Breaking down weather alerts: 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 doesn’t guarantee that flooding will occur, but it signifies that the possibility exists.
Keeping safe during floods: Expert advice from the weather service
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’re in a flood-prone area, or if you’re camping in a low-lying spot, move to higher ground as a first step.
Follow evacuation orders:When local authorities issue an evacuation order, promptly comply. Before leaving, secure your home by locking it.
Disconnect utilities and appliances:If time allows, disconnect your utilities and appliances. This reduces the risk of 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.
Evacuate promptly for safety:If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity.
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.
Seek high ground if trapped:Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.
During periods of heavy rainfall, especially in low-lying and flood-prone areas, the risk of flooding escalates. Remember this crucial advice: never attempt to drive through water on the road, even if it appears shallow. According to the weather service, as little as 12 inches of rapidly flowing water can carry away most vehicles. Stay safe by being prepared and informed.
