Federated States of Micronesia - Typhoon Sinlaku, April 2026
Federated States of Micronesia - Typhoon Sinlaku, April 2026
Situation overview

Typhoon Sinlaku (04W) has impacted Chuuk State in the Federated States of Micronesia, causing widespread damage across lagoon islands and outer island communities. The storm
stalled near Chuuk between 9–10 April, bringing prolonged strong winds, storm surge, heavy rainfall, and dangerous sea conditions. 

In response to the deteriorating situation, the Office of the Governor of Chuuk State declared a State of Emergency on 10 April 2026 across Chuuk State to support coordinated emergency response operations.

Typhoon Sinlaku has now moved away from Chuuk State, tracking northwest toward the Mariana Islands. According to FSM National Weather Advisory, JTWC updates, and CDEOC Situation Report #3, the system’s departure marks a significant easing of

immediate meteorological threats. All tropical storm warnings and typhoon watches for Chuuk have been lifted. 

Initial reports from the Chuuk Disaster and Emergency Operations Center indicate severe damage to homes, government buildings, schools, and infrastructure, particularly on Weno Island, the main population centre of Chuuk State. Power outages, blocked
roads, communications disruptions, and displacement have been reported, with shelters opened to accommodate affected residents.

 The Chuuk State all-clear announcement (13 April 2026), supported by CDEOC reporting, confirms improved conditions; however, residual hazardous sea states and ongoing damage assessments continue to warrant caution. In line with state directives and

Governor’s Office advisories, movement restrictions—including sea travel limitations—have been lifted, allowing for the gradual resumption of activities under safety considerations.

Notwithstanding these improvements, CDEOC reporting highlights persistent communication disruptions and access constraints across several outer islands, limiting full situational awareness. Overall, as reflected in both the Chuuk State

Administrative Directive and the FSM Presidential Emergency Declaration, the situation is transitioning from immediate response to rapid damage assessment, relief delivery, and coordinated early recovery operations.
