Understanding storm surges and thunderstorms

WHAT IS STORM SURGE?

A STORM surge is an abnormal rise in water level along a shoreline produced by a meteorological disturbance such as a hurricane. As the hurricane winds pass over the surface of the sea, they generate waves which flood the shoreline. The rise in water level and the hammering effect of the waves produce a storm surge, which can cause coastal erosion, flooding, scour roads, undercut sea walls and demolish buildings.

THUNDERSTORM/LIGHTENING SAFETY TIPS

The following tips are important guidelines to follow that may keep you safe when lightning is flashing:

IF YOU’RE OUTDOORS

Stay out of water, because it is a great conductor of electricity. Water-based activities such as swimming, scuba-diving, snorkelling are not safe and should be postponed or avoided during lightning.

If you’re outside, seek shelter in a house or building immediately. If there is no shelter around you, crouch down and put your feet together.

Avoid clothesline and metals in general – electrical wires, power tools, etc.

If you are in a motor vehicle, ensure the windows are completely shut.

IF YOU’RE INDOORS

Do not take a shower, wash your hands, dishes or do laundry, as water is a conductor of electricity.

Do not use corded telephones, as lightning may strike exterior phone lines.

Turn off, unplug and stay away from appliances, computers, TV sets, etc, as power surges from lightning and can cause serious damage.

I Stay away from windows and doors.

I Stay off verandah/porch.

IF SOMEONE IS STRUCK BY LIGHTNING

Call immediately for help. The injured person does not carry an electrical charge, so it is okay to touch them.
