The rainstorm in Beijing darkened instantly. What should we do in the face of heavy rain?

With the arrival of summer, the rain is getting heavier and heavier. According to the Beijing Meteorological Observatory, after two o'clock, heavy rain began to affect the city from west to east, and hail appeared in Shijingshan and Fengtai. By 4 pm, the rainfall in Beijing was 3.8 mm, the urban area was 4.8 mm, the maximum rainfall in Mentougou Shenquan Gorge was 22.8 mm, and the maximum hourly rainfall also appeared at the station. The rainfall from 15 to 16 was 22.8 mm.

According to the forecast, there will be thunderstorms before 9 pm in this city, with heavy local rainfall, which may be accompanied by strong convective weather, short-term strong winds and hail above magnitude 7. It is estimated that the rainfall in the urban area will last until 9: 00 pm 10 pm, and the whole city will basically end at 9: 00 pm. Rainfall is unevenly distributed, with rainfall reaching 3-8 mm in most areas, 20-25 mm in some areas, and the maximum hour is 20 mm.

When a thunderstorm comes, the sky is as dark as evening. According to the strong weather forecast center of the Central Meteorological Observatory, similar phenomena have occurred in many areas, which have adversely affected normal life and work, especially traffic jams and inconvenient travel. The reason is the phenomenon caused by strong convective weather. In strong convective weather, the cloud base is very low and the clouds are deep, which blocks the sunshine and forms the phenomenon of staying up late during the day and coming out at night. This is a common phenomenon in strong convective weather.

The Beijing Meteorological Observatory issued a blue lightning warning signal at a quarter to one and upgraded it to a yellow lightning warning signal at 3: 30. A yellow warning signal for hail has been issued in Mentougou and other places. Everyone needs to guard against the adverse effects of night thunderstorms on urban traffic peaks, and public travel needs to pay attention to rain and lightning protection.

Main measures to prevent rainstorm

1. Try not to go out during the rainstorm. When you have to go out, you should bypass the area with serious water accumulation as much as possible and walk close to the building to prevent falling into manholes and pits.

2. Close the air valve and the main power switch.

3. In order to prevent small-scale waterlogging in residential buildings, water barriers, sandbags or soil ridges can be set at the door according to local conditions, and they can be moved to a safe place in time.
