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.

An upper level ridge over the Western North Pacific strengthened on Friday and that increased the vertical wind shear affecting Tropical Storm Malakas. The increased wind shear prevented Malakas from strengthening on Friday. When the upper level ridge strengthened, the easterly winds blowing toward the top of Malakas’ circulation strengthened. Those stronger upper level winds increased the vertical wind shear and they caused the distribution of thunderstorms around Tropical Storm Malakas to become asymmetrical. The strongest thunderstorms were occurring in bands in the western half of Malakas’ circulation. Bands in the eastern half of the tropical storm consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation.

Tropical Storm Malakas will move through an environment more 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 southern part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce easterly winds that will blow toward the top of Malakas’ circulation. Those winds will cause some vertical wind shear, but the shear is forecast to decrease during the weekend. Tropical Storm Malakas will intensify during the next 36 hours. Malakas could strengthen to a typhoon during the weekend.

Tropical Storm Malakas will move around the southwestern 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. On its anticipated track Tropical Storm Malakas could pass between Guam and Yap during the weekend.

Tropical Storm Malakas was strengthening on Thursday night. Malakas exhibited more organization on satellite images. More thunderstorms were developing in all parts of the circulation around Tropical Storm Malakas. 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 140 miles (225 km) in the northern half of Malakas’ circulation. Winds to tropical storm force extended out 90 miles (145 km) in the southern half of the circulation.

Tropical Storm 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 29˚C. It will move under the southern part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce easterly winds that will blow toward the top of Malakas’ circulation. The winds will also be blowing from the east at most other levels in the troposphere. Since the winds will be blowing from the same direction at different levels, there will be little vertical wind shear. Tropical Storm Malakas will intensify during the next 36 hours. Malakas could strengthen to a typhoon within the next 48 hours.

Tropical Storm Malakas will move around the southwestern part of a high pressure system over the Western North Pacific Ocean during the next several days.
