Typhoon Noru made landfall on the coast of central Vietnam near Da Nang on Tuesday evening. At 7:00 p.m. EDT on Tuesday the center of Typhoon Noru was located at latitude 16.1°N and longitude 108.1°E which put it about 5 miles (10 km) north of Da Nang, Vietnam. Noru was moving toward the west at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h). The minimum surface pressure was 959 mb.

The core of Typhoon Noru made landfall near Da Nang, Vietnam on Tuesday evening. The distribution of thunderstorms around Noru became asymmetrical as it approached the coast of Vietnam. Many of the thunderstorms were occurring in the western half of Noru’s circulation. Typhoon Noru was moving under the southern part of an upper level ridge over China. The ridge was producing easterly winds that were blowing toward the top of Noru’s circulation. Those winds were causing vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms.

Winds to typhoon force extended out 25 miles (40 km) from the center of Typhoon Noru. Winds to tropical storm force extended out 120 miles (195 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Noru was 19.2. The Hurricane Size Index (HSI) was 10.9 and the Hurricane Wind Intensity Size Index (HWISI) was 30.1. Typhoon Noru was capable of causing regional serious damage.

Typhoon Noru will move south of a high pressure system over China. The high pressure system will steer Noru toward the west during the next 36 hours. Typhoon Noru will weaken as it moves farther inland. On its anticipated track Typhoon Noru will move across central Vietnam during the next 12 hours. Noru will move over southern Laos and eastern Thailand. The strongest winds will occur in the area around Da Nang and Hue. Typhoon Noru will drop locally heavy rain over central Vietnam, southern Laos and eastern Thailand. Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Kulap strengthened gradually southeast of Japan. At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Kulap was located at latitude 31.7°N and longitude 145.2°E which put it about 395 miles (640 km) southeast of Tokyo, Japan. Kulap was moving toward the northeast at 21 m.p.h. (33 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 988 mb.

Typhoon Noru Moves Toward Vietnam

The minimum surface pressure was 964 mb.

Typhoon Noru strengthened on Monday afternoon as it moved toward central Vietnam. A small circular eye was present 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 upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Noru increased in size on Monday. Winds to typhoon force extended out 50 miles (80 km) from the center of Noru’s circulation. Winds to tropical storm force extended out 180 miles (290 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Norw was 17.8. The Hurricane Size Index (HSI) was 16.9 and the Hurricane Wind Intensity Size Index (HWISI) was 34.7. Typhoon Nora was capable of causing regional serious damage.

Typhoon Noru will move through an environment favorable for intensification during the next 24 hours. 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 is likely to intensify during the next 24 hours. Noru could strengthen to the equivalent of a major hurricane.

Typhoon Noru will move around the southern side of a high pressure system over China. The high pressure system will steer Noru toward the west during the next 24 hours. On its anticipated track Typhoon Noru will hit the coast of Vietnam near Da Nang in 24 hours. Typhoon Noru will be capable of causing major damage when it hits central Vietnam. Noru will bring strong, gusty winds and locally heavy rain to central Vietnam. Heavy rain is likely to cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Kulap passed near Iwo To. At 5:00 p.m. EDT on Monday the center of Tropical Storm Kulap was located at latitude 27.4°N and longitude 141.8°E which put it about 140 miles (225 km) north-northeast of Iwo To. Kulap was moving toward the north at 20 m.p.h. (32 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).

Typhoon Noru Hits Luzon

Typhoon Noru hit Luzon on Sunday morning. At 5:00 a.m. EDT on Sunday the center of Typhoon Noru was located at latitude 15.1°N and longitude 121.9°E which put it about 105 miles (165 km) east-northeast of Manila, Philippines. Noru was moving toward the west at 14 m.p.h. (22 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 926 mb.

Small, but powerful Typhoon Noru hit the coast of Luzon east-northeast of Manila on Sunday morning. Winds to typhoon force extended out 30 miles (50 km) from the center of Typhoon Noru. 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. Widespread electricity outages are likely.
