Weather alert breakdown: advisories, observations and warnings

• Flash flood warning: take action!

A flash flood warning is issued when a flash flood is imminent or is already occurring. If you are in a flood-prone area, get to higher ground immediately. A flash flood is a sudden, severe flood that can develop from minutes to hours. It is even possible to experience flash flooding in areas where there is no immediate rain.

• Flood warning: take action!

A flood warning is issued when flooding is imminent or already underway.

• Flood warning: Please note:

A Flood Warning is issued when flooding is not expected to reach a level of severity that would warrant a warning. However, such a warning may cause significant inconvenience and, if ignored, may result in situations threatening life and/or property.

• Flood warning: Be prepared:

A flood warning is issued when conditions are favourable for flooding. It does not guarantee that flooding will occur, but indicates that the possibility exists.

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:

Move to higher ground:

If you are in a flood-prone area or camping in a low-lying area, the first step 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 will reduce the risk of electrical hazards during flooding.

Avoid basements and flooded areas:

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

Fast evacuation for your safety:

If you notice sparks or hear buzzing, crackling, popping or banging noises, leave the area immediately. Avoid water that may be live.

Stay away from floods:

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 become trapped in running water, go to the highest possible point and call 911.

During heavy rain, the risk of flooding increases, especially in low-lying and flood-prone areas. It is important to avoid driving through water on the road, even if it appears shallow. According to the weather service, most cars can be swept away by just 30 cm of water. Stay safe by being prepared and informed.

Driving in heavy rain: safety tips for wet roads

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:

Avoid parking or walking in close proximity to culverts or drainage ditches, as fast-flowing water may sweep you away during heavy rain.

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:

Improve your visibility in heavy rain by turning on your headlights. Pay particular attention to vehicles in your blind spot, as rain-smeared windows can obscure them.

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 you can only stop at the side of the road, position your vehicle as far from the road as possible, ideally behind guard rails. Leave your headlights on and activate 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.
