According to China's meteorological regulations, rain with a rainfall of more than 50 mm in 24 hours is called? Heavy rain? . According to its precipitation intensity, it is divided into three grades, that is, the 24-hour precipitation is 50 ~ 99.9 mm, which is called? Heavy rain? ; ? Heavy rain? /kloc-below 0/00 ~ 249.9 mm; More than 250 mm is called? Heavy rain? .

Summer is a rainy season. Heavy rains often interrupt traffic, water supply and power supply in cities. In flood season, low-lying areas with poor drainage are prone to traffic paralysis, which affects the normal operation of the city and the normal life of citizens.

When you have to go out, avoid areas with serious water accumulation. On weekdays, don't litter, rubbish, etc. Enter the sewer to prevent blockage, resulting in rainstorm and water accumulation. When the rainstorm comes, can low-lying residential areas adapt to local conditions? Small encirclement? Measures, such as building a fence, placing water baffles or sandbags at the gate, and configuring small pumps. For residents living on the ground floor, the power sockets and switches at home should be moved to a safe place above the ground 1 meter.

Once the outdoor water overflows into the room, the power supply should be cut off in time to prevent the water from hurting people. When walking in outdoor water, pay attention to observation and walk near buildings to prevent falling into sewers, holes or pits. When drivers encounter too much water on the road or under the overpass, they should try to bypass and avoid forced passage. People living in mountainous areas should pay attention to prevent secondary disasters such as mountain torrents. Especially when the upstream water suddenly becomes turbid and the water level rises rapidly, special attention should be paid. Farmers who grow fruits and vegetables should effectively protect crops or harvest them in time before heavy rain. Residents living in high altitude and mountainous areas should be moved to safety areas in time and in an orderly manner before the rainstorm.
