NATURAL WARNING SIGNS

THE SEA SWELLS

As a hurricane approaches, the sea starts to get rougher. This can happen days before landfall. Waves rise, lifting to heights of two metres or more.

THE CLOUDS CHANGE SHAPE

Hot air rising from the sea carries water into the sky, forming distinctive clouds. Cirrocumulus clouds look like ripples.

ANIMALS HIDE

Many animals sense changes in air pressure before a storm. In the sea, sharks, dolphins and lobsters move to deeper water.
