Guam shortly before passing north of the island. Shortly after passing the island the storm strengthened into Tropical Storm Warren. Warren kept gathering strength and reached peak intensity of 130 mph while 300 miles east of Luzon Island. Typhoon Warren moved westward and brushed the extreme northern tip of Luzon Island in the Philippines causing $10 million in damage. Warren then made landfall near Shantou, China, 13,000 homes were destroyed and 17 people were killed in Guangdong Province. Severe Tropical Storm Agnes Following the demise of Typhoon Warren, an area of disturbed weather formed southeast of Japan, and by July 27, this area had developed a closed surface circulation. At noon the same day, the JMA upgraded it into a tropical depression. Initially resembling a monsoon depression, the storm's upper-level outflow and organization increased on June 28 in response to decreased winds aloft. On June 29, both the JTWC and JMA upgraded the system into Tropical Storm Agnes. Contrary to forecasts, Agnes accelerated northeast in response to a trough northeast of Japan. At 00:00 UTC on June 30, the JTWC estimated a peak intensity of and the JMA estimated a peak intensity of , making Agnes a severe tropical storm. Twelve hours later, the system lost all its deep convection, and the JTWC issued its last warning on it at 18:00 UTC. Despite this, the JMA continued to follow Agnes through August 4, three days after the agency declared Agnes extratropical. JMA Tropical Storm Eight This was not tracked by the JTWC. Tropical Storm Bill On August 1, the monsoon trough stretched from the Gulf of Tonkin to Japan, but four days later, abruptly re-aligned. This created favorable conditions aloft for tropical cyclone formation, and an area of convection in the Philippine Sea began to rapidly develop. On the evening of August 4, the JMA upgraded the disturbance into a tropical depression, and the next day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA). However, its development rate slowed as the system separated from the monsoon trough. Tracking northeast, the low passed just southwest of the southern tip of Okinawa at 15:00 UTC on August 6. That day, the JMA upgraded the depression into a tropical storm, though the JTWC did not do the same until 24 hours later. Shortly thereafter, both agencies indicated that Bill attained its peak velocity of , an intensity it would maintain until making
