Doksuri Rapidly Intensifies to a Typhoon

Former Tropical Storm Doksuri rapidly intensified to a typhoon over the Western North Pacific Ocean east of Luzon on Sunday. At 11:00 a.m. EDT on Sunday the center of Typhoon Doksuri was located at latitude 15.2°N and longitude 127.4°E which put it about 475 miles (765 km) southeast of Aparri, Philippines. Doksuri was moving toward the west-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h). The minimum surface pressure was 972 mb.

Former Tropical Storm Doksuri rapidly intensified to a typhoon during the past 12 hours. The inner end of a rainband wrapped around the center of Doksuri’s circulation. An eye at the center of circulation was evident on conventional and microwave satellite images. 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 Doksuri. Storms near the core generated strong upper level divergence that pumped mass away from the typhoon. The removal of large quantities of mass caused the surface pressure to decrease rapidly.

The size of the circulation around Typhoon Doksuri increased while Doksuri rapidly intensified. Winds to typhoon force extended out 70 miles (110 km) from the center of Doksuri’s circulation. Winds to tropical storm force extended out 215 miles (345 km) from the center. The Hurricane Intensity Index (HII) for Typhoon Doksuri was 13.9. The Hurricane Size Index (HSI) was 22.1 and the Hurricane Wind Intensity Size Index (HWISI) was 36.0.

Typhoon Doksuri will move through an environment very favorable for intensification during the next 24 hours. Doksuri will move over water where the Sea Surface Temperatures are 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 Doksuri is likely to continue to intensify rapidly during the next 24 hours. Doksuri could strengthen to the equivalent of a major hurricane.

Typhoon Doksuri will move around the southwestern side of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Doksuri toward the northwest during the next 24 hours. On its anticipated track, Typhoon Doksuri could be near northeastern Luzon within 48 hours. Doksuri could approach southern Taiwan in 72 hours.

Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Noru was 31.6. The Hurricane Size Index (HSI) was 11.1 and the Hurricane Wind Intensity Size Index (HWISI) was 42.7. Typhoon Noru was capable of causing regional severe damage.

Typhoon Noru will move around the southern side of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Noru toward the west during the next 72 hours. On its anticipated track, Typhoon Noru will move across central Luzon. The center of Noru could pass just north of Manila in a few hours. Typhoon Noru will bring strong, gusty winds to central Luzon. Severe damage could occur near the small core of Noru’s circulation. Widespread electrical outages are likely. Heavy rain will also fall over near the core of Typhoon Noru. Heavy rain is likely to cause flash floods in some locations.

Since the circulation around Typhoon Noru is small, it is likely to weaken quickly while it passes over Luzon. There is a chance that Noru could still be a typhoon when it reaches the South China Sea. Noru will move into an environment favorable for intensification when it moves over the South China Sea. Noru will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southern side of an upper level ridge over eastern China. The ridge will produce easterly winds that will blow toward the top of Noru’s circulation. Those winds will cause some vertical wind shear, but the wind shear will not be strong enough to prevent intensification.

Typhoon Noru could approach the coast of Vietnam in less than 72 hours. Noru could be a typhoon when it approaches the coast of Vietnam.

Typhoon Noru Rapidly Intensifies to Equivalent of Cat. 4 Hurricane East of Luzon

Typhoon Noru very rapidly intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Saturday. At 5:00 p.m. EDT on Saturday the center of Typhoon Noru was located at latitude 15.1°N and longitude 124.1°E which put it about 250 miles (400 km) east of Manila, Philippines. Noru was moving toward the west-southwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 190 m.p.h. (305 km/h). The minimum surface pressure was 920 mb.

Typhoon Noru intensified very rapidly from a tropical storm to the equivalent of a Category 4 hurricane in 24 hours. A small, pinhole eye with a diameter of 7 miles (11 km) formed at the center of Noru’s 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 Noru. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the typhoon. The removal of so much mass allowed the surface pressure to decrease rapidly.

The circulation around Typhoon Noru was relatively small. Winds to typhoon force extended out 25 miles (40 km) from the center of Noru. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation. The Hurricane Intensity Index (HII) was 33.3. The Hurricane Size Index (HSI) was 9.4 and the Hurricane Wind Intensity Size Index (HWISI) was 42.7. Typhoon Noru was capable of causing regional severe damage.

Typhoon Noru will move through an environment favorable for intensification during the next 12 hours. Noru will move over water where the Sea Surface Temperatures are 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 Noru could intensify to the equivalent of a Category 5 hurricane during the next 12 hours.

Typhoon Noru will move around the southern side of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Noru toward the west during the next 48 hours. On its anticipated track Typhoon Noru will make landfall on the coast of Luzon east-northeast of Manila. Typhoon Noru be the equivalent of a Category 4 hurricane when it makes landfall. Noru will produce severe wind damage. Heavy rain could cause flash floods. Typhoon Noru could produce a storm surge up to 15 feet (5 meters) along the east coast of Luzon.

The minimum surface pressure was 1000 mb.

The circulation around a small low pressure system just south of Honshu strengthened on Thursday night and the Japan Meteorological Agency designated the system as Tropical Storm Talas. The distribution of thunderstorms in Tropical Storm Talas was asymmetrical. Thunderstorms were occurring in bands in the northern and eastern parts of Talas’ circulation. Bands in the rest of the circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 45 miles (75 km) in the eastern side of Tropical Storm Talas. The winds in the western side of Talas were blowing at less than tropical storm force.

Tropical Storm Talas will move through an environment only marginally favorable for intensification during the next 24 hours. Talas will move over water where the Sea Surface Temperatures are near 26˚C. It will move under the eastern side of an upper level trough over eastern Asia. The upper level trough will produce strong southwesterly winds that will blow toward the top of Talas’ circulation. Those winds will cause moderate vertical wind shear. The wind shear will be strong enough to prevent significant intensification.

The upper level trough over eastern Asia will steer Tropical Storm Talas quickly toward the northeast during the next 24 hours. On its anticipated track Tropical Storm Talas will be near Tokyo in 18 hours. Talas will bring gusty winds and locally heavy rain to eastern Honshu. The small size of Talas’ circulation will limit the impact of the storm.
