Greetings, friend @ahsansharif
These weather phenomena certainly bring drastic temperature changes; in your country, Pakistan, when temperatures soar, it significantly affects the elderly and those who work outdoors. As you rightly mentioned, the best course of action during this period is to drink plenty of water, stay in cool places, and take precautions against the extreme heat.
Given these climatic variations, certain areas of your country are at risk of experiencing unusual rainfall. Since half of the families in your country rely on agriculture, any resulting flooding would affect not only farmers but many other families as well. This makes it necessary to plan for the various scenarios that could arise due to the "Super El Niño" phenomenon.
All the best to you, my friend.
