The National Weather Service issued a coastal flood warning at 1:15 p.m. Thursday, effective for Manhattan and Staten Island between 6 a.m. and 10 a.m. Friday.

“Flooding of one to two feet above ground level is expected in vulnerable areas near shore and shore,” the weather service says. “With flood cycles continuing through Saturday, further coastal flooding is possible.”

“Minor flooding in the more vulnerable locations near the water and the coast. Some roads and low-lying properties, including parking lots, parks, lawns, and homes and businesses with basements near the water, will experience minor flooding,” the weather service describes. “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.”

Understand the differences between notices, watches and warnings

• Flash flood warning: take action!

A flash flood warning is issued when a flash flood is imminent or already occurring. In flood-prone areas, it is important to move to higher ground immediately. A flash flood is a sudden and intense flood that can develop within minutes to hours and can occur even in areas where there is currently no rain.

• Flood warning: take action!

A flood warning is issued when flooding is threatened or occurs.

• Flood Warning: Be Aware:

A flood warning is issued when flooding is not expected to reach a level of severity requiring a warning. However, it can cause considerable inconvenience and, if not exercised caution, could potentially lead to life-threatening and/or property-threatening situations.

• Flood watch: Be prepared:

A flood warning is issued when conditions are favorable for flooding. That doesn't mean there will be flooding, but it is possible.

Weather Service Flood Prevention Guidelines: Weathering the Storm

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:

Find higher ground:

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:

Stay away from basements or rooms where electrical outlets or cords are submerged. This helps prevent electrical accidents.

Quick evacuation for your safety:

If you notice sparks or hear humming, crackling, snapping or popping noises, evacuate immediately. Avoid water that may be electrically charged.

Do not walk in flood waters:

Never attempt to walk through flood water. Even 6 inches of fast-moving water can force you off your feet.

In the event of an accident, seek higher ground:

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

During periods of heavy rainfall, the risk of flooding increases, particularly in low-lying and flood-prone areas. It is important to avoid driving through water on the road, even if it appears flat. According to the weather service, most cars can be swept away in water depths of just 30 cm. Prioritize your safety by staying informed and prepared.
