Weather Service Flood Safety Guidelines: Weathering the Storm

In flood-prone regions or when camping in low-lying areas, understanding and following the weather service’s flood safety guidelines can be life-saving:

Find higher ground:

If you live in a flood-prone area or are camping in low-lying areas, the first step to safety is to move to higher ground.

Follow evacuation instructions:

If local authorities issue an evacuation order, obey it immediately. Secure your home by locking it before leaving.

Disconnect utilities and equipment:

If time permits, unplug your utilities and appliances. This precaution will minimize electrical hazards during flooding.

Avoid flooded basements and flooded areas:

Avoid basements or rooms where sockets or cables are under water. This way you can avoid electrical accidents.

For safety reasons, evacuate immediately:

If you notice sparks or hear buzzing, crackling, popping or banging noises, evacuate immediately. Do not enter water that may be live.

Avoid going into flood water:

Never attempt to walk through flood water, even if it appears shallow. Even 6 inches of fast-flowing water can sweep you off your feet with full force.

Seek higher ground if you are trapped:

If you are trapped in running water, go to the highest possible point and dial 911 to contact emergency services.

During heavy rain, the risk of flooding is increased, especially in low-lying and flood-prone areas. Always remember to never drive through water on the road, no matter how shallow it appears. According to the weather service, as little as 30 cm of fast-moving water can sweep away most vehicles. Your safety is paramount by staying informed and prepared.

Mastering wet roads: safety tips for heavy rain

When heavy rain sets in, the risk of flooding and dangerous driving conditions increases. Whether it’s persistent rain or rapid runoff, it’s important to be prepared. Here are some valuable safety tips from the weather service to help you stay safe during heavy rain:

Be careful with fast water flow:

During heavy rain, do not park or walk near culverts or drainage ditches as fast-flowing water can pose a great danger.

Keep the safety distance:

Use the two-second rule to maintain a safe distance from the car in front of you, and add an additional two seconds in heavy rain.

Slow down and be careful:

When it is raining and the roads are wet, slow down. Take your foot off the accelerator and reduce the speed gradually. Never brake suddenly, otherwise the car may skid.

Choose your lane carefully:

On multi-lane roads, stay in the middle lane to minimize the risk of aquaplaning, as water tends to collect in the outer lanes.

Prioritize visibility:

In heavy rain, turn on your headlights to improve your visibility. Watch for vehicles in your blind spot as rain-smeared windows can obscure their view.

Be careful of slippery roads:

During the first half hour of rain, the roads are most slippery due to a mixture of rain, dirt and oil. Be especially careful during this time.

Keep a safe distance from large vehicles:

Do not drive too close behind large trucks or buses. The spray created by their large tires will limit your visibility. Also be careful when overtaking; if you must overtake, do so quickly and safely.

Pay attention to your windshield wipers:

• Heavy rain can overload the wiper blades. When visibility is so limited that you can no longer see the edge of the road or other vehicles at a safe distance, it is time to stop and wait for the rain to subside. It is best to stop at rest areas or other sheltered areas.
• If the side of the road is your only option, pull over as far as possible, preferably to the end of a guardrail, and wait for the storm to pass. Keep your headlights on and turn on your hazard lights to alert other drivers to your position.

By following these safety measures, you can significantly reduce the risks and ensure your well-being during heavy rain. Stay informed about weather conditions and follow the advice of local authorities to ensure your trip is safe and unharmed.
