After experiencing the heaviest rainfall in over 20 years, coupled with poor drainage systems, South Africa has declared 33 disaster areas due to flooding [rvd: Link]. Two of the largest rivers in the area [rvd: the Zambezi and the Okavango – Map] have risen to double their normal level. The flooding has killed more than 100 people and forced over 8,400 from their homes. Seven of the country’s nine provinces have sent in a request for aid. The flooding is also having a large impact on the shipping lines, preventing exports from leaving and preventing food and supplies from safely coming to most South African ports. Meteorologists believe the flooding is being caused by a weather cycle know as “La Nina,” which has been linked to flooding in Australia and the Philippines as well.
