive Order No. 2026-04, declaring a State of Emergency for Guam effective immediately.
Guam was placed in Condition of Readiness 3 at about 3 p.m. Friday, July 3.
There are no tropical cyclone watches or warnings in effect for Guam at this time. A Flood Watch is in effect for Guam through late Tuesday night.
The National Weather Service in Tiyan said Bavi had maximum sustained winds of about 90 mph as of the 11:52 a.m. ChST Special Weather Statement. That was up from 80 mph in an earlier bulletin.
Bavi was located near 12.8 degrees north and 155.2 degrees east, moving west toward the Mariana Islands at 15 mph. Officials said the storm’s eye is showing through the cloud deck, indicating continued strengthening and organization.
GHS/OCD said Bavi remains a significant threat for all of the Mariana Islands. The National Weather Service reported model trends suggesting a more southerly shift closer to Rota and Guam. Officials said it is still too soon to rule out any island from direct impacts.
The system is expected to arrive around Sunday night into Monday morning. The National Weather Service Hydrologic Outlook said Bavi could cross the Marianas as a strong Category 4 or Category 5 typhoon, though officials said that remains a forecast possibility and not a certainty.
Guam could see 6 to 12 inches of rain, with locally higher totals possible. Showers are expected to begin Saturday and continue through at least Tuesday, with the heaviest showers beginning Sunday.
The Hydrologic Outlook said rainfall could approach 15 inches near the center of Bavi. Heavy rainfall could increase the risk of flash floods and mudslides as soils become saturated.
Excessive runoff may cause flooding of rivers, creeks, streams and other low-lying and flood-prone areas.
Seas are forecast to build to 25 to 35 feet over Marianas coastal waters during Bavi’s passage. Seas could approach 40 feet or higher near the storm’s center. Surf may exceed 20 feet as Bavi arrives.
Officials said coastal inundation could exceed 7 feet over wider reefs, and residents should prepare for the potential of significant coastal inundation.
GHS/OCD is urging residents to complete preparations immediately. Residents should review their emergency plans, prepare emergency kits with enough food and water for 7 to 10 days, secure loose outdoor items, clear drainage areas and storm drains, and protect important documents in waterproof bags.
Residents near streams or rivers should prepare to move belongings away from banks and make sure nearby storm drains are not clogged.
Officials also reminded residents that generators should never be used inside a house, garage or enclosed space, even with doors or windows open. Generators should only be operated outdoors, at least 20 feet from the home.
Residents are encouraged to check on elderly and disabled neighbors and family members, stay away from beaches and coastal areas, and have multiple ways to receive updated storm information.
GHS/OCD said it will continue to monitor Typhoon Bavi with the National Weather Service Guam and provide updates as the situation develops.
