On Monday, Typhoon Bavi hammered Guam and the Northern Mariana Islands, bringing strong winds and heavy rain. The Category 5 storm caused power outages and warnings of flash flooding across these U.S. territories.

According to the National Weather Service, Bavi’s force was evident as it moved over Rota, part of the Northern Mariana Islands. No casualties or injuries were reported in the region by early Monday afternoon.

On Sunday night, as the storm loomed closer, Saipan experienced an island-wide power outage. The Commonwealth Utilities Corporation, responsible for the island’s electricity, reported this incident in the capital of the Northern Marianas.

The Guam Power Authority shared on Monday that downed power lines from powerful winds and gusts resulted in outages across Guam, with expectations of further interruptions. Forecasts predicted 12 to 16 inches of rain for much of the region through Tuesday, with Rota possibly facing up to 20 inches. The region remains under a typhoon warning and flood watch, while Rota faces an extreme wind warning.

Guam’s authorities, addressing the storm’s approach, activated the highest level of their four-tier alert system and opened evacuation shelters for residents. Accessibility was restricted to U.S. military facilities on the island.

As of Monday afternoon, both main airports in Guam and the Northern Marianas canceled all flights, and operations at several ports were suspended.

Bavi affects a region still healing from April’s Typhoon Sinlaku, which resulted in substantial damage. This situation continues to develop.
