A Category 4 cyclone swept through the island kingdom of Tonga Monday, and now residents and officials are working to assess the damage from the ravages of wind and water that continue to move through the South Pacific.

The U.S. Joint Typhoon Warning Center reported maximum sustained winds of 145 miles per hour during the storm, and a state of emergency has been declared in Tonga.

When the storm made landfall in Tonga, the torrential rains had already caused damage in Samoa and American Samoa.

Direct Relief emergency response staff are currently reaching out to local healthcare partners and authorities and will respond as needs become known.
