Floods May 29-31 2021

 Today we have to blog about the floods.

The flooding has made people leave their houses and schools were closed cause of the rain and damage it did to the roofs and other parts. The flooding caused a few bridges to be closed and broken and made people move to safety (places away from the floods) and it was getting very dangerous to drive in. It's gotten way better now there is no rain and its getting hotter the weather is way better now. Here is a picture of Christchurch in flood.
