Description of the event

Tropical Storm Haiyan made landfall in Vietnam early in the morning on 11 November 2013. 11 people were reported killed hundreds of thousands evacuated from affected areas during the storm.

Though Haiyan had weakened considerably since it passed over the Philippines the week before, it was classified as a severe Tropical Storm by the time it reached Vietnam. There had been concerns that the storm would have a major impact on the nation, which resulted in the government taking the precaution of evacuating approximately 800,000 people. The storm weakened further as it approached Vietnam, however, and it's impact was far less devastating than anticipated.

Haiyan brought as much as 40 cm of rain over some areas and winds 147 km/h (91 mph) strong. While the primary impact on the Philippines had been the typhoon's powerful winds, the storm gathered moisture as it crossed the South China Sea over the weekend causing heavy rain to fall over Vietnam.

Haiyan's impact on Vietnam was in the northern part of the country.
