Typhoon Malakas Brings Winds and Rain to Iwo To

Typhoon Malakas brought strong winds and heavy rain to Iwo To on Thursday. At 5:00 p.m. EDT on Thursday the center of Typhoon Malakas was located at latitude 25.6°N and longitude 140.4°E which put it about 100 miles (160 km) west of Two To. Malakas was moving toward the north-northeast at 24 m.p.h (39 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 964 mb.

Typhoon Malakas weakened as it approached Iwo To, but Malakas still brought strong winds and heavy rain to the island. An upper level trough near Japan was producing strong southwesterly winds that were blowing toward the top of Malakas’ circulation. Those winds were causing strong vertical wind shear and the shear was affecting the distribution of thunderstorms. The strongest thunderstorms were occurring in bands in the eastern half of Typhoon Malakas. Bands in the western half of the circulation consisted primarily of showers and lower clouds.

There continued to be a large circulation around Typhoon Malakas. Winds to typhoon force extended out 60 miles (95 km) from the center of Malakas. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Malakas was 17.8. The Hurricane Size Index (HSI) was 21.1 and the Hurricane Wind Intensity Size Index (HWISI) was 38.9.

Typhoon Malakas will move through an environment unfavorable for intensification during the next 36 hours. Malakas will move over water where the Sea Surface Temperatures are near 23˚C. The upper level trough near Japan will continue to produce strong southwesterly winds that will blow toward the top of the typhoon’s circulation. Those winds will cause strong vertical wind shear. Typhoon Malakas will continue to weaken during the next 36 hours. The combination of colder water and strong vertical wind shear will cause Malakas to make a transition to a strong extratropical cyclone.

The upper level trough near Japan will steer Typhoon Malakas quickly toward the northeast during the next 36 hours. On its anticipated track Typhoon Malakas will cross the Ogasawara Islands during the next 24 hours. Malakas will bring strong winds and heavy rain the Ogasawara Islands. Heavy rain could cause flash floods in some locations. Weather conditions should improve on Iwo To on Friday when Malakas moves away from the island.

Typhoon Malakas Intensifies to Equivalent of Cat. 4 Hurricane

Typhoon Malakas intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Wednesday morning. At 11:00 a.m. EDT on Wednesday the center of Typhoon Malakas was located at latitude 19.3°N and longitude 137.5°E which put it about 475 miles (770 km) south-southwest of Two To. Malakas 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 939 mb.

Typhoon Malakas strengthened to the equivalent of a Cat. 4 hurricane on the Saffir-Simpson Scale over the Western North Pacific Ocean south-southwest of Iwo To on Wednesday morning. A circular eye with a diameter of 30 miles (50 km) was at the center of Malakas’ 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 to Typhoon Malakas. Storms near the core generated upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Malakas was large. Winds to typhoon force extended out 65 miles (105 km) from the center of Malakas. Winds to tropical storm force extended out 260 miles (415 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Malakas was 25.1. The Hurricane Size Index (HSI) was 24.0 and the Hurricane Wind Intensity Size Index (HWISI) was 49.1.

Typhoon Malakas will move into an environment unfavorable for intensification during the next 12 hours. Malakas will move over water where the Sea Surface Temperatures are near 26˚C. An upper level trough west of Japan will move toward Malakas. When the upper level trough gets closer to Typhoon Malakas, it will produce southwesterly winds that will blow toward the top of the typhoon’s circulation. Those winds will cause the vertical wind shear to increase. When the shear increases, Typhoon Malakas will start to weaken.

The upper level trough west of Japan will steer Typhoon Malakas toward the north-northeast during the next 24 hours. On its anticipated track Malakas could approach Iwo To in 30 hours. Typhoon Malakas will bring strong winds and heavy rain to Iwo To and the Ogasawara Islands. Heavy rain could cause flash floods in some locations.

The Hurricane Size Index (HSI) was 25.6 and the Hurricane Wind Intensity Size Index (HWISI) was 47.7.

Typhoon Malakas will move through an environment favorable for intensification during the next 12 hours. Malakas will move over water where the Sea Surface Temperatures are near 27˚C. It will move under the western part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce southerly winds that will blow toward the top of Malakas’ circulation. The winds at lower levels in the atmosphere will also blow from the south and there will not be much vertical wind shear. Typhoon Malakas could continue to intensify during the next 12 hours. An upper level trough west of Japan will move toward Malakas on Wednesday. When the upper level trough gets closer to Malakas, it will produce southwesterly winds that will blow toward the top of the typhoon’s circulation. Those winds will cause the vertical wind shear to increase. When the shear increases later on Wednesday Typhoon Malakas could start to weaken.

The upper level trough west of Japan will start to steer Typhoon Malakas toward the northeast at a faster speed later on Wednesday. On its anticipated track Malakas could approach Iwo To in 36 hours. Typhoon Malakas will bring strong winds and locally heavy rain to Iwo To and the Ogasawara Islands.

Former Tropical Storm Malakas intensified to a typhoon on Monday over the Western North Pacific Ocean. The inner end of a rainband wrapped around the western, southern and eastern sides of the center of Malakas. An eyewall appeared to be forming, but the rainband had not yet wrapped completely around the northern side of the center of circulation. Other bands of showers and thunderstorms were revolving around the core of Typhoon Malakas. Storms near the core generated upper level divergence that pumped mass away from the typhoon. Winds to typhoon force extended out 25 miles (40 km) from the center of Malakas. Winds to tropical storm force extended out 250 miles (400 km) from the center of circulation.

Typhoon Malakas will move through an environment favorable for intensification during the next 36 hours. Malakas will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce southerly winds that will blow toward the top of Malakas’ circulation. Those winds will cause some vertical wind shear. The wind shear will inhibit intensification, but the shear will not be large enough to prevent strengthening. Typhoon Malakas will intensify during the next 36 hours. Malakas could intensify more rapidly after an inner core with an eye and an eyewall develops. Typhoon Malakas could strengthen to a the equivalent of a major hurricane.

Typhoon Malakas will move around the western part of a high pressure system over the Western North Pacific Ocean during the next several days. The high pressure system will steer Malakas toward the north during the next 36 hours. On its anticipated track Typhoon Malakas will remain west of the Marianas during the next several days. Malakas will move toward the northeast after it moves around the western end of the high pressure system. Typhoon Malakas could approach Iwo To in three days.

Tropical Storm Malakas brought gusty winds and heavy rain to Fais on Saturday night as it passed between Guam and Yap. The circulation around Malakas strengthened on Saturday. The heaviest rain was occurring in a band that was wrapping around the southern side of the center of Tropical Storm Malakas. Other bands of showers and thunderstorms were revolving around the center of Malakas. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 130 miles (210 km) from the center of Malakas.

Tropical Storm Malakas will move through an environment mostly favorable for intensification during the next 36 hours. Malakas will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the southwestern part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce southeasterly winds that will blow toward the top of Malakas’ circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but the shear will not be large enough to prevent strengthening. Tropical Storm Malakas will intensify during the next 36 hours. Malakas could strengthen to a typhoon during the next 24 hours.

Tropical Storm Malakas will move around the western part of a high pressure system over the Western North Pacific Ocean during the next several days. The high pressure system will steer Malakas toward the northwest during the next 24 hours. On its anticipated track Tropical Storm Malakas will remain west of the Marianas during the next several days. Malakas will move more toward the north when it reaches the western end of the high pressure system. Malakas could approach Iwo To in four days.

Typhoon Nyatoh Brings Wind and Rain to Iwo To

Typhoon Nyatoh brought wind and rain to Iwo To on Friday. At 10:00 a.m. EST on Friday the center of Typhoon Nyatoh was located at latitude 24.3°N and longitude 142.9°E which put it about 80 miles (130 km) southeast of Iwo To. Nyatoh was moving toward the northeast at 24 m.p.h. (39 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 947 mb.

Bands in the northwestern side of Typhoon Nyatoh brought strong winds and heavy rain to Iwo To on Friday. The core of Nyatoh’s circulation where the strongest winds were occurring passed to the southeast of Iwo To. An upper level trough over Japan was producing strong southwesterly winds that were blowing toward the top of Typhoon Nyatoh’s circulation. Those winds caused strong vertical wind shear and the shear started to weaken Nyatoh when it approached Iwo To. A circular eye was still present at the center of Typhoon Nyatoh, but the distribution of thunderstorms was asymmetrical. The strongest thunderstorms were occurring around the eye and in bands in the northern half of Nyatoh. Bands in the southern half of the typhoon consisted primarily of showers and lower clouds.

Even though Typhoon Nyatoh was weakening, it was still the equivalent of a major hurricane. Winds to typhoon force extended out 60 miles (95 km) from the center of Nyatoh. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Nyatoh was 23.6. The Hurricane Size Index (HSI) was 22.2 and the Hurricane Wind Intensity Size Index (HWISI) was 45.8.

The upper level trough over Japan will steer Typhoon Nyatoh quickly toward the northeast during the next 24 hours. On its anticipated track Nyatoh will move away from Iwo To and the weather conditions should improve. Typhoon Nyatoh will move through an environment that will be unfavorable for a typhoon. Nyatoh will move over water where the Sea Surface Temperatures are near 24.5˚C. The upper level trough will continue to produce strong vertical wind shear. A surface high pressure system over eastern Asia will transport drier air toward the western side of Nyatoh’s circulation. Cooler water, strong vertical wind shear, and drier air will cause Typhoon Nyatoh to weaken rapidly during the next 24 hours.

Typhoon Nyatoh Strengthens to Equivalent of a Major Hurricane

Typhoon Nyatoh strengthened to the equivalent of a major hurricane over the Western North Pacific Ocean southwest of Iwo To on Thursday. At 10:00 a.m. EST on Thursday the center of Typhoon Nyatoh was located at latitude 18.7°N and longitude 137.1°E which put it about 540 miles (875 km) southwest of Iwo To. Nyatoh was moving toward the northeast at 15 m.p.h. (24 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. (230 km/h). The minimum surface pressure was 955 mb.

Typhoon Nyatoh rapidly intensified to the equivalent of a major hurricane on Thursday. A circular eye with a diameter of 35 miles (55 km) formed at the center of Nyatoh. 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 Nyatoh. Storms near the core generated strong upper level divergence that pumped mass away to the northeast of the typhoon.

The circulation around Typhoon Nyatoh increased in size on Thursday. Winds to typhoon force extended out 65 miles (105 km) from the center of Nyatoh. Winds to tropical storm force extended out 220 miles (355 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Nyatoh was 20.6. The Hurricane Size Index (HSI) was 22.1 and the Hurricane Wind Intensity Size Index (HWISI) was 42.7.

Typhoon Nyatoh will move through an environment that will become unfavorable for intensification during the next 24 hours. Nyatoh will move over water where the Sea Surface Temperatures are near 28˚C. An upper level trough near Japan will produce southwesterly winds that will blow toward the top of Nyatoh’s circulation. Those winds will cause the vertical wind shear to increase during the next 24 hours. Clockwise flow around a surface high pressure system centered over eastern Asia will transport drier air toward the northwestern part of Nyatoh’s circulation. The drier air will begin to be pulled into the northwestern part of Typhoon Nyatoh’s circulation during the next 24 hours. The combination of more vertical wind shear and drier air will cause Typhoon Nyatoh to start to weaken.

The upper level trough near Japan will steer Typhoon Nyatoh toward the northeast during the next 24 hours. On its anticipated track Typhoon Nyatoh could approach Iwo To on Friday. Although Nyatoh will weaken, it will bring strong winds and locally heavy rain to Iwo To.

Nyatoh Strengthens to a Typhoon West of the Marianas

Former Tropical Storm Nyatoh strengthened to a typhoon west of the Marianas on Wednesday. At 10:00 a.m. EST on Wednesday the center of Typhoon Nyatoh was located at latitude 15.5°N and longitude 135.6°E which put it about 580 miles (935 km) west-northwest of Guam. Nyatoh was moving toward the north-northwest at 11 m.p.h. (17 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 981 mb.

Former Tropical Storm Nyatoh continued to strengthen over the Western North Pacific Ocean west of the Marianas on Wednesday. The inner end of a rainband wrapped around the center of Typhoon Nyatoh and microwaves satellite images indicated that an eye was forming. The developing eye was surrounded by a broken 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 Nyatoh. Storms near the core generated upper level divergence that pumped mass away from the typhoon. Winds to typhoon force extended out 35 miles (55 km) from the center of Nyatoh. Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation.

Typhoon Nyatoh will move through an environment mostly favorable for intensification during the next 24 hours. Nyatoh will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western part of the axis of an upper level ridge centered near the Marianas. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Clockwise flow around a high pressure system centered over eastern Asia will transport drier air toward the northwestern part of Nyatoh’s circulation. The drier air is likely to remain northwest of Typhoon Nyatoh during the next 24 hours. Nyatoh could intensify more rapidly once the eye and eyewall become fully formed. Typhoon Nyatoh will continue to strengthen and it could intensify to the equivalent of a major hurricane during the next 24 hours. An upper level trough west of Japan will produce southwesterly winds that will begin to affect Nyatoh later this week. Those winds will create more vertical wind shear and the shear will cause Typhoon Nyatoh to weaken.

Typhoon Nyatoh will move around the western part of a high pressure system over the Western North Pacific Ocean during the next 24 hours. The high pressure system will steer Nyatoh toward the north during the next 24 hours. The upper level trough will steer Typhoon Nyatoh toward the northeast after Nyatoh moves around the western end of the high pressure system. On its anticipated track Tropical Storm Nyatoh will remain west of the Marianas during the next 24 hours. Nyatoh could approach Iwo To in 48 hours.

Typhoon Malou Brings Strong Winds, Rain to Ogasawara Islands

Typhoon Malou brought strong winds and heavy rain to the Ogasawara Islands on Thursday morning. At 5:00 a.m. EDT on Thursday the center of Typhoon Malou was located at latitude 25.6°N and longitude 141.2°E which put it about 15 miles (25 km) east of Iwo To. Malou was moving toward the north-northeast at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 100 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 967 mb.

The strong inner core of Typhoon Malou passed directly over Iwo To on Thursday morning. An eye with a diameter of 35 miles (55 km) was at the center of Malou. The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms. Winds to typhoon force extended out 70 miles (110 km) from the center of Malou. Winds to tropical storm force extended out 175 miles (280 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Malou was 16.5. The Hurricane Size Index (HSI) was 20.6 and the Hurricane Wind Intensity Size Index (HWISI) was 37.1.

An upper level trough near Japan will steer Typhoon Malou toward the northeast during the next several days. On its anticipated track Malou will move away from the Ogasawara Islands. Typhoon Malou will pass well to the southeast of the larger islands of Japan.

Typhoon Malou will move into an environment unfavorable for tropical cyclones during the next few days. Malou will move over water where the Sea Surface Temperatures are cooler. The upper level trough near Japan will produce stronger southwesterly winds that will blow toward the top of Malou’s circulation. The vertical wind shear will increase as the upper level winds get stronger. The combination of cooler water and stronger vertical wind shear will cause Typhoon Malou to weaken. The cooler water and stronger shear will also cause Malou to make a transition to an extratropical cyclone during the next few days.
