The most important thing to do here is to be fully prepared to minimize the potential damage it might cause. This depends on the effort of both individual and the government. The government should raise awareness of the public on the issue and equip people with essential skills to deal with various challenges and situations. Individual should pay attention to information about impending extreme weather, assess the damage it might cause. "Impending" can be used when something negative or bad (like extreme weather etc) is about to happen. Ex : Everyone is bracing themselves for the impending storm.
