To some culture raining on the day of the move is a bad omen. But, don't take this belief against you if you happen to be moving on rainy day. Consider it as a blessing pouring from heaven. Even nature conspires with you and the day of your move will be a day of luck to you if you welcome it with a good heart.
So, be prepared. Instead of fretting start collecting blankets and other covers and wraps that will be used in shielding your furniture items from the rain. If you have wooden furniture items, then you have to cover it with cloths so it wouldn't water spots.
For floor protection, you can use an absorbent mat that will prevent mud from forming on your floor. Place your mats on the doorsteps so that whenever you enter your home you wouldn't be all soaked up and you will not bring mud inside the house. There are carpets that are resistant to tearing and ripping and you can have one of those to achieve better protection.
Heavy rain can annoy you but, remember, you have to have to guts to face it and be optimistic about it instead. Take advantage of the many options available and use shield and protection to save your properties from getting damaged.
