Storm surges

Surges are water movements caused by meteorological effects such as winds and atmospheric pressure changes – they are not easily predictable and require powerful computers and sophisticated software to predict just 36 hours in advance.

What are storm surges?

A storm surge is a large scale increase in sea level due to a storm. Low atmospheric pressure allows sea level to rise, and gale force winds combined with the Earth’s rotation force water towards the coastline – Read more →
