As of Thursday afternoon, Podul’s eye was to the south of China’s Hainan Island, and is about 350 kilometers to the east of Vietnamese shores from Nghe An to Quang Tri provinces, according to the National Center for Hydro-Meteorological Forecasting.

It was carrying maximum wind speeds of 75-90 kph, the center added.

Podul is expected to make landfall with wind speeds of 60-75kph. It would devolve into a tropical depression within the next 36 to 48 hours, the center said.

Heavy rains should be expected across the country.

Central provinces of Thanh Hoa, Nghe An, Ha Tinh, Quang Binh, Quang Tri and Thua Thien-Hue, which is home to the popular tourist town Hue, should expect rainfall of up to 200 mm a day until Saturday. Rainfall of 180 mm a day is considered heavy.

Da Nang, the largest city in central Vietnam, is forecast to receive rainfall of 100-200mm from Friday to Saturday.

Hoa Binh, Son La, Yen Bai and Phu Tho Province in northern Vietnam should expect between 200-300mm of rainfall until Monday, and the nearby Hanoi between 50-120 mm.

Rainfall of between 100-150 mm is forecast in southern Vietnam, including Ho Chi Minh City, until Sunday, and 150-250 mm in the Central Highlands, home to Da Lat.

Hong Kong Observatory and the U.S. Navy forecast that the storm will make landfall at around 7 a.m.

U.S. weather forecasting service AccuWeather said Podul is expected to maintain its tropical storm intensity when it makes landfall before weakening into a depression over the rugged terrain of Vietnam, Laos and Thailand.

Areas from Da Nang to Ha Tinh would endure the worst of the storm’s impacts with strong winds and torrential rainfall from Thursday to Friday, it added.

Numerous localities, including Quang Binh, Thanh Hoa, Thua Thien-Hue and Kien Giang, home to Phu Quoc Island, have banned their ships and boats from sailing on Thursday as the storm approaches.

As many as 13 flights between Hanoi, Saigon, Hue, Thanh Hoa’s Vinh and Quang Binh’s Dong Hoi by carriers Vietnam Airlines, JetStar Pacific and Vasco will be cancelled Thursday, a press release by the Vietnam Airlines Group said.

Earlier this month Vietnam was struck by storm Wipha, which brought heavy rains, floods and landslides that left at least 10 dead and 11 missing in Thanh Hoa Province and its neighbors.

The country is hit by up to 10 tropical storms during the monsoon season between July and October. Four are expected this year.

Natural disasters, mostly floods, storms and landslides, killed 181 people last year and left 37 others missing and caused losses of around VND20 trillion ($858 million).

“By this morning (Thursday), the ships had returned to their harbors,” said Vu Manh Long, director of the Quang Ninh Port Authority of Inland Waterway.

Residents have been warned of the storm’s expected course on Wednesday, he said.

The Co To Island District of Quang Ninh, with a population of 5,000 people, could be the first locality to be hit by the storm.

Officials said there are around 300 tourists remaining on the island, including four foreigners.

300 of 350 ships have been recalled from the island, with the rest to follow on Thursday afternoon. Houses on the island have been strengthened.

Wipha, the third storm this year to appear on the East Sea, known internationally as the South China Sea, is expected to bring rough seas and strong winds in the Gulf of Tonkin this afternoon. Satellite images at around 2 p.m. showed thick clouds covering the entire gulf, including islands like Bach Long Vi, Cat Hai, Co To and Van Don.

Wipha’s eye is expected to be directly above Quang Ninh and the northern city of Hai Phong on Friday night, with a maximum wind speed of 90kph, according to the National Center for Hydro – Meteorological Forecasting.

It is likely to make landfall in coastal provinces from Quang Ninh to the northern province of Nam Dinh before weakening into a tropical depression, weather experts say.

The storm would cause downpours in northern Vietnam until Sunday. Hanoi should expect rainfall of 100mm to 200mm on Thursday. Rainfall of 180 mm a day is considered heavy.

Vietnam is hit by up to 10 tropical storms during the monsoon season, between July and October. This year, the country is expected to be directly affected by four storms and tropical depression.

Vietnam was struck by nine storms last year. Storm Mun hit northern and central provinces last month, killing two in the central province of Thanh Hoa.
