Typhoon Surigae Moves away from the Philippines

Typhoon Surigae started to move away from the Philippines on Wednesday. At 5:00 p.m. EDT on Wednesday the center of Typhoon Surigae was located at latitude 19.6°N and longitude 124.9°E which put it about 240 miles (385 km) east-northeast of Aparri, Philippines. Surigae was moving toward the north at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 150 m.p.h. (240 km/h). The minimum surface pressure was 952 mb.

Typhoon Surigae weakened slowly on Wednesday as it started to move farther away from the Philippines. A large circular eye with a diameter of 70 miles (110 km) was present at the center of Surigae. The eye was surrounded by a ring of strong thunderstorms and the stronger winds were occurring in that ring of storms. Several bands of showers and thunderstorms were revolving around the core of Typhoon Surigae. Storms near the core generated upper level divergence that pumped mass away from the typhoon.

Typhoon Surigae still had a large circulation on Wednesday. Winds to typhoon force extended out 60 miles (95 km) from the center of Surigae. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Surigae was 22.1. The Hurricane Size Index (HSI) was 22.1 and the Hurricane Wind Intensity Size Index (HWISI) was 44.2. Surigae was still the equivalent of a major hurricane.

Typhoon Surigae will move into an environment that will become less favorable for a strong typhoon during the next several days. Surigae will move over cooler water northeast of the Philippines where the Sea Surface Temperatures is near 26°C. In addition, an upper level trough over China will move toward Typhoon Surigae. The trough will produce westerly winds which will blow toward the top of the typhoon. Those winds will cause the vertical wind shear to increase. The combination of cooler water and more wind shear will cause Typhoon Surigae to weaken during the next 48 hours.

The upper level trough will steer Typhoon Surigae toward the east-northeast during the next several days. On its anticipated track Surigae will move away from the Philippines and it will stay southeast of Taiwan and the Ryukyu Islands. Surigae could approach Iwo To by the end of the weekend.

Tropical Storm Chan-hom Forms Southwest of Iwo To

Tropical Storm Chan-hom formed southwest of Iwo To on Sunday night.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Chan-hom was located at latitude 22.8°N and longitude 139.0°E which put it about 215 miles (345 km) southwest of Iwo To.  Chan-hom was moving toward the west-northwest at 3 m.p.h. (5 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 998 mb.

More thunderstorms developed near the center of a low pressure system southwest of Iwo To on Sunday night and the Japan Meteorological Agency designated the system as Tropical Storm Chan-hom.  The circulation around Tropical Storm Chan-hom was still organizing.  Thunderstorms were forming near the center of circulation, but the distribution of storms was asymmetrical.  The strongest thunderstorms were developing in bands in the southern half of the tropical storm.  Bands in the northern half of Chan-hom consisted mainly of showers and lower clouds.  Storms near the center of circulation generated upper level divergence which pumped mass away to the west of the tropical storm.  Winds to tropical storm force extended out 100 miles (165 km) in the southeastern quadrant of Tropical Storm Chan-hom.  Winds in the other parts of Chan-hom were blowing at less than tropical storm force.

Tropical Storm Chan-hom will move through an environment favorable for intensification during the next several days.  Chan-hom will move over water where the Sea Surface Temperature is near 28°C.  It will move around the southern side of an upper level ridge.  The ridge will produce easterly winds which will blow toward the top of Tropical Storm Chan-hom.  Those winds will cause some vertical wind shear.  The shear will inhibit intensification but it will not be strong enough to prevent Chan-hom from intensifying.   Tropical Storm Chan-hom could strengthen into a typhoon within 72 hours.

Tropical Storm Chan-hom will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Chan-hom toward the northwest during the next two to three days.  On its anticipated track Tropical Storm Chan-hom could approach the northern Ryukyu Islands and southwestern Japan by the end of the week.

Typhoon Maysak Brings Wind and Rain to South Korea

Typhoon Maysak brought wind and rain to South Korea on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Typhoon Maysak was located at latitude 36.9°N and longitude 128.9°E which put it about 30 miles (50 km) north-northwest of Busan, South Korea.  Maysak was moving toward the north-northeast at 30 m.p.h. (50 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. (165 km/h).  The minimum surface pressure was 950 mb.

The center of Typhoon Maysak made landfall on the south coast of South Korea west of Busan on Wednesday.  The large circulation around Maysak brought gusty winds and heavy rain to much of the Korean Peninsula.  Winds to typhoon force extended out 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out 200 miles (320 km) from the center.  The heavy rain was falling on ground that was saturated by previous tropical cyclones and other weather systems.  The rain will likely cause widespread flash flooding.

Typhoon Maysak was being steered quickly toward the north by an upper level trough over eastern Asia.  On its anticipated track the center of Maysak will move along the east coast of the Korean Peninsula.  Typhoon Maysak will weaken and it will made a transition to an extratropical cyclone during the next 24 hours.

Elsewhere over the Western North Pacific Ocean, Typhoon Haishen strengthened south of Iwo To.  At 5:00 p.m. EDT on Wednesday the center of Typhoon Haishen was located at latitude 20.3°N and longitude 138.8°E which put it about 350 miles (560 km) south-southwest of Iwo To.  Haishen was moving toward the west-northwest at 13 m.p.h. (20 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. (165 km/h).  The minimum surface pressure was 979 mb.

Typhoon Haishen will move through an environment favorable for intensification during the next 36 to 48 hours.  Haishen will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Typhoon Haishen will continue to intensify and it is likely to strengthen into the equivalent of a major hurricane.

Typhoon Haishen will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Haishen toward the northwest during the next several days.  On its anticipated track Typhoon Haishen could approach the northern Ryukyu Islands in about 72 hours.  Haishen could eventually bring wind and rain to the same areas in Kyushu and South Korea affected by Typhoon Maysak.

Large Typhoon Maysak Churns Toward South Korea

Large, powerful Typhoon Maysak churned toward South Korea on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Typhoon Maysak was located at latitude 30.1°N and longitude 126.9°E which put it about 405 miles (655 km) south-southwest of Busan, South Korea.  Maysak was moving toward the north-northeast at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 160 m.p.h. (260 km/h).  The minimum surface pressure was 932 mb.

Typhoon Maysak neared the completion of an eyewall replacement cycle on Tuesday which resulted in an increase in the size of the circulation.  The original inner eyewall had not quite dissipated, but low level convergence was focused on the much larger outer eyewall.  Winds to typhoon force extended out 90 miles (145 km) from the center of circulation.  Winds to tropical storm force extended out 240 miles (390 km) from the center of Maysak.

Typhoon Maysak was a large, dangerous tropical cyclone.  The Hurricane Intensity Index (HII) was 25.1.  The Hurricane Size Index (HSI) was 27.5 and the Hurricane Wind Intensity Size Index (HWISI) was 52.6.  Typhoon Maysak was capable of causing widespread major damage.

Since Typhoon Maysak was near the end of an eyewall replacement cycle, it will likely weaken slowly during the next 18 hours.  Maysak will move over water where the Sea Surface Temperature is near 28°C.  An upper level trough over eastern Asia will approach Typhoon Maysak on Wednesday.  The trough will produce southwesterly winds which will blow toward the top of the circulation.  Those winds will cause more vertical wind shear and the shear will cause Typhoon Maysak to weaken more quickly.

Typhoon Maysak will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Maysak toward the north during the next 24 hours.  On its anticipated track the core of Typhoon Maysak is likely to pass west of Kyushu.  Maysak could reach South Korea in about 18 hours.  Typhoon Maysak could be the equivalent of a large, major hurricane when it gets to South Korea.  Maysak will produce very strong winds over South Korea.  It will also drop heavy rain and flash floods could occur.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Haishen strengthened south of Iwo To.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Haishen was located at latitude 20.1°N and longitude 142.8°E which put it about 340 miles (545 km) south-southeast of Iwo To.  Haishen was moving toward the west-southwest at 8 m.p.h. (13 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 1000 mb.  Tropical Storm Haishen is forecast to strengthen into a typhoon and it could move toward western Japan later this week.

Typhoon Maysak Brings Wind and Rain to the Ryukyu Islands

Typhoon Maysak brought winds and rain to the Ryukyu Islands on Monday.  At 11:00 p.m. EDT on Monday the center of Typhoon Maysak was located at latitude 27.5°N and longitude 126.5°E which put it about 110 miles (175 km) west-northwest of Kadena AFB, Okinawa.  Maysak was moving toward the north-northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 160 m.p.h. (260 km/h).  The minimum surface pressure was 932 mb.

The eye and eyewall of Typhoon Maysak passed west of Okinawa on Monday.  Rainbands on the eastern side of Maysak passed over Okinawa and some of the other southern Ryukyu Islands.  A weather station at Naha reported a sustained wind speed of 58 m.p.h. (93 km/h).  A station at Kitahari (Kumejima Airport), which was closer to the center of Typhoon Maysak reported a sustained wind speed of 89 m.p.h. (144 km/h).

Satellite and radar images suggest that concentric eyewalls may have formed at the core of Typhoon Maysak.  The inner eye had a diameter of 8 miles (13 km).  A much larger outer eye with a diameter of approximately 100 miles (160 km) surrounded the inner eye.  Bands of showers and thunderstorms were revolving around the large core of Maysak.  Storms near the core were generating upper level divergence which was pumping mass away from the typhoon.

The circulation around Typhoon Maysak was large.  Winds to typhoon force extended out 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extended out 200 miles (320 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Maysak was 25.1.  The Hurricane Size Index (HSI) was 25.5 and the Hurricane Wind Intensity Size Index (HWISI).  Maysak was capable of causing widespread major damage.

Typhoon Maysak will move through an environment capable of supporting a strong typhoon during the next 24 hours, but it has likely reached its peak intensity.  The formation of concentric eyewalls normally results in a weaker, but larger tropical cyclone.  The wind speed will decrease when the inner eyewall dissipates.  When that occurs, the maximum wind speeds will occur in the larger outer eyewall.  Since Maysak will move over water where the Sea Surface Temperature is near 29°C, it will remain a typhoon for another 24 to 36 hours.

Typhoon Maysak will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Maysak toward the north during the next 36 hours.  On its anticipated track the center of Typhoon Maysak will pass west of Kyushu.  Typhoon Maysak could reach South Korea in 36 hours

Elsewhere over the Western North Pacific Ocean, Tropical Depression 11W was passing southeast of Iwo To.  At 11:00 p.m. EDT on Monday the center of Tropical Depression 11W was located at latitude 21.7°N and longitude 144.2°E which put it about 290 miles (470 km) southeast of Iwo To.  The depression was moving toward the west-southwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1006 mb.

Typhoon Maysak Strengthens to Equivalent of Major Hurricane Near Okinawa

Typhoon Maysak strengthened to the equivalent of a major hurricane near Okinawa on Monday.  At 11:00 a.m. EDT on Monday the center of Typhoon Maysak was located at latitude 25.5°N and longitude 127.0°E which put it about 110 miles (180 km) south-southwest of Kadena AFB, Okinawa.  Maysak was moving toward the north-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 936 mb.

Typhoon Maysak strengthened to the equivalent of a major hurricane on Monday as it approached Okinawa.  A circular eye with a diameter of 30 miles (50 km) was at the center of Maysak.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Typhoon Maysak.  Storms near the core were generating upper level divergence which was pumping mass away from the typhoon.

Typhoon Maysak had a large circulation.  Winds to typhoon force extended out 70 miles (110 km) from the center of Maysak.  Winds to tropical storm force extended out 200 miles (320 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Maysak was 23.6.  The Hurricane Size Index (HSI) was 24.1 and the Hurricane Wind Intensity Size Index (HWISI) was 47.7.  Typhoon Maysak was capable of causing widespread major damage.

Typhoon Maysak will move through an environment favorable for intensification during the next 12 to 24 hours.  Maysak will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Typhoon Maysak could strengthen further and it could intensify into the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale.

Typhoon Maysak will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Maysak toward the north during the next several days.  On its anticipated track the center of Typhoon Maysak will pass west of Okinawa during the next few hours.  Maysak will bring strong winds and heavy rain to Okinawa.  Typhoon Maysak could approach South Korea in about 48 hours.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 11W formed east-southeast of Iwo To.  At 11:00 a.m. EDT on Monday the center of Tropical Depression 11W was located at latitude 25.5°N and longitude 127.0°E which put it about 315 miles (515 km) east-southeast of Iwo To.  the depression was moving toward the southwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1008 mb.

Tropical Storm Kalmaegi Strengthens East of Luzon

Tropical Storm Kalmaegi strengthened east of Luzon on Saturday night.  At 10:00 p.m. EST on Saturday the center of Tropical Storm Kalmaegi was located at latitude 15.7°N and longitude 125.2°E which put it about 300 miles (185 km) east-southeast of Aparri, Philippines.  Kalmaegi was moving toward the west-northwest at 5 m.p.h. (8 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 996 mb.

After meandering for days east of Luzon, Tropical Storm Kalmaegi began to strengthen on Saturday night.  Bands of showers and thunderstorms strengthened and wrapped around the eastern and northern sides of the center of circulation.   Storms near the center began to generate upper level divergence which pumped mass away to the northeast of the tropical storm.  Bands in the western half of the circulation still consisted primarily of showers and lower clouds.  Winds to tropical storm force extended out 120 miles (195 km) from the center.

Tropical Storm Kalmaegi will move through an environment favorable for intensification during the next 24 to 36 hours.  Kalmaegi will move over water where the Sea Surface Temperature is near 29°C.  It will move south of an upper level ridge over the Western North Pacific Ocean.  The ridge will produce easterly winds which will cause some vertical wind shear.  The shear will slow the rate of intensification, but it will not be strong enough to prevent intensification.  Tropical Storm Kalmaegi could strengthen into a typhoon during the next 36 hours.

The ridge over the Western Pacific Ocean will steer Tropical Storm Kalmaegi toward the northwest during the next 36 hours.  On its anticipated track Tropical Storm Kalmaegi could approach northern Luzon in about 36 hours.  Kalmaegi could be a typhoon by that time.

Elsewhere over the Western North Pacific Ocean, Typhoon Fengshen was speeding away from Iwo To.  At 10:00 p.m. EST on Saturday the center of Typhoon Fengshen was located at latitude 26.4°N and longitude 153.1°E which put it about 690 miles (1110 km) east-northeast of Iwo To.  Fengshen was moving toward the east at 31 m.p.h. (50 km/h).  The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 962 mb.

Typhoon Fengshen Strengthens into Equivalent of a Major Hurricane

Typhoon Fengshen strengthened into the equivalent of a major hurricane on Friday.  At 4:00 p.m. EST on Friday the center of Typhoon Fengshen was located at latitude 23.0°N and longitude 142.9°E which put it about 175 miles (285 km) south-southeast of Io To.  Fengshen was moving toward the north at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 949 mb.

Typhoon Fengshen strengthened quickly into the equivalent of a major hurricane on Friday.  An eye with a diameter of 25 miles (40 km) developed at the center of Fengshen.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Typhoon Fengshen.  Storms near the core were generating strong upper level divergence which was pumping mass away to the northeast of the typhoon.

The circulation around Typhoon Fengshen increased in size on Friday.  Winds to typhoon force extended out 40 miles (65 km) from the center of circulation.  Winds to tropical storm force extended out 140 miles (225) km from the center.  The Hurricane Intensity Index (HII) for Typhoon Fengshen was 23.6.  The Hurricane Size Index (HSI) was 11.2 and the Hurricane Wind Intensity Size Index (HWISI) was 34.8.

Typhoon Fengshen may have reached its peak intensity.  Fengshen will move over water where the Sea Surface Temperature is near 28°C.  So, there will be suffiicient energy in the upper levels of the Western Pacific to support intensification.  However, a large upper level trough southwest of Japan will move toward Fengshen.  The trough will produce strong southwesterly winds which will blow toward the top of the typhoon.  Those winds will cause moderate to strong vertical wind shear and the shear will cause Typhoon Fengshen to being to weaken.

A ridge of high pressure east of Typhoon Fengshen and the upper level trough southwest of Japan will interact to steer the typhoon toward the northeast during the weekend.  On its anticipated track the core of Typhoon Fengshen which contains the strongest winds will pass southeast of Iwo To.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Kalmaegi moved very slowly toward northern Luzon.  At 4:00 p.m. EST on Friday the center of Tropical Storm Kalmaegi was located at latitude 16.0°N and longitude 125.9°E which put it about 345 miles (555 km) southeast of Aparri, Philippines.  Kalmaegi was moving toward the west at 2 m.p.h. (3 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.

Typhoon Fengshen Brings Wind and Rain to Northern Marianas

Typhoon Fengshen brought wind and rain to the Northern Marianas on Thursday.  At 10:00 p.m. EST on Thursday the center of Typhoon Fengshen was located at latitude 19.6°N and longitude 143.3°E which put it about 385 miles (620 km) south-southeast of Iwo To.  Fengshen was moving toward the northwest at 18 m.p.h. (30 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. (165 km/h).  The minimum surface pressure was 974 mb.

Typhoon Fengshen intensified rapidly into a typhoon on Thursday as it moved over the Northern Marianas.  Fengshen brought strong, gusty winds and heavy rain to Alamagan, Agrihan and Pagan.  There was a small circular eye at the center of Typhoon Fengshen.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Fengshen.  Storms near the core were generating upper level divergence which was pumping mass away from the typhoon.  Winds to typhoon force extended out 30 miles from the center of circulation.  Winds to tropical storm force extended out 85 miles (135 km) from the center.

Typhoon Fengshen will move through an environment favorable for intensification during the next day or so.  Fengshen will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Typhoon Fengshen could strengthen into the equivalent of a major hurricane on Friday.

Typhoon Fengshen will move around the western end of a ridge of high pressure over the Western North Pacific Ocean.  The ridge will steer Fengshen toward the north during the next 24 hours.  The typhoon will move toward the northeast on Saturday after it moves around the end of the ridge.  On its anticipated track Typhoon Fengshen will be south of Iwo To in about 24 hours.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Kalmaegi move closer to northern Luzon.  At 10:00 p.m. EST on Thursday the center of Tropical Storm Kalmaegi was located at latitude 16.6°N and longitude 125.0°E which put it about 250 miles (400 km) southeast of Aparri, Philippines.  Kalmaegi was moving toward the west-northwest at 12 m.p.h. (19 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.

Halong Strengthens into a Typhoon East of the Northern Marianas

Former Tropical Storm Halong strengthened into a typhoon east of the Northern Marianas on Sunday.  At 4:00 p.m. EDT on Sunday the center of Typhoon Halong was located at latitude 17.0°N and longitude 153.3°E which put it about 520 miles (840 km) east-northeast of Saipan.  Halong was moving toward the northwest at 12 m.p.h. (19 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 979 mb.

The circulation around former Tropical Storm Halong exhibited much better organization on Sunday.  An eye with a diameter of approximately 12 miles (19 km) formed at the center of Halong.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Typhoon Halong.  The strongest rainbands were north and east of the center of circulation.  Bands in the western half of Halong consisted primarily of showers and lower clouds.  Typhoon Halong may have been pulling sinking, drier air into the western half of the circulation, which may be why the bands were weaker in that part of the typhoon.  Storms around the core of Halong were generating strong upper level divergence which was pumping mass away from the typhoon.  Winds to typhoon force extended out 10 miles (15 km) from the center of circulation.  Winds to tropical storm force extended out 175 miles (280 km) from the center.

Typhoon Halong will move through an environment favorable for intensification during the next 36 to 48 hours.  Halong will move over water where the Sea Surface Temperature is near 29°C.  It will move under the western part of an upper level ridge where the winds are weak.  So, there will not be a lot of vertical wind shear.  Typhoon Halong will continue to intensify and it could strengthen into the equivalent of a major hurricane.

Typhoon Halong will move around the western end of a ridge of high pressure over the Western North Pacific Ocean.  The ridge will steer Halong toward the northwest during the next 24 hours.  After that time Typhoon Halong will move more toward the north while it moves around the western end of the ridge.  Halong will move northeastward after it moves around the end of the ridge.  On its anticipated track Typhoon Halong is forecast to remain northeast of the Northern Marianas.  Halong is expected to pass between Iwo To and Wake Island later next week.
