A rainstorm refers to average precipitation reach or exceed 50mm within 24 hours. Rainstorm is often characterized by its sudden occurrence in a local area, which could flood city streets, paralyze traffic, and cause dilapidated buildings collapse. Extremely heavy rainstorm could lead overflow of rivers, mountain torrents, mud-rock torrents, landslides, and demolition of houses.

Tips:

 ·Set up a doorsill or a board in front of your door to keep out the water when encountering waterlogging.
 ·When flood water gets into your house, cut off electricity to prevent electric shock.
 ·Be careful when you walk outdoors, keep walking alongside buildings so as not to fall in to wells or pits
 ·Drivers should avoid deep water on the road or overpasses.

Suggestions:

 ·Do not throw away garbage into the drainage pipes for they may jam the pipes and cause waterlogging.
 ·People who live in single-storey houses should carefully check your houses before rain season, and repair the roofs when necessary. 
 ·Do not go out during a rainstorm. Avoid deep water when traveling outdoors.
 ·When traveling in the countryside, take precaution against mountain torrents. When water from upstream suddenly become muddy, or the water level rises too quickly, you should take actions.
