Tropical Storm Khanun Spins East of the Philippines

Tropical Khanun was spinning east of the Philippines on Friday. At 5:00 p.m. EDT on Friday the center of Tropical Storm Khanun was located at latitude 16.0°N and longitude 134.4°E which put it about 870 miles (1405 km) south-southeast of Okinawa. Khanun was moving toward the northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 996 mb.

Tropical Storm Khanun gradually became more organized as it spun east of the Philippines on Friday. The distribution of thunderstorms in Khanun’s circulation was asymmetrical. Many of the thunderstorms were occurring in bands in the southern half of Tropical Storm Khanun. The strongest winds were occurring in those rainbands. Winds to tropical storm force extended out 200 miles (320 km) in the southern side of Khanun. Bands in the northern half of Khanun consisted primarily of showers and lower clouds. The winds in the northern side of Tropical Storm Khanun were blowing at less than tropical storm force. Storms near the center of Khanun’s circulation generated upper level divergence that pumped mass away to the south of the tropical storm.

Tropical Storm Khanun will move through an environment that will be somewhat favorable for intensification during the next 24 hours. Khanun will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the eastern side of an upper level ridge over eastern China. The ridge will produce northerly winds that will blow toward the top of Khanun’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Storm Khanun is likely to intensify gradually during the next 24 hours.

Tropical Storm Khanun will move around the southwestern side of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Khanun toward the northwest during the next 24 hours. On its anticipated track, Tropical Storm Khanun will move toward the Ryukyu Islands. Khanun could approach Okinawa in less than 72 hours.

Elsewhere, Tropical Storm Doksuri weakened as it moved farther inland over eastern China. Doksuri was still dropping heavy rain over parts of eastern China. At 2:00 p.m. EDT on Thursday the center of Tropical Storm Doksuri was located at latitude 28.9°N and longitude 117.0°E which put it about 25 miles (40 km) south of Jingdezhen, China. Doksuri was moving toward the north-northwest at 18 m.p.h. (30 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 996 mb.

Tropical Storm Doksuri Intensifies East of the Philippines

Tropical Storm Doksuri intensified east of the Philippines on Saturday. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Doksuri was located at latitude 14.9°N and longitude 128.7°E which put it about 830 miles (1340 km) southeast of Taipei, Taiwan. Doksuri was moving toward the west-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 989 mb.

Tropical Storm Doksuri exhibited better organization as it intensified over the Western North Pacific Ocean east of the Philippines on Saturday. The inner end of a rainband wrapped around the eastern side of the center of Doksuri’s circulation. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical storm. More thunderstorms developed in bands in the eastern half of Tropical Storm Doksuri. Bands in the western half of Doksuri still consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 115 miles (185 km) from the center of Doksuri.

Tropical Storm Doksuri will move through an environment favorable for intensification during the next 24 hours. Doksuri will move over water where the Sea Surface Temperatures are near 30˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Doksuri will intensify during the next 24 hours. Doksuri is likely to strengthen to a typhoon on Sunday.

Tropical Storm Doksuri will move around the southwestern side of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Doksuri toward the northwest during the next 24 hours. On its anticipated track, Tropical Storm Doksuri will move closer to northern Luzon. Doksuri could reach Taiwan in less than four days.

Tropical Storm Doksuri Forms East of the Philippines

Tropical Storm Doksuri formed east of the Philippines on Thursday night. At 11:00 p.m. EDT on Thursday the center of Tropical Storm Doksuri was located at latitude 14.0°N and longitude 133.0°E which put it about 620 miles (1000 km) east of Legazpi, Philippines. Doksuri was moving toward the north-northwest at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1002 mb.

A low pressure system over the Western North Pacific Ocean east of the Philippines strengthened on Thursday night and the Japan Meteorological Agency designated the system as Tropical Storm Doksuri. The circulation around Tropical Storm Doksuri exhibited more organization on satellite images. More thunderstorms developed in bands revolving around the center of Doksuri’s circulation. Storms near the center of circulation began to generate upper level divergence that pumped mass away from the tropical storm.

Tropical Storm Doksuri will move through an environment favorable for intensification during the next 48 hours. Doksuri will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the middle of an upper level ridge east of the Philippines. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Tropical Storm Doksuri will intensify during the next 48 hours. Doksuri is likely to strengthen to a typhoon during the weekend.

Tropical Storm Doksuri will move around the southwestern side of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Doksuri slowly toward the northwest during the next 48 hours. On its anticipated track, Tropical Storm Doksuri will move closer to northern Luzon.

Typhoon Talim Nears Ryuku Islands

Typhoon Talim neared the Ryukyu Islands late on Tuesday.  At 11:00 p.m. EDT on Tuesday the center of Typhoon Talim was located at latitude 24.4°N and longitude 126.3°E which put it about 125 miles (200 km) east of Ishigaki, Japan.  Talim was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (170 km/h).  The minimum surface pressure was 967 mb.

A large circular eye formed at the center of Typhoon Talim on Tuesday.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in those storms.  Additional bands of showers and thunderstorms were revolving around the core of the circulation.  The entire circulation became much more circular and symmetrical.  The thunderstorms in the core of Talim were generating upper level divergence which was pumping mass away from the center of circulation.

Typhoon Talim will move through an environment favorable for intensification for several more days.  Talim is moving over water where the Sea Surface Temperature is near 30°C.  An upper level ridge northeast of Talim is producing easterly winds that are blowing toward the top of the circulation.  Those winds are not as strong as the were 24 hours ago and the vertical wind shear has decreased.  Typhoon Talim is likely to intensify further during the next 24 to 48 hours.

Typhoon Talim is moving near the western end of a subtropical ridge which is steering the typhoon toward the northwest.  Talim is expected to turn toward the north as it rounds the western end of the ridge.  In 24 to 48 hours Talim will begin to be affected by westerly winds from the middle latitudes.  Those winds will cause Typhoon Talim to turn toward the northeast.  On its anticipated track Typhoon Talim will move across the Ryukyu Islands on Wednesday.  It looks like the center and strongest part of Typhoon Talim will move between Ishigaki and Okinawa.  Typhoon Talim will bring strong gusty winds and locally heavy rain to the southern Ryukyu Islands.  The core of Typhoon Talim is forecast to pass west of Okinawa before it turns northeast toward the larger islands of Japan.

Elsewhere in Western North Pacific, Tropical Storm Doksuri was slowly intensifying as it moved west of the Philippines.  At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Doksuri was located at latitude 14.6°N and longitude 116.6°E which put it about 760 miles (1225 km) east-southeast of Vinh, Vietnam.  Doksuri was moving toward the west at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 995 mb.

The circulation of Tropical Storm Doksuri became more organized on Tuesday.  Numerous bands of showers and thunderstorms formed and began to revolve around the center or circulation.  Storms near the core began to generate upper level divergence.  Tropical Storm Doksuri will be moving through a favorable environment.  Doksuri will move over warm Sea Surface Temperatures and through and area where the upper level winds are not too strong.  Tropical Storm Doksuri is likely to intensify and it could eventually strengthen into a typhoon.  Tropical Storm Doksuri is forecast to continue moving  toward the west.  On its anticipated track Doksuri could be near Hainan Island in 48 hours and it could approach the coast of Vietnam in about three days.
