Typhoon Krathon Stalls Southwest of Taiwan

Typhoon Krathon stalled just to the southwest of Taiwan on Tuesday evening.  At 11:00 p.m. EDT on Tuesday the center of Typhoon Krathon was located at latitude 21.7°N and longitude 119.4°E which put the center about 100 miles (160 km) southwest of Kaohsiung, Taiwan.  Krathon was moving toward the east at 2 m.p.h. (3 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (235 km/h).  The minimum surface pressure was 956 mb.

Typhoon Krathon stalled just southwest of Taiwan on Tuesday.  As Krathon’s circulation remained nearly stationary, strong winds mixed cooler water to the surface of the ocean.  The cooler water reduced the energy available to be transferred to the atmosphere and Typhoon Krathon gradually weakened.

Even though Typhoon Krathon weakened on Tuesday, Krathon was still the equivalent of a major hurricane.  A circular eye with a diameter of 25 miles (40 km) was at the center of Typhoon Krathon.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolved around the core of Krathon’s circulation.  Storms near the core of Krathon generated upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Krathon was very symmetrical.  Winds to typhoon force extended out 60 miles (95 km) from the center of Krathon’s circulation.  Winds to tropical storm force extended out 160 miles (260 km) from the center of Typhoon Krathon.

The Hurricane Intensity Index (HII) for Typhoon Krathon was 20.6.  The Hurricane Size Index (HSI) was 18.6 and the Hurricane Wind Intensity Size Index (HWISI) was 39.2.  Typhoon Krathon was similar in intensity to Hurricane Rita when Rita hit Louisiana in 2005.  Krathon was not quite as big as Rita was.

Typhoon Krathon will move through an environment mostly favorable for intensification during the next 24 hours.  Krathon will be over water where the Sea Surface Temperatures are near 27°C.  It will be under the axis of an upper level ridge over eastern China.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  However, as long as the core of Typhoon Krathon remains over the cooler water it is mixing to the surface of the ocean, Krathon will continue to gradually weaken.

Typhoon Krathon will be in an area where the steering currents are weak during the next few hours.  An upper level trough over southern China will start to steer Krathon toward the slowly northeast on Wednesday.  The center of Krathon could make landfall on the coast of Taiwan northwest Kaohsiung in 24 hours.

Bands in the northeastern part of Typhoon Krathon are already dropping heavy rain on parts Taiwan.  Krathon will bring strong winds and heavier rain to the southwestern part of Taiwan when it moves closer to the coast.  Heavy rain will cause flash floods.  Typhoon Krathon could also cause a storm surge of up to 10 feet (3 meters) on the coast of southwestern Taiwan.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Jebi sped rapidly northeast of Japan.  At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Jebi was located at latitude 43.1°N and longitude 150.5°E which put the center about 300 miles (485 km) east of Kushiro, Japan.  Jebi was moving toward the northeast at 41 m.p.h. (67 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 976 mb.

Typhoon Krathon Intensifies to Equivalent of Cat. 4 Hurricane

Typhoon Krathon intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Monday as it passed just south of Taiwan.  At 5:00 p.m. EDT on Monday the center of Typhoon Krathon was located at latitude 20.7°N and longitude 119.9°E which put the center about 135 miles (220 km) south-southwest of Kaohsiung, Taiwan.  Krathon was moving toward the west at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h).  The minimum surface pressure was 927 mb.

Typhoon Krathon continued to intensify Monday.  It is now the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale.  A circular eye with a diameter of 30 miles (50 km) is present at the center of Krathon’s circulation.  The eye is surrounded by a ring of thunderstorms and the strongest winds are occurring in that ring of storms.  Numerous bands of showers and thunderstorms are revolving around the core of Typhoon Krathon.  Storms near the core generated strong upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Krathon is symmetrical.  Winds to typhoon force extend out 80 miles (130 km) from the center of Krathon’s circulation.  Winds to tropical storm force extend out 200 miles (320 km) from the center of Typhoon Krathon.

The Hurricane Intensity Index (HII) for Typhoon Krathon is 31.6.  The Hurricane Size Index (HSI) is 24.1 and the Hurricane Wind Intensity Size Index (HWISI) is 55.7.  Typhoon Krathon is similar in intensity to Hurricane Laura when Jeanne hit Louisiana in 2020.  Krathon is bigger than Laura was.

Typhoon Krathon will move through an environment favorable for intensification during the next 24 hours.  Krathon will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge south of Japan.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Even though Typhoon Krathon will be in an environment favorable for intensification, Krathon may not intensify.  Images from the Taiwan Central Weather Agency’s radar indicate that concentric eyewalls may be forming at the center of Krathon’s circulation.  If concentric eyewalls do form, then an eyewall replacement cycle would cause Typhoon Krathon to weaken during the next 24 hours.

Typhoon Krathon will move around the southwestern part of a high pressure system south of Japan.  The high pressure system will steer Krathon slowly toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Krathon will move southwest of Taiwan.  An upper level trough over southern China will start to steer Krathon toward the northeast on Wednesday.  The center of Krathon could make landfall on Taiwan near Kaohsiung.

Typhoon Krathon will be a large, powerful storm when it hits Taiwan.  Krathon will bring strong winds and heavy rain to Taiwan.  Heavy rain will cause flash floods in some locations.  Typhoon Krathon could also cause a storm surge of up to 13 feet (4 meters) on the coast of southwestern Taiwan.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Jebi strengthened south of Japan.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Jebi was located at latitude 31.7°N and longitude 141.3°E which put the center about 320 miles (520 km) south-southeast of Tokyo, Japan.  Jebi was moving toward the north at 17 m.p.h. (28 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 986 mb.

Typhoon Krathon Rapidly Intensifies to Equivalent of a Major Hurricane

Typhoon Krathon rapidly intensified to the equivalent of a major hurricane on Sunday.  At 5:00 p.m. EDT on Sunday the center of Typhoon Krathon was located at latitude 20.1°N and longitude 122.0°E which put the center about 200 miles (320 km) southeast of Kaohsiung, Taiwan.  Krathon was moving toward the west-northwest at 11 m.p.h. (17 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 950 mb.

Typhoon Krathon rapidly intensified to the equivalent of a major hurricane over the Western North Pacific Ocean south of Taiwan on Sunday.  A large circular eye with a diameter of 50 miles (80 km) was at the center of Krathon’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Typhoon Krathon.  Storms near the core of Krathon’s circulation generated upper level divergence that pumped large quatities of mass mass away from the typhoon.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The size of the circulation around Typhoon Krathon increased as it intensified.  Winds to typhoon force extended out 60 miles (95 km) from the center of Krathon’s circulation.  Winds to tropical storm force extended out 265 miles (425 km) from the center of Typhoon Krathon.

The Hurricane Intensity Index (HII) for Typhoon Krathon was 22.1.  The Hurricane Size Index (HSI) was 23.1 and the Hurricane Wind Intensity Size Index (HWISI) was 45.2.  Typhoon Krathon was similar in size and intensity to Hurricane Jeanne when Jeanne hit southeast Florida in 2004.

Typhoon Krathon will move through an environment favorable for intensification during the next 24 hours.  Krathon will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge south of Japan. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear, Typhoon Krathon will intensify during the next 24 hours.  Krathon could continue to intensify rapidly during the next few hours.  Typhoon Krathon is likely strengthen to a the equivalent of a major hurricane.

Typhoon Krathon will move around the southwestern part of a high pressure system south of Japan.  The high pressure system will steer Krathon toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Krathon will move closer to Taiwan.  The center Krathon’s circulation will approach the southern end of Taiwan in 36 hours. Typhoon Krathon is will be the equivalent of a major hurricane when it approaches Taiwan.  Bands in the northern side of Krathon’s circulation will begin to bring wind and rain to Taiwan on Monday.

Elsewhere over the Western North Pacific Ocean, the center of Tropical Storm Jebi passed just to the west of Iwo To.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Jebi was located at latitude 25.8°N and longitude 140.7°E which put the center about 50 miles (80 km) west-northwest of Iwo To.  Jebi was moving toward the north at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 993 mb.

Tropical Storm Krathon Forms Southeast of Taiwan

Tropical Storm Krathon formed over the Western North Pacific Ocean southeast of Taiwan on Saturday.  At 11:00 a.m. EDT on Saturday the center of Tropical Storm Krathon was located at latitude 18.6°N and longitude 125.1°E which put the center about 480 miles (775 km) south-southeast of Taipei, Taiwan.  Krathon was moving toward the west at 4 m.p.h. (6 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.

A low pressure system over the Western North Pacific Ocean southeast of Taiwan strengthened on Saturday and the Japan Meteorological Agency designated the system as Tropical Storm Krathon.  The circulation around Tropical Storm Krathon was organizing quickly on Saturday.  The inner end of a rainband wrapped around the eastern and northern sides of the center of Krathon’s circulation.  Other bands of showers and thunderstorms were revolving around the center of Tropical Storm Krathon.  Storms near the center of Krathon’s circulation generated upper level divergence that pumped mas away from the tropical storm.

The circulation around Tropical Storm Krathon was increasing size as Krathon strengthened.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Krathon’s circulation.

Tropical Storm Krathon will move through an environment favorable for intensification.  Krathon will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge south of Japan.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear,  Tropical Storm Krathon will intensify during the next 24 hours.  Krathon could strengthen to a typhoon on Sunday.

Tropical Storm Krathon will move around the southwestern part of a high pressure system south of Japan.  The high pressure system will steer Krathon toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Krathon will move closer to Taiwan.

Elsewhere over the Western North Pacific Ocean, Tropical Depression Jebi was moving closer to Iwo To.  At 11:00 a.m. EDT on Saturday the center of Tropical Storm Jebi was located at latitude 21.7°N and longitude 142.3°E which put the center about 275 miles (445 km) south-southeast of Iwo To.  Jebi was moving toward the north-northwest 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 1000 mb.

Tropical Storm Jebi Forms West of the Northern Marianas

Tropical Storm Jebi formed west of the Northern Marianas on Friday.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Jebi was located at latitude 18.7°N and longitude 144.6°E which put the center about 60 miles (95 km) west-northwest of Agrihan. Jebi was moving toward the north-northwest at 4 m.p.h. (6 km/h).  The maximum sustained wind speed was 45 m.p.h. (65 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 1001 mb.

A low pressure system west of the Northern Marianas strengthened on Friday and the Japan Meteorological Agency designated the system as Tropical Storm Jebi.  The circulation around Tropical Storm Jebi was poorly organized.  Thunderstorms were occurring in the southeastern quadrant of Jebi’s circulation.  There were no thunderstorms near the center of Tropical Storm Jebi.  Bands in the other parts of Jebi’s circulation consisted primarily of showers and lower clouds.

Tropical Storm Jebi will move through an environment somewhat favorable for intensification during the next 24 hours.  Jebi will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southeastern part of an upper level ridge south of Japan.  The upper level ridge will produce northeasterly winds that will blow toward the top of Jebi’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification.  Tropical Storm Jebi could intensify a little during the next 24 hours, if the wind shear does not get any stronger.

Tropical Storm Jebi will move around the western side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Jebi toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Jebi will move slowly away from the Northern Marianas.  Jebi could approach Iwo To in 36 hours.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 20W formed south-southeast of Taiwan.  At 11:00 a.m. EDT on Friday the center of Tropical Depression 20W was located at latitude 19.6°N and longitude 125.8°E which put the center about 430 miles (690 km) south-southeast of Taipei, Taiwan.  The tropical depression was moving toward the southwest at 7 m.p.h. (11 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 1001 mb.

Typhoon Jebi Brings Wind and Rain to Japan

Typhoon Jebi brought wind and rain to Japan on Monday night.  At 11:00 p.m. EDT on Monday the center of Typhoon Jebi was located at latitude 33.9°N and longitude 134.4°E which put it about 15 miles (25 km) southwest of Tokushima.  Jebi was moving toward the north-northeast at 25 m.p.h. (40 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 945 mb.

Typhoon Jebi made landfall over eastern Shikoku on Monday night.  Jebi brought strong winds and dropped heavy rain over Shikoku and Honshu.  It retained about two thirds of an eyewall and the strongest winds were occurring in that partial eyewall.  There was a gap in the eyewall west of the center of circulation.  Several bands of showers and thunderstorms were revolving around the core of Typhoon Jebi.  Winds to typhoon force extended out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extended out about 200 miles from the center.

An upper level trough northwest of Japan will steer Typhoon Jebi quickly toward the north-northeast.  On its anticipated track Typhoon Jebi will move quickly across eastern Shikoku.  The center of  Jebi will make landfall on Honshu near Kobe and it will move quickly toward the Sea of Japan.  Typhoon Jebi will drop heavy rain over Kobe, Osaka and Kyoto.  Heavy rain could cause flash floods in some parts of Shikoku and Honshu.  Jebi will weaken when it moves over the cooler water in the Sea of Japan.

Typhoon Jebi Moves Closer to Japan

Typhoon Jebi moved closer to Japan on Sunday.  At 11:00 p.m. EDT on Sunday the center of Typhoon Jebi was located at latitude 26.7°N and longitude 133.0°E which put it about 620 miles (1000 km) south of Kyoto, Japan.  Jebi was moving toward the northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (235 km/h).  The minimum surface pressure was 940 mb.

The circulation of Typhoon Jebi remained very well organized.  There was a circular eye at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Typhoon Jebi.  Storms around the core were generating upper level divergence which was pumping mass away toward the northeast of the typhoon.

Winds to typhoon force extended out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extended out about 230 miles (370 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Jebi was 20.6.  The Hurricane Size Index (HSI) was 24.4 and the Hurricane Wind Intensity Size Index (HWISI) was 45.0.

Typhoon Jebi will move into an environment that will become less favorable for strong typhoons.  Jebi will move over water where the Sea Surface Temperature is near 28°C.  So, there will be enough energy in the upper ocean to maintain the circulation.  However, an upper level trough northwest of Japan will produce southwesterly winds which will blow toward the top of the circulation.  Those winds will produce increasing vertical wind shear.  They will also inhibit the upper level divergence to the south of the typhoon.  Jebi will likely continue to weaken slowly on Monday.

Typhoon Jebi will move around the western end of a ridge over the Western North Pacific Ocean.  Jebi will move toward the north when it rounds the end of the ridge.  The upper level trough northwest of Japan will steer Typhoon Jebi toward the northeast when it nears Japan.  On its anticipated track Typhoon Jebi could approach Shikoku and Honshu in a little over 24 hours.  Jebi is forecast to be a typhoon when it reaches Japan.  It will bring gusty winds and drop locally heavy rain.  The rain will create the potential for flash floods.

Typhoon Jebi Turns Toward Japan

Typhoon Jebi turned toward Japan on Saturday.  At 11:00 p.m. EDT on Saturday the center of Typhoon Jebi was located at latitude 23.1°N and longitude 135.4°E which put it about 410 miles (665 km) west-southwest of Iwo To.  Jebi was moving toward the northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 130 m.p.h. (215 km/h) and there wind gusts to 160 m.p.h. (260 km/h).  The minimum surface pressure was 939 mb.

Typhoon Jebi was nearing the completion of an eyewall replacement cycle on Saturday night.  The original inner eyewall had mostly dissipated, although a portion of the lower part of that eyewall was evident on satellite images.  A large circular eye was present at the center of Typhoon Jebi.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Multiple bands of showers and thunderstorms were revolving around the core of Typhoon Jebi.  Storms around the core were generating strong upper level divergence.  Winds to typhoon force extended out about 45 miles (75 km) from the center of circulation.  Winds to tropical storm force extended out about 175 miles (280 km) from the center.

Typhoon Jebi will move through an environment capable of supporting a typhoon during the next 48 hours.  Jebi will move over water where the Sea Surface Temperature is near 28°C.  Typhoon Jebi will move through an area where the upper level winds are relatively weak on Sunday. Jebi will move closer to an upper level trough northwest of Japan on Monday.  Stronger southwesterly winds will cause more vertical wind shear and Typhoon Jebi will start to weaken at that time.

Typhoon Jebi will move around the western end of a subtropical ridge over the Western North Pacific Ocean.  Jebi will turn more toward the north on Sunday.  The upper level trough northwest of Japan will steer Typhoon Jebi more toward the northeast on Monday.  On its anticipated track Typhoon Jebi could approach Shikoku and Honshu in about two days.  Jebi is forecast to be a typhoon when it approaches Japan.

Typhoon Jebi Strengthens to Equivalent of Cat. 5 Hurricane

Powerful Typhoon Jebi strengthened into the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale on Friday.  At 11:00 a.m. EDT on Friday the center of Typhoon Jebi was located at latitude 18.8°N and longitude 141.0°E which put it about 400 miles (645 km) south of Iwo To.  Jebi was moving toward the west-northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 175 m.p.h. (280 km/h) and there were wind gusts to 210 m.p.h. (335 km/h).  The minimum surface pressure was 907 mb.

The circulation of Typhoon Jebi was very well organized and symmetrical.  There was a circular eye at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Numerous bands of showers and thunderstorms were revolving around the core of the circulation.  Storms near the core were generating strong upper level divergence which was pumping mass away from the typhoon in all directions.

Jebi is a large and powerful typhoon.  Winds to typhoon force extended out about 65 miles (105 km) from the center of circulation.  Winds to tropical storm force extended out about 195 miles (315 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Jebi was 40.4.  The Hurricane Size Index (HSI) was 21.6 and the Hurricane Wind intensity Size Index (HWISI) was 62.0.

Typhoon Jebi may have reached its maximum intensity.  Microwave satellite imagery suggested that an inner rainband may have wrapped around the existing eye and eyewall.  If that has occurred, then an eyewall replacement cycle may have begun.  An eyewall replacement cycle will cause a typhoon to weaken when the inner eyewall, where the strongest wind are, dissipates.

Typhoon Jebi will move around the western end of a subtropical ridge over the Western North Pacific Ocean.  Jebi will gradually turn toward the north as it moves around the end of the ridge.  On its anticipated track Typhoon Jebi should pass west of Iwo To.  Jebi could be approaching Japan in three days or so.

Typhoon Jebi Hits Northern Marianas

Typhoon Jebi hit the Northern Mariana Islands on Thursday.  At 11:00 a.m. EDT on Thursday the center of Typhoon Jebi was located at latitude 17.8°N and longitude 146.2°E which put it about 35 miles (55 km) east-southeast of Pagan.  Jebi was moving toward the west at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 125 m.p.h. (205 km/h) and there were wind gusts to 155 m.p.h. (230 km/h).  The minimum surface pressure was 940 mb.  A Typhoon Warning was in effect for Agrihan, Pagan and Alamagan.

Typhoon Jebi was very well organized.  There was a small eye at the center of circulation.  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 Jebi.  Storms near the core were generating strong upper level divergence which was pumping mass away from the typhoon.

Winds to typhoon force extended out about 50 miles (80 km) from the center of circulation.  Winds to tropical storm force extended out about 185 miles (295 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Jebi was 23.6.  The Hurricane Size Index (HSI) was 19.4 and the Hurricane Wind Intensity Size Index (HWISI) was 43.0.  Those indices indicate that Typhoon Jebi was capable of causing major damage.

Typhoon Jebi will be moving through an environment favorable for intensification during the next day or so.  Jebi 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 is little vertical wind shear.  Typhoon Jebi is forecast to intensify during the next 24 hours.  If an outer rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could cause the typhoon to weaken at least temporarily.

Typhoon Jebi will move around the western end of a subtropical ridge over the Western North Pacific Ocean.  Jebi will make a gradual turn toward the north during the next few days while it moves around the end of the ridge.  On its anticipated track Typhoon Jebi will move slowly away from the Northern Marianas.  Weather conditions should slowly improve when Jebi moves away.  The center of Jebi is forecast to pass south of Iwo To.  Typhoon Jebi could approach Honshu in four or five days.
