Preparing for a Nor'Easter

What Long Island Homeowners Need to Know ** Article written September 24, 2026

Fall on Long Island brings pumpkin patches, cider donuts...and occasionally, a nor'easter. This weekend, forecasters are tracking a storm system expected to bring heavy rain, strong winds, and coastal flooding to the area. Whether you're a longtime Long Islander or new to the area, here's what you need to know to keep your home and family safe.

What Exactly is a Nor'Easter?

Before we begin, let's discuss what we're preparing for. A nor'easter is a powerful coastal storm that gets its name from the northeasterly winds that blow in off the Atlantic as the storm moves up the East Coast. Unlike a quick-moving summer thunderstorm, nor'easters tend to linger, often bringing a full day or more of heavy rain, high winds, and rough surf. They're most common in fall and winter, and because Long Island sits right along the coast, we tend to feel their effects more than inland areas: think downed trees, power outages, and - especially along the South Shore - coastal and tidal flooding.

Your go-to supplies for a big storm. Batteries, water (for 3 days), shelf stable foods, and more.

How to Prepare: 8 Things to Do Before a Storm Hits

1. Charge your devices and gather flashlights Power outages are one of the most common nor'easter impacts. Charge phones, laptops, and battery packs now, and make sure flashlights (not just candles) are easy to find.

2. Stock up on essentials Have at least three days of water, non-perishable food, medications, and pet supplies on hand in case roads are impassable or stores lose power.

3. Secure loose outdoor items Patio furniture, grills, trash cans, and decorations can become dangerous projectiles in high winds. Bring them inside or tie them down.

4. Clear gutters and drains Leaf-clogged gutters and storm drains are a major cause of flash flooding in the fall. A quick cleanout now can prevent water from backing up into your home.

5. Check on your sump pump If you have one, test it before the storm and consider a battery backup — sump pumps often fail right when you need them most, during a power outage.

6. Move vehicles and valuables to higher ground If you're in a flood-prone area, especially along the South Shore, move cars away from low-lying streets and bring anything stored in a garage or basement up off the floor.

7. Know your evacuation zone If you live along the coast, check your FEMA flood zone or Suffolk County evacuation zone in advance, and know your route if local officials issue an evacuation order.

8. Avoid driving through flooded roads Just six inches of moving water can sweep a car off the road. If you see a flooded street, turn around — don't risk it.

For South Shore Homeowners: Flooding-Specific Tips

Many of our clients live along Long Island's South Shore, where storm surge and tidal flooding are a real concern during a nor'easter. A few extra steps for flood-prone properties: 

• Use sandbags or flood barriers at doors and low points of entry if flooding is expected.

• Elevate anything stored in a basement or garage — flood water can rise quickly, even a few inches can cause real damage.

• Turn off electricity to flood-prone areas if water intrusion seems likely, and never enter a flooded basement without confirming the power is off.

• Document your home now with photos or video, before the storm, in case you need to file an insurance claim afterward.

• Review your flood insurance policy — standard homeowners insurance typically does not cover flood damage, so it's worth knowing what is and isn't covered before a storm hits.

For Everyone: High Wind Precautions

Down trees tend to cause the most damage. Prepare for outages by taking these precautions below.

• Trim or note any overhanging tree branches near your home or driveway.

• Park vehicles away from large trees when possible.

• Close storm shutters or board up windows if you're in a particularly exposed area.

• Have a battery-powered radio or weather app ready in case cell service is disrupted.

The Bottom Line

Nor'easters are simply part of life on Long Island, but a little preparation goes a long way. Taking an hour before the storm to secure your property, check your flood readiness, and stock a few essentials can make a real difference if this storm brings the impacts forecasters are expecting.
