Tropical Storm Chanchu formed in the western Pacific on May 8, 2006, roughly 500 miles east of the Philippines. The storm gradually built strength and size, reaching typhoon strength by May 11. It lost some strength as it crossed the Philippines, but once clear of the islands, it regained power and became a typhoon once again as it continued westward across the South China Sea.
