Typhoon Halong, known in the Philippines as Typhoon Inday, passed just south of Guam one week after Typhoon Chataan struck the island and left heavy damage. The seventh named storm of the season, Halong developed near the same location as Chataan on July 5 near the Marshall Islands. For much of its duration, the storm moved toward the northwest, gradually intensifying. Early on July 10, Halong passed just south of Guam as a tropical storm, producing high waves and gusty winds on the island. The storm disrupted relief efforts from Chataan, causing additional power outages but little damage.
