Are there any precursors to the rainstorm? How to prepare?

The precursors of heavy rain are strong winds, thunder and lightning, dark clouds and swallows flying very low. As long as you observe carefully, it is not difficult to find some small laws in life. So what preventive work should we do, for example,

1 ? If you are at home, close the doors and windows to prevent rain from blowing into the room and do a good job of moisture prevention. If you live in the countryside, you should take back the clothes in the yard to prevent getting wet. Everything in the yard that is afraid of getting wet should be put in a place where it won't rain. Then there is the electrical equipment at home. Usually heavy rain is accompanied by lightning and thunder. Then pay attention to the safety of electricity use, cut off the power supply of electrical equipment, prevent leakage and avoid the danger caused by convection with lightning. The mobile phone is turned off. Although using mobile phones in rainy days will not increase the probability of being struck by lightning, it is necessary to remind everyone that it is very dangerous to use fixed telephones in thunderstorm weather. This is because the telephone line connects outdoor and indoor, and outdoor objects are more likely to be hit than indoor ones. If telecommunications equipment or surrounding objects are struck by lightning, it may really endanger the users of the telephone, so try to avoid answering the phone or making a long story short.

2 ? If you are outdoors, you'd better go home before it rains. If you are far away from home, you can choose the nearest place to shelter from the rain and go home after the rainstorm. Pay attention to driving safety on the road, pay attention to whether the manhole cover is loose, and try to get off by bike. Also, pay attention to whether there are high-voltage lines falling off due to heavy rain to prevent leakage. Try to bypass the stagnant water section. Scratched trees and billboards should also be kept as far away as possible to avoid falling off and causing secondary injuries.

Summer is the rainy season. Remind everyone to close the doors and windows when going out, take rain gear, add clothes in time according to the weather, and prepare for rain and moisture.
