mph). In the day before Chataan affected the island, it dropped torrential rainfall due to its elongated structure and slow movement. Persistent winds from the larger monsoon trough generated high surf and tides of 0.3 m (1 ft) above normal across the region. The most significant effects were from the rainfall, peaking at 954 mm (37.5 in) at the Chuuk Weather Service Office over 13 days. The highest 24-hour total was 506 mm (19.9 in) on Weno Island, of which 361 mm (14.2 in) fell in 12 hours; this was greater than the average monthly rainfall total for the station. High winds downed power lines on Chuuk, while surf destroyed seawalls and buildings along the coast. The rains causes severe flooding across the island that reached in some locations, triggering at least 30 mudslides that killed 47 people. This represented the deadliest natural disaster in the island's recorded history. The landslides reached a depth of 4.6 m (15 ft), which destroyed several homes made of tin and concrete. Many people were buried by the landslides or washed into the ocean. Saltwater flooding contaminated the groundwater and destroyed much of the island's crops. Chataan damaged roads and bridges, and high winds downed power lines, which cut communications between islands. Across Chuuk, the storm destroyed about 1,000 homes and left about 1,000 people homeless. About 100 people were injured. In nearby Pohnpei state, Chataan produced 72 km/h (45 mph) winds in Nukuoro. The winds destroyed a house and a weather station. Rainfall on the atoll reached 457 mm (18.0 in). High winds, surf, and rain also affected Sapwuafik. Rough seas killed a person on Pohnpei. Crop damage in the country totaled $3 million, and overall property damage was estimated at $100 million, mostly on Chuuk. Guam Before Chataan affected Guam, officials canceled U.S. Independence Day festivities, and residents purchased storm supplies. Although the center of the eye did not strike Guam, the eyewall affected the entire island with strong winds and heavy rainfall. The highest sustained winds were estimated at 120 km/h (75 mph), with gusts to 167 km/h (104 mph) at Andersen Air Force Base. Gusts were slightly higher at Apra Harbor, peaking at 170 km/h (106 mph), and gusts may have reached as high as 200 km/h (125 mph). Similar to its effects on Chuuk, Chataan dropped heavy rainfall on Guam, peaking at 536 mm (21.1 in) on Mount Almagosa;
