Measures before a typhoon approaches In preparation for high waves and storm surges
In coastal areas, there is a risk of high waves and storm surges due to typhoons, so it is necessary to be prepared while paying attention to the following three points.
First, above all, stay away from coastal areas where there is a risk of high waves and storm surges. Even if you are worried regarding the state of the sea and boats, please do not go to see them.
Second, check the time of spring tide and the time of high tide. When high waves and storm surges from a typhoon coincide with high tides, there is a risk of serious damage, such as flooding and inundation of roads around the coast.
Third, evacuate (move) while you can act safely. If the sea spray surpasses the seawall facilities and rushes onto the coastal road, there is a risk of flooding and making passage dangerous. Check traffic information such as road closures and speed restrictions frequently and evacuate early.
Measures before a typhoon approaches Prepare for a storm
The scary thing regarding typhoon storms is that when it hits, you can’t move. Therefore, it is necessary to confirm and prepare for three points in advance once morest storms.
First, clean out rain gutters and gutters to improve drainage. If the gutters are clogged with fallen leaves, etc. and the water does not flow, the roads will be flooded.
Second, take measures such as firmly fixing outdoor items that are easily blown away (clothing poles, potted plants, trash cans, etc.) or putting them indoors. At shops, etc., please check to make sure that signs are not blown away or vending machines are knocked over.
The third item was blown away by the storm, so lock the windows and close the shutters if there are any to prevent the glass from breaking. If you put packing tape on the window glass, it will be able to withstand the wind pressure. If the glass breaks, keep the curtains closed to prevent splinters from scattering.
