Your guide to 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 released when flooding is not expected to reach a severity level necessitating a warning. Nonetheless, it can still cause considerable inconvenience and, without exercising caution, potentially lead to situations that 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
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:
Move to 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.
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 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.
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.
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:
Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.
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. Stay safe by being prepared and informed.
Driving through downpours: Safety guidelines for wet roads
When heavy rain pours, the risk of flooding and treacherous roads rises. Here’s your guide from the weather service to staying safe during downpours:
Beware of swollen waterways:
In heavy rain, refrain from parking or walking near culverts or drainage ditches, where swift-moving water can pose a grave danger.
Maintain safe driving distances:
Adhere to the two-second rule for maintaining a safe following distance behind the vehicle in front of you. In heavy rain, allow an additional two seconds of distance to compensate for reduced traction and braking effectiveness.
Reduce speed and drive cautiously:
On wet roads, reducing your speed is crucial. Ease off the gas pedal gradually and avoid abrupt braking to prevent skidding.
Choose your lane wisely:
Stick to the middle lanes to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.
Visibility matters:
Enhance your visibility in heavy rain by turning on your headlights. Watch out for vehicles in blind spots, as rain-smeared windows can obscure them.
Watch out for slippery roads:
Be extra careful during the first half hour after rain begins. Grime and oil on the road surface mix with water to make the road slippery.
Keep a safe distance from large vehicles:
Don’t follow large trucks or buses too closely. The spray created by their large tires reduces your vision. Take care when passing them as well; if you must pass, do so quickly and safely.
Mind your windshield wipers:
- Overloaded wiper blades can hinder visibility. If rain severely impairs your vision, pull over and wait for conditions to improve. Seek refuge at rest areas or sheltered spots.
- When stopping by the roadside is your only option, position your vehicle as far off the road as possible, ideally beyond guardrails. Keep your headlights on and activate emergency flashers to alert other drivers of your position.
In the face of heavy rain, these precautions can make a significant difference in ensuring your safety on the road. Remember to stay informed about weather conditions and heed guidance from local authorities for a secure journey.
