Typhoon Pongsona was among the worst typhoons to ever strike the island of Guam. The eye of Pongsona was unusually large, almost 40 miles in diameter, and passed over the northern part of Guam with sustained winds of 144 mph. Rainfall was heaviest in the north, where the University of Guam reported over 25 inches of accumulation. Gov. Carl Gutierrez called on National Guard troops to clear roads and tend to stranded residents.
