Deciphering advisories, watches, and warnings: Understanding weather alerts
- Flash flood warning: Take action!
A flash flood warning is issued when a flash flood is imminent or occurring. If you are in a flood-prone area, move immediately to high ground. A flash flood is a sudden violent flood that can take from minutes to hours to develop. It is even possible to experience a flash flood in areas not immediately receiving rain.
- 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.
When floods strike: Guidelines from the weather service for your protection
In flood-prone regions or while camping in low-lying areas, understanding and following the weather service flood safety guidelines can be a lifesaver:
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.
Follow evacuation orders:
If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.
Disconnect utilities and appliances:
If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.
Avoid basements and submerged areas:
Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.
Swift evacuation for your safety:
If you notice sparks or hear buzzing, crackling, snapping, or popping sounds, evacuate without delay. Do not enter water that may carry an electrical charge.
Stay away from floodwaters:
Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.
Seek higher ground when 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.
When heavy rain occurs, there is a potential for flooding, particularly in areas that are low-lying or prone to floods. It is crucial to never drive through water on the road, even if it appears shallow. According to the weather service, as little as 12 inches of fast-flowing water can carry away most vehicles. Prioritize your safety by staying informed and prepared.
