Kalmaegi is predicted to reach the northern mountains in Laos at about 4pm today, but winds should be below 39 km per hour.
Prime Minister Nguyen Tang Dung yesterday asked local authorities, ministries and agencies to evacuate residents in low-lying areas, and help vessels anchor safely.
Northern localities prepared for typhoon Kalmaegi ("seagull" in Korean) before it made landfall on northern Hai Phong City and Quang Ninh Province..
Residents living in mountainous areas with high risks of landslides and flash floods were evacuated, while fishermen were ordered to quickly go ashore or find the nearest safe anchorage.

Residents raising fish or shrimp in around 7,600 aquaculture cages were evacuated.
In Hai Phong City, authorities mobilised nearly 40,000 soldiers and militia to prepare for search and rescue efforts and reinforce the dyke system in order to prevent floods.
Tran Xuan Hoang, deputy head of the provincial Sub-committee on Marine Fisheries Safety, said that all fishing vessels came ashore by 9am yesterday. Authorised agencies also helped local farmers harvest summer-autumn rice before the storm hit.
In Thai Binh, 8,000 people who raised oysters near the sea, worked at aquaculture farms or lived in dangerous areas were evacuated by noon yesterday.

Warnings for Ha Noi and mountainous provinces
Ha Noi is forecast to be inundated this morning by hours of torrential rain that could reach 300mm, said director of the National Centre for Hydro-meteorological Forecasting Hoang Duc Cuong.
Torrential rains were also predicted to shower northern provinces with rainfall reaching 250mm or even 400mm in mountainous provinces. Ten northern mountainous provinces such as Lang Son, Tuyen Quang, Ha Giang, Yen Bai, Dien Bien and Son La were put on high alert for landslides and flash floods during the storm.
Rough seas were expected in the northern part of the Bac Bo (Tonkin) Gulf, including island districts of Bach Long Vy, Co To, Cat Hai and Van Don, with strong winds and waves reaching six metres in height. After making landfall, the storm was expected to weaken into a tropical low-pressure system.
