On Monday at 9:25 a.m. the National Weather Service issued a flood advisory in effect until 12:30 p.m. for Mobile County.

The weather service describes, “Flooding caused by excessive rainfall is expected.”

“Minor flooding in low-lying and poor drainage areas,” explains the weather service. “Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles.”

Understanding the differences between advisories, watches, and warnings

• 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 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.

Staying safe during a flood: Recommendations 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:

1. 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.

2. Follow evacuation orders:

• If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.

3. Disconnect utilities and appliances:

• If time allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.

4. Avoid basements and submerged areas:

• Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.

5. 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.

6. 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.

7. 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.

During heavy rain, flooding is possible, especially in low-lying and flood-prone areas. Never drive through water on the road, even if it does not appear to be deep. It takes just 12 inches of rushing water to carry away most cars, according to the weather service. Stay safe by being prepared and informed.

Mastering wet roads: Safety tips for heavy rainfall

When heavy rain strikes, safety is paramount. Equip yourself with these guidelines from the weather service to navigate wet roads and avoid hazards:

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:

• 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:

• Stay toward the middle lanes – water tends to pool in the outside lanes.

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.

By following these safety measures, you can significantly reduce risks and ensure your well-being when heavy rain pours down. Stay informed about weather conditions and heed advice from local authorities to make your journey safe and sound.
