Storm Wipha made landfall along the coastline between Hung Yen and Ninh Binh Provinces at 10 a.m. Tuesday, packing 64–102 kph winds, before moving southwest and weakening.

Typhoon Wipha has made landfall in northern Vietnam, prompting large-scale emergency preparedness, after deadly floods and heavy rain in the Philippines left at least five dead and thousands displaced.

Tropical Storm Wipha is edging slowly toward Vietnam and is set to cross the coast near the northern port city of Haiphong around noon on Tuesday, bringing heavy rain that could lead to flash flooding.

Vietnam's Prime Minister put coastal provinces on emergency footing for Typhoon Wipha, saying it could cause flooding and landslides, as airlines cancelled flights ahead of the storm's expected landfall early on Tuesday.

Wipha was a tropical storm in the Gulf of Tonkin Monday afternoon China Standard Time, the Joint Typhoon Warning Center said in its latest advisory. Typhoon season is year-round; however, most typhoons form from early July through mid-December.
