At 3:38 a.m. on Thursday, the National Weather Service issued an updated coastal flood advisory for Nassau County that was effective from 10 a.m. to 2 p.m.
The National Weather Service reports, “Up to one foot of inundation above ground level expected in vulnerable areas near the waterfront and shoreline.”
“Slight flooding in the more susceptible areas close to the shoreline and waterfront. According to the weather service, there will be moderate flooding on some roads and low-lying structures, such as parking lots, parks, lawns, and houses and businesses with basements close to the waterfront. “Give yourself more time if you have to travel because some roads can be closed. Avoid driving over water that is unknown in depth or around obstacles. Protect property that is vulnerable to flooding by taking the appropriate measures.
Understanding the differences between advisories, watches, and warnings
- Flash flood warning: Take action!
When a flash flood is either approaching or has already occurred, a warning is given. Moving to higher ground right away is essential in places that are prone to flooding. A flash flood is a quick, intense flood that can form in a matter of minutes to hours and even occur in places that aren’t currently receiving any rain.
- Flood warning: Take action!
When flooding is about to occur or has already started, a flood warning is issued.
- Flood advisory: Be aware:
When flooding is not predicted to become severe enough to warrant a warning, a flood advisory is issued. However, it still has the potential to be extremely inconvenient and, if careless, to result in circumstances that endanger life and/or property.
- Flood watch: Be prepared:
When the weather is conducive to flooding, a flood watch is issued. Although it doesn’t ensure flooding will happen, it does indicate that it is a potential.
Keeping safe during floods: Expert advice from the weather service
Knowing and adhering to the weather service’s flood safety recommendations can be extremely helpful when camping in low-lying areas or in places that are prone to flooding:
Look for higher ground.
Moving to higher ground is the first line of defense if you live in an area that floods easily or are camping in a low-lying area.
Respect evacuation directives:
Respond quickly to any evacuation orders issued by local authorities. Secure your home by locking it before you leave.
Cut off appliances and utilities:
Disconnect your appliances and utilities if you have the time. By taking this precaution, electrical dangers during flooding are reduced.
Avoid drowned places and flooding basements:
Avoid basements or rooms with electrical outlets or cords submerged in water. This lessens the chance of electrical mishaps.
Quick evacuation to keep you safe:
Evacuate right away if you see sparks or hear popping, crackling, snapping, or buzzing noises. Avoid going into water that might be electrically charged.
Avoid going on foot in floodwaters:
Never try to cross flooding on foot. Six inches of quickly flowing water can knock you off your feet with force.
When stuck, look for higher ground:
If you find yourself caught by flowing water, get to the highest position you can and call 911 to get help.
Flooding is more likely to occur during times of heavy rainfall, especially in low-lying and flood-prone locations. Driving through any water on the road, even if it appears to be shallow, must be avoided. The weather service claims that 12 inches of flowing water is enough to sweep away the majority of autos. Be knowledgeable and ready to stay safe.
