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 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).
