On Wednesday at 11:51 p.m. a coastal flood advisory was issued by the National Weather Service valid from Thursday 3 p.m. until Friday 7 a.m. for Bristol and Plymouth counties.
The weather service says, “Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways (4.1 to 7.0 feet Mean Lower Low Water).”
“Flooding of lots, parks, and roads with only isolated road closures expected,” describes the weather service. “If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.”
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 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.
Keeping safe during floods: Expert advice 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’re in a flood-prone area, or if you’re camping in a low-lying spot, move to higher ground as a first step.
2. Adhere to 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 allows, disconnect your utilities and appliances. This reduces the risk of 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 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 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 intense rainfall, the risk of flooding increases, particularly in low-lying and flood-prone areas. It is imperative to avoid driving through any water on the road, even if it seems shallow. According to the weather service, most cars can be swept away by just 12 inches of rushing water. Stay safe by being prepared and informed.
