include tropical cyclones (also known as typhoons and hurricanes), thunderstorms, hailstorms, tornados, blizzards, heavy snowfall, avalanches, coastal storm surges, and floods including flash floods, drought, heatwaves, and cold spells.

Hydrometeorological conditions can also be a factor in other hazards such as landslides, wild fires, locust plagues, epidemics, and in the transport and dispersal of toxic substances and volcanic eruption material. (UNISDR 2007)

Tropical cyclones are giant whirlwinds, which are locally known as bagyo. Rainfall associated with a tropical cyclone can be intense over a long period of time.

The eye of the tropical cyclone is the low-pressure centre but the outer sides are high-pressure areas that move in a circular manner.
