Typhoon Lan Rapidly Intensifies to Equivalent of a Major Hurricane

Typhoon Lan rapidly intensified to the equivalent of a major hurricane over the Western North Pacific Ocean south of Japan on Thursday. At 11:00 p.m. EDT on Thursday the center of Typhoon Lan was located at latitude 27.1°N and longitude 142.8°E which put it about 615 miles (995 km) south-southeast of Tokyo, Japan. Lan was moving toward the north at 6 m.p.h. (10 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 936 mb.

Typhoon Lan intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Thursday. A circular eye with a diameter of 28 miles (45 km) developed at the center of Lan’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 Lan. Storms near the core generated upper level divergence that pumped mass away from the typhoon in all directions. The removal of large quantities of mass caused the surface pressure to decrease rapidly.

The size of the circulation around Typhoon Lan increased when Lan intensified rapidly on Thursday. Winds to typhoon force extended out 45 miles (75 km) from the center of Lan’s circulation. Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Lan was 25.1. The Hurricane Size Index (HSI) was 14.0 and the Hurricane Wind Intensity Size (HWISI) was 39.1. Typhoon Lan was similar in size and intensity to Hurricane Harvey when Harvey hit Texas in 2017.

Typhoon Lan will move through an environment favorable for intensification during the next 24 hours. Lan will move over water where the Sea Surface Temperatures are near 28°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Typhoon Lan is likely to intensify during the next 24 hours unless the inner end of a rainband wraps around the existing eye and eyewall. If concentric eyewalls form, then an eyewall replacement cycle could cause Typhoon Lan to weaken.

Typhoon Lan will move around the western part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Lan toward the northwest during the next 24 hours. On its anticipated track, Typhoon Lan will bring strong, gusty winds and locally heavy rain to Chichi Jima during the next 24 hours. Typhoon Lan could approach Honshu in four days.

Typhoon Khanun Stalls West of Okinawa

Typhoon Khanun stalled over the Western North Pacific Ocean west of Okinawa on Thursday. At 11:00 p.m. EDT on Thursday the center of Typhoon Khanun was located at latitude 27.1°N and longitude 124.8°E which put it about 200 miles (325 km) west of Okinawa. Khanun was moving toward the northeast at 4 m.p.h. (6 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 970 mb.

Typhoon Khanun weakened while it stalled west of Okinawa. Khanun had almost completed an eyewall replacement cyclone on Thursday night. The former inner eyewalll consisted of a ring of low clouds and showers. The strongest winds were occurring in the southern part of the ring of showers. A very large, broken outer eyewall with a diameter of 150 miles (240 km) surrounded the center of Typhoon Khanun. Bands of showers and thunderstorms were revolving around the outer eyewall. Storms around the outer eyewall generated upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Khanun was large, even though Khanun was weaker. Winds to typhoon force extended out 50 miles (80 km) to the south of the center of Khanun. Winds to tropical storm force extended out 190 miles (305 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Khanun was 10.4. The Hurricane Size Index (HSI) was 14.7 and the Hurricane Wind Intensity Size Index (HWISI) was 25.1. Typhoon Khanun was capable of causing regional minor damage.

Typhoon Khanun will move through an environment that will be favorable for intensification during the next 24 hours. Khanun will move over water where the Sea Surface Temperatures are near 28˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. However, Typhoon Khanun is unlikely to intensify during the next 24 hours, because of the almost completed eyewall replacement cycle. The eyewall replacement cycle disrupted the inner core of Khanun. Typhoon Khanun is unlikely to intensify until the larger outer eyewall begins to contract closer to the center of circulation. Khanun could actually weaken a little more on Friday.

Typhoon Khanun will move around the northwestern part of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Khanun toward the east-northeast during the next 24 hours. On its anticipated track, Typhoon Khanun will move back toward the Ryukyu Islands during the next 24 hours. Typhoon Khanun will to produce strong, gusty winds and locally heavy rain in Okinawa and the other northern Ryukyu Islands. Heavy rain will cause flash floods in some locations. The center of Khanun could be just north of Okinawa in 36 hours.

Large Typhoon Khanun Churns West of Okinawa

Large Typhoon Khanun churned over the Western North Pacific Ocean west of Okinawa on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Typhoon Khanun was located at latitude 26.6°N and longitude 124.6°E which put it about 190 miles (310 km) west of Okinawa. Khanun was moving toward the west-northwest at 4 m.p.h. (6 km/h). The maximum sustained wind speed was 105 m.p.h. (1650 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 951 mb.

The inner end of a rainband wrapped around an existing eye and eyewall on Wednesday and concentric eyewalls formed in Typhoon Khanun. The inner eye had a diameter of 15 miles (25 km). The inner eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. The inner eyewall was surrounded by a large clear area called a moat. The moat was surrounded by a large outer eyewall that had a diameter of 115 miles (185 km). Bands of showers and thunderstorms were revolving around the concentric eyewalls. Storms in the concentric eyewalls generated upper level divergence that pumped mass away from the typhoon.

The size of the circulation around Typhoon Khanun increased when the concentric eyewalls formed. Winds to typhoon force extended out 115 miles (185 km) from the center of Khanun’s circulation. Winds to tropical storm force extended out 235 miles (380 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Khanun was 17.8. The Hurricane Size Index (HSI) was 37.0 and the Hurricane Wind Intensity Size Index (HWISI) was 54.8. Khanun is capable of causing extensive serious damage. Typhoon Khanun was large than Hurricane Ivan was when Ivan hit the U.S. Gulf Coast in 2004. Khanun was not quite as strong as Ivan was.

Typhoon Khanun will move through an environment that will be favorable for a strong typhoon during the next 24 hours. Khanun will move over water where the Sea Surface Temperatures are near 28˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. However, Typhoon Khanun is likely to weaken during the next 24 hours, because of the concentric eyewalls. The inner eyewall is likely to weaken and the low level convergence will occur into the large, outer eyewall. Since the strongest winds are in the inner eyewall, the wind speed will decrease when the inner eyewall weakens.

Typhoon Khanun will be in an area where the steering currents are weak during the next 24 hours. On its anticipated track, Typhoon Khanun will meander west of Okinawa during the next 24 hours. Khanun is forecast to move back toward the east-northeast later this week. The center of Typhoon Khanun could pass north of Okinawa on Friday. Khanun is forecast move across the northern Ryukyu Islands in 48 hours. Typhoon Khanun will continue to produce strong, gusty winds and locally heavy rain in Okinawa and other Ryukyu Islands. Heavy rain will cause flash floods in some locations.

Typhoon Khanun Brings Wind and Rain to Okinawa

Typhoon Khanun brought wind and rain to Okinawa on Tuesday. At 5:00 p.m. EDT on Tuesday the center of Typhoon Khanun was located at latitude 25.7°N and longitude 127.1°E which put it about 50 miles (80 km) south-southwest of Okinawa. Khanun was moving toward the west-northwest at 7 m.p.h. (11 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 941 mb.

Typhoon Khanun brought strong, gusty winds and locally heavy rain to Okinawa on Tuesday. The eye and eyewall at the center of Khanun’s circulation passed just south of Okinawa. Bands in the northern part of Typhoon Khanun moved across Okinawa. A weather station at Kadena Air Force Base reported a sustained wind speed of 74 m.p.h. (119 km/h). The weather station reported a wind gust to 87 m.p.h. (141 km/h).

An eye with a diameter of 25 miles (40 km) was at the center of Typhoon Khanun. 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 Khanun. Storms near the core generated upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Khanun was large. Winds to typhoon force extended out 65 miles (105 km) from the center of Khanun’s circulation. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Khanun was 23.6. The Hurricane Size Index (HSI) was 18.2 and the Hurricane Wind Intensity Size Index (HWISI) was 41.8. Khanun is capable of causing regional major damage. Typhoon Khanun was as strong as Hurricane Dennis was when Dennis hit Northwest Florida in 2005. Khanun was much larger than Dennis was.

Typhoon Khanun will move through an environment that will become less favorable for a strong typhoon during the next 24 hours. Khanun will move over water where the Sea Surface Temperatures are near 28˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. However, there is a region of drier air northwest of the Ryukyu Islands. Some of the drier air could get pulled into the western half of Typhoon Khanun. The drier air is likely to cause Typhoon Khanun to weaken during the next 24 hours. Khanun is likely to move slowly during the next few days. Strong winds near the surface will mix cooler water to the surface of the ocean. Typhoon Khanun will extract less energy from the ocean and it is likely to continue to weaken later this week.

Typhoon 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 west-northwest during the next 24 hours. On its anticipated track, the core of Typhoon Khanun move west of Okinawa during the next 24 hours. The steering currents are likely to weaken later this week and Typhoon Khanun could meander near the Ryukyu Islands for several days. Khanun will continue to bring strong, gusty winds and locally heavy rain to Okinawa and the other southern Ryukyu Islands. Heavy rain will cause flash floods in some locations. Typhoon Khanun will also cause a significant storms surge in the parts of islands where the winds blow water toward the coast.
