Guam and the Northern Mariana Islands—both territories of the United States—are bracing for a punch from a strengthening typhoon in the western Pacific. The National Weather Service issued a sobering statement that “devastating damage is likely” as the typhoon passes very close to the islands on Friday.

Typhoon Dolphin isn’t a classically beautiful typhoon on satellite imagery, but what it lacks in appearances it more than makes up for in fury. The latest advisory from the National Weather Service in Guam shows that Dolphin has sustained winds of 110 MPH, and it should strengthen to category three status before it begins impacting the islands.
