Deciphering advisories, watches, and warnings: Understanding weather alerts

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.

Weather service flood safety guidelines: Weathering the storm In flood-prone regions or while camping in low-lying areas, understanding and following the weather service flood safety guidelines can be a lifesaver:

Move to 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.

Adhere to 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.

Steer clear of flooded 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 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 if they appear shallow. Just 6 inches of fast-moving water can forcefully sweep you off your feet.

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.

When heavy rain occurs, there is a risk of flooding, particularly in low-lying and flood-prone regions. It is important to never attempt to drive through water on the road, regardless of how deep it appears. According to the weather service, as little as 12 inches of rushing water can sweep away most vehicles. Prioritize your safety by staying informed and prepared.
