A flood is a natural occurrence where water covers once-dry land. It can have a positive impact on an ecosystem, especially one experiencing prolonged drought. Unfortunately for most, it can also have a deadly effect.
Flooding typically happens after heavy rainfall when waterways – like rivers, creeks and ponds – can’t hold the new water. In coastal cities, tropical cyclones, tsunamis and high tide combined with high river levels cause floods.
Natural disasters are worsening with global warming. As temperatures rise, so does the risk of tropical cyclones and intense storms. Experts say a warmer climate could produce fewer storms – but they will be much more destructive.
If you get caught in a flood situation, you can reduce health risks by avoiding the water.
