Description of the event

The death toll from tropical storm Kammri and subsequent floods has risen to at least 125 in northern Vietnam, with 38 others still listed as missing. Heavy rains followed by flash floods and landslides in Vietnam's northern mountainous provinces that began last week destroyed nearly 800 houses. Some 17,800 other buildings were flooded and damaged while 15,200 hectares (37,500 acres) of crops were wiped out.
