On Sunday at 3:58 a.m. the National Weather Service issued a coastal flood statement valid for Sunday between 6 p.m. and 10 p.m. for Hudson, Bergen, Essex and Union counties.

The weather service adds, “Up to 1/2 foot of inundation above ground level expected in vulnerable areas near the waterfront and shoreline.”

“Brief minor flooding of the most vulnerable locations near the waterfront and shoreline,” states the weather service. “Do not drive through flooded roadways.”

Understanding the differences between 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 issued when flooding is imminent or occurring.

• 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 does not mean flooding will occur, but it is possible.

Be flood-ready: Expert guidance from the weather service for your safety

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:

• When local authorities issue an evacuation order, promptly comply. Before leaving, secure your home by locking it.

3. Disconnect utilities and appliances:

• If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.

4. Steer clear of flooded 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 sounds, evacuate without delay. Do not enter water that may carry an electrical charge.

6. 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.

7. 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 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. Prioritize your safety by staying informed and prepared.

Mastering wet roads: Safety tips for heavy rainfall

When heavy rain sets in, the risk of flooding and hazardous driving conditions rises. Whether it’s prolonged rainfall or rapid runoff, being prepared is essential. Here are some valuable safety tips from the weather service to ensure you stay safe in heavy rain:

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:

• The two-second rule for following distance is your ally in heavy rain. Extend it to four seconds to ensure safe spacing in adverse conditions.

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 to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.

Prioritize visibility:

• Turn on your headlights and be careful of other vehicles to the rear and in blind spot areas as they are especially difficult to see through rain-spattered windows.

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 limits your sight, pull over and wait for conditions to improve. Seek refuge at rest areas or protected 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.

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.
