Your Guide Thunderstorms can occur anywhere in Fiji and do so more frequently than any other major natural hazard.

Notes/Vocabulary. How do clouds form?. when warm air & cold air meet, cold air pushes up the warm air and a cloud can form. when air rises and cools, the water vapor in the air condenses into tiny water droplets and forms a cloud.

A thunderstorm is a storm with thunder and lightning and typically includes heavy rainfall. A flood is when an overflowing of a large amount of water beyond its normal confines, especially over what is normally dry land.

The cumulus stage is marked by updrafts only. . These updrafts can reach values of up to 3,000 feet per minute and cause the cloud to build rapidly upwards, carrying super cooled water droplets well above the freezing level. .
