Typhoon Soulik moved toward the northern Ryukyu Islands on Sunday and Typhoon Cimaron approached the Northern Mariana Islands. At 11:00 p.m. EDT on Sunday the center of Typhoon Soulik was located at latitude 25.9°N and longitude 135.8°E which put it about 450 miles (730 km) east-southeast of Yaku Shima. Soulik was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 105 m.p.h. (170 km/h) and there were wind gusts to 125 m.p.h. (205 km/h). The minimum surface pressure was 959 mb.
The structure of Typhoon Soulik changed on Sunday. A large circular eye with a diameter or 45 miles (75 km) developed at the center of circulation. A circular ring of thunderstorms surrounded the eye. The ring was thinner on the western side of the eye and there may have been breaks in the ring. Several bands of thunderstorms were revolving around the core of Typhoon Soulik. Storms around the core were generating strong upper level divergence which was pumping mass away from the typhoon. Winds to typhoon force extended out about 45 miles (75 km) from the center of circulation. Winds to tropical storm force extended out about 195 miles (315 km) from the center.
Typhoon Soulik will move through an environment that should allow it to maintain its intensity for another day or two. Soulik will move over water where the Sea Surface Temperature is near 29°C. An upper level ridge north of Japan will produce easterly winds that will blow toward the top of the typhoon, but the winds will not cause significant vertical wind shear. Typhoon Soulik could weaken a little, but it is likely to maintain most of its strength for another 24 to 48 hours.
Typhoon Soulik will move around the western end of the ridge north of Japan. The ridge will steer Soulik toward the northwest for another 36 to 48 hours. When Soulik reaches the western end of the ridge, it will turn toward the north. On its anticipated track Typhoon Soulik could reach the northern Ryukyu Islands in about 36 hours.
At 11:00 p.m. EDT on Sunday the center of Typhoon Cimaron was located at latitude 17.3°N and longitude 148.5°E which put it about 240 miles (390 km) east-northeast of Saipan. Cimaron was moving toward the west-northwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 978 mb. A Typhoon Warning was in effect for Agrihan, Pagan, Almagan. A Tropical Storm Warning was in effect for Saipan and Tinian.
Typhoon Cimaron will move through an environment that could allow it to intensify during the next several days. Cimaron will move over water where the Sea Surface Temperature is near 28°C. Upper level divergence from Typhoon Soulik could inhibit the divergence generated by Cimaron on the northern side of the circulation. Typhoon Cimaron is likely to intensify during the next day or two,
Typhoon Cimaron will move around the western end of a subtropical ridge. The ridge will steer Cimaron toward the northwest during the next two or three days. On its anticipated track Typhoon Cimaron will move over the Northern Marianas during the next 12 to 18 hours. Cimaron could reach Iwo To within 48 hours and it could be south of Honshu in about three days.
