A storm surge is a rise in the sea level above the normal tide, usually accompanying a low pressure system (i.e a cyclone, tropical cyclone or hurricane). Storm surges are caused by the effects of strong winds and low atmospheric pressure, which affect tides and push the ocean towards shallow waters of the coastline.

Why storm surges are so dangerous?

- Height and Speed: Storm surges can be as high as 20 feet and travel as quickly as 25- 30 mph. In combination, the height and speed of storm surges can cause severe flooding and destruction along coastlines.

- Coastal damage: When a storm surge reaches land, it can carry with it debris and cause significant damage to buildings, infrastructure, and properties close to the shore.

- Impact on the Environment: Storm surges can erode beaches, cause coastal erosion, displace marine life, damage fragile habitats, and result in long term ecological imbalances in the area.

- Human Risks: Storm surges can be unpredictable and can come without warning, leading to loss of life if populations near coastlines are not adequately prepared or warned in time.
