Understanding the differences between advisories, watches, and warnings
Flash flood warning: Take action!
A flash flood warning is issued when a flash flood is either imminent or already occurring. In flood-prone areas, it’s crucial to move immediately to higher ground. A flash flood is a sudden and violent inundation that can develop within minutes to hours, and it can even happen in areas not currently experiencing rainfall.
Flood warning: Take action!
A flood warning is declared when flooding is on the verge of happening or is already underway.
Flood advisory: Be aware:
A flood advisory is issued when flooding is not expected to be bad enough to issue a warning. However, it may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.
Flood watch: Be prepared:
A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.
Keeping safe during floods: Expert advice from the weather service
Floods can pose a significant threat, especially if you live in a flood-prone area or find yourself camping in a low-lying region. To ensure your safety, the weather service offers essential flood safety guidelines:
1. Seek higher ground:If you reside in a flood-prone region or are camping in low-lying terrain, the first step to safety is relocating to higher ground.
2. Follow evacuation orders:If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.
3. Disconnect utilities and appliances:If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.
4. Steer clear of flooded basements and submerged areas:Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.
5. Swift evacuation for your safety:If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity.
6. Refrain from walking in floodwaters:Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.
7. Seek high ground if trapped:In the event you become trapped by moving water, make your way to the highest point available and contact emergency services by calling 911.
During heavy rainfall, the risk of flooding is heightened, especially in low-lying and flood-prone regions. Always remember never to drive through water on the road, no matter how shallow it appears. According to the weather service, as little as 12 inches of rapidly flowing water can carry away most vehicles. Prioritize your safety by staying informed and prepared.
