What happened
The episode as NWS GUA wrote it up.
A monsoon depression moved across the area and became Tropical Depression 15W west of Guam on the 9th. It eventually increased strength to become Tropical Storm Ewiniar on the 10th when it was well to the northwest of Guam. Strong winds and heavy rain over Guam as a result of the passage of the depression. The Guam Power Authority began receiving reports of numerous power outages across the island around midnight. The heavy rain caused a landslide along Marine Drive between Chen's Furniture and the Mobil gas station. Rocks and gravel fell from the cliff onto the roadway. The string winds also toppled a 60 foot Norfolk pine tree in Santa Rita. The tree fell on the roof of Richard Borja's house. No injuries were reported. 1.47 inches of rain fell during the day at the National Weather Service Office. Gust of 30 to 40 mph were measured across Guam.
