TORONTO, CANADA--(Marketwired - Nov 9, 2013) - After pummelling the Philippines on Friday, Typhoon Haiyan is expected to pack winds of up to 200kph as it makes landfall in Vietnam Sunday morning local time.

One million people could be affected, including 330,000 children.

"We're preparing for dangerous winds, flash flooding and significant damage to infrastructure. We're especially concerned about the thousands of children and their families who live in low-lying areas or in homes that might not be able to withstand the full force of Typhoon Haiyan," said Tuan Doan, Save the Children's Deputy Country Director in Vietnam.

"Save the Children has been working with communities to prepare for natural disasters like this one, and our teams are on alert, ready and waiting to respond."

The typhoon is expected to make landfall across central Vietnam between 4am and 10am, including provinces that were severely hit by the Wutip and Nari Typhoons last month.

Save the Children's Emergency Response Team is on standby, and will move to the worst affected areas once the storm has passed to assess what help is needed. Save the Children has about 2,000 household kits, 1,000 hygiene kits and more than 3,000 education kits ready for distribution should the need arise.

Save the Children has been working in Vietnam since 1990, and in the past five years have facilitated Disaster Risk Reduction interventions. This includes preparing communities for disasters by running evacuation drills and providing basic rescue equipment like rope, flashlights and life vests.
