The Philippines is a tropical country. It means that there are only two seasons - sunny and rainy. It is good to get prepared for frequent and sudden rains that may occur as soon as you go outdoors.
A typhoon is the term for a tropical storm that happens in the Philippines and in nearby countries. Typhoons occur at an average of 1 per month during the rainy season.
No one wants to get wet unexpectedly. Aside from getting wet by the rain, heavy rainfall as a result of storms will likely result to floods and power outages in the country.
