Typhoon Noru Makes Landfall in Central Vietnam

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

Typhoon Noru moved over the South China Sea toward Vietnam on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Typhoon Noru was located at latitude 15.9°N and longitude 113.3E which put it about 380 miles (615 km) east of Da Nang, Vietnam. Noru was moving toward the west at 20 m.p.h. (32 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 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). The minimum surface pressure was 997 mb.
