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 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.

When floods strike: Guidelines from the NWS for your protection

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 NWS 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 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.

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 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 NWS, 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 strikes, safety is paramount. Equip yourself with these guidelines from the NWS to navigate wet roads and avoid hazards:

Beware of swollen waterways:

During heavy rain, avoid parking or walking near culverts or drainage ditches, where swift-moving water can pose a serious risk.

Maintain safe driving distances:

Use the two-second rule to maintain a safe distance from the car in front of you and allow an extra two seconds in heavy rain.

Reduce speed and drive cautiously:

If it is raining and the roads are wet, slow down. Take your foot off the accelerator and let your speed drop gradually. Never use the brakes suddenly because this may cause the car to skid.

Choose your lane wisely:

Stick to the middle lanes on multi-lane roads to minimize the risk of hydroplaning, as water tends to accumulate in outer lanes.

Prioritize visibility:

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:

The initial half-hour of rain is when roads are slickest due to a mixture of rain, grime, and oil. Exercise heightened caution during this period.

Keep a safe distance from large vehicles:

Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and pass them swiftly 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.

• If the roadside is your only option, pull off as far as possible, preferably past the end of a guard rail, and wait until the storm passes. Keep your headlights on and turn on 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.
