Hurricanes and typhoons occur in different parts of the world, but the effect of both is typically the same. Flooding, high winds, extremely heavy rain, and often casualties occur during both of these kinds of storms, even though one type occurs in the Atlantic and the other occurs in the Pacific. They are similar in not only this way, but also in the way that you need to prepare for them.
Both of these storms can do serious damage to your local water supply and contaminate it with leaves, sticks, other debris, sewage, and sea water. This means that your local water supply is not safe to drink until your local government says that it is safe to do so after the storm is over. You should never drink the water out of your faucet while the storm is still going on outside and if possible, you should always evacuate your area if you are worried that your home could be flooded by the storm or the collapsing of surrounding dams or levees. The catastrophe of Hurricane Katrina in 2005 showed what can happen when levees break, so if you live in a similar area and a hurricane comes to town, take whatever you can carry and get out.
If you are not worried about your home flooding during this storm, then you will still need to save up as much water as you can to ride out the storm in your home. As mentioned earlier, drinking your tap water after the storm begins is not an option. You can boil it if you need to, but the bad thing about this is that boiling does not remove any chemicals from the water that it may have been contaminated with. You can purchase bottled water before the storm gets to your house or you can go the cheap way and save tap water in rinsed milk jugs. This is the easiest and cheapest way to do it.
Consider just how much water you are going to need. This amount will go up with the number of people that will be staying in your house and the amount of time you are expecting to be locked up in it while you are waiting for the storm to end. Each person should have access to one gallon of water for their use per day. The last thing that you want is to run out of drinking water, so if it is looking like your water supply might not last, forego bathing until the storm is over.
