The National Weather Service issued a coastal flood warning at 5:23 p.m. Thursday, which is also in effect for Middlesex County Friday between 7 a.m. and 1 p.m.

“Flooding of up to one foot above ground level is expected in low-lying areas near coastlines and tidal waterways,” the weather service comments. “Tides will remain elevated and there is a potential for further minor coastal flooding around high tide this weekend.”

“At this level, flooding begins on the most vulnerable roads in coastal and bayside communities, as well as along inland tidal waterways. Some partial or complete road closures are possible,” the weather service added. “If travel is necessary, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take necessary measures to protect flood-prone property.”

Weathering the Storm: Flood Safety Guidelines from the Weather Service

Flooding can pose a significant hazard, especially if you live in a flood-prone area or are camping in a low-lying region. To ensure your safety, the Weather Service offers important flood protection guidelines:

Go to a higher level:

If you live in a flood-prone area or are camping in low-lying terrain, the first step to safety is to move to higher ground.

Follow the evacuation instructions:

If local authorities issue an evacuation order, follow it immediately. Before leaving, secure your home by locking it.

Disconnect utilities and devices:

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

Avoid basements and flooded areas:

Avoid basements or flooded rooms with electrical outlets or cords. Preventing electrical accidents is crucial.

Quick evacuation for your safety:

If you notice sparks or hear any humming, crackling, cracking or popping noises, evacuate immediately. Do not enter water that may be electrically charged.

Stay away from flooding:

Never attempt to walk through flood water, even if it appears shallow. Just 15 cm of water with high current speed can violently knock you off your feet.

Find high ground if trapped:

If you become trapped by running water, get to the highest point available and call emergency services at 911.

During heavy rainfall, there is a risk of flooding, particularly in low-lying and flood-prone areas. Remember to never drive through water on the road, even if it appears shallow. According to the weather service, just 30 cm of fast-moving water can sweep away most cars. Prioritize your safety by staying informed and prepared.
