Understanding the differences between 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 occurring.
- 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. This does not mean that flooding will occur, but it is possible.
Stay safe during floods: Expert tips from the weather service
Flooding can pose a significant threat, especially if you live in a flood-prone area or are camping in a low-lying region. To ensure your safety, the Weather Service offers important flood safety guidelines:
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 will reduce the risk of 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.
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.
If you are trapped, seek higher ground:
If you become trapped in running water, go to the highest possible point and call 911.
During heavy rain there is a risk of flooding, especially in low-lying and flood-prone areas. Remember never to drive through water on the road, even if it is not deep. According to the weather service, as little as 30 cm of fast-moving water can sweep away most cars. Stay safe by being prepared and informed.
