On July 5, 2002, starting at about 8 a.m., the southern half of the eye of Typhoon Chata`an passed directly over the northern part of the island of Guam. Data collected on Guam indicate that the typhoon had sustained winds of 85 to 90 miles per hour with gusts of up to 115 mi/hr. Storm rainfall totals exceeded 21 inches over the mountainous areas in south-central Guam. During the peak of the storm, rain fell at rates of up to 6.48 inches per hour. Peak flows in many rivers in southern Guam reached record levels. In some areas, peak flows had recurrence intervals of 80 years or more; four sites had recurrence intervals that were greater than 100 years. In this fact sheet, storm rainfall totals and maximum rainfall totals for durations of 1-, 3-, 6-, and 12-hours are summarized for 12 rain gages on Guam. Peak stages and/or flows were computed at 15 USGS streamflow-gaging stations and recurrence intervals for the peaks determined.
