DMV Storm-Season Prep: A Homeowner & Renter Checklist

There’s a version of storm preparedness that only happens when a hurricane’s name is already on the news — the rush to the hardware store, the empty bottled-water shelves. The better version happens quietly, before the season, and it’s especially worth doing in the DMV because the region floods in so many different ways. A July flash flood, a September tropical remnant, an October king tide, a February nor’easter — each calls for a slightly different readiness, and all of them reward a household that prepared in the calm.

This is a practical storm-season checklist for DC, Maryland, and Virginia residents, built around the region’s actual flood calendar and grounded in official guidance from FEMA’s Ready.gov and the National Weather Service.

Step 1 — Know your risk

Preparation starts with knowing what you’re preparing for. Two questions matter most:

• What’s your flood zone? Look up your address at the FEMA Flood Map Service Center. Our guide to DMV flood zones and maps explains the codes.
• What’s your neighborhood’s flood mechanism? A tidal-Potomac home in Old Town Alexandria faces different timing and warning than a flash-flood-prone block near Cameron Run or a combined-sewer neighborhood in DC. Our DMV flood geography overview maps the three patterns.

Knowing your mechanism tells you how much warning to expect. Tidal flooding comes with hours of tide and surge forecasts; flash flooding may come with minutes.

Step 2 — Prepare your home

Most of the highest-value home prep is cheap and can be done in an afternoon:

• Clear gutters, downspouts, and yard drains so water moves away from the foundation, not toward it.
• Check grading — soil should slope away from the house. Even a small reverse slope channels water to the basement wall.
• Test your sump pump before the season, and consider a battery backup — DMV power outages and heavy rain tend to arrive together. See why DMV basements flood.
• Install or check a backwater valve if you’re in an older combined-sewer neighborhood prone to backups.
• Move valuables and important systems up — get irreplaceable items off the basement floor, and elevate or protect mechanicals where you can.
• Know your shutoffs — locate the main water, gas, and electrical shutoffs and learn how to operate them safely.

For renters, the home-prep list is shorter but real: know where water has come in before, keep valuables off basement and ground floors, and confirm with your landlord how drainage and sump systems are maintained.

Step 3 — Build a kit and a plan

FEMA’s Build a Kit guidance is the standard. A basic household kit includes:

• Water — one gallon per person per day for several days.
• Non-perishable food for several days, plus a manual can opener.
• Flashlight and batteries, and a battery or hand-crank radio for alerts if the power and cell network fail.
• Medications and a first-aid kit.
• Copies of key documents — insurance policy, IDs, deed or lease — in a waterproof container or secure cloud storage.
• Chargers and a backup battery for phones.

Then make a household plan: where you’ll go if you need to leave, how everyone will communicate if separated, and an evacuation route that avoids the low roads and underpasses that flood first.

Step 4 — Sign up for alerts

The warning only helps if it reaches you. Set this up before you need it:

Keep Wireless Emergency Alerts enabled on your phone — these push flash-flood and other urgent warnings automatically — and don’t rely on a single channel.

Step 5 — Review insurance early

This step has a deadline built in. Standard homeowners insurance does not cover flood damage, and a flood policy through the National Flood Insurance Program typically carries a 30-day waiting period. That means you cannot wait for the forecast — coverage bought as a storm approaches won’t be in force when it arrives. Before the season:

• Confirm whether you have flood coverage, separate from your homeowners or renters policy.
• Understand what your homeowners policy does cover (often sudden internal water damage like a burst pipe) versus what it excludes (rising surface water). Our flood vs. water damage explainer covers the distinction.
• Document your belongings now — photos and a simple inventory make any future claim far easier.

Step 6 — Know what the alerts mean

When the watches and warnings start, the wording tells you how urgently to act:

• Flood Watch — conditions are favorable for flooding. Review your plan, move valuables up, charge devices, and stay alert.
• Flood Warning — flooding is imminent or occurring. Act on your plan; be ready to move to higher ground.
• Flash Flood Warning — rapidly rising water, often with little lead time. Move to higher ground immediately and never enter floodwater.
• Coastal Flood Advisory / Warning — tidal flooding along the Potomac; relevant to Old Town Alexandria and the DC waterfront.

The NWS Baltimore/Washington office is the authoritative source for all of these during an event, and our DMV storm season guide explains the regional patterns behind them.

Renters: a focused checklist

Renters often assume storm prep is the landlord’s job. Some of it is — but the parts that protect you are yours. The renter’s version of this checklist is short and worth doing the week the forecast turns warm:

• Get renters insurance with the right coverage. A standard renters policy covers your belongings against many perils but typically excludes flood, just like a homeowners policy. If you’re in or near a mapped flood area — a garden-level unit near Cameron Run, a basement apartment in an older DC row house — ask specifically about flood coverage through the NFIP, which is available to renters for contents.
• Learn your unit’s flood history. Ask the landlord or neighbors whether water has come in before, and where. A unit that flooded once will likely flood again under the same conditions.
• Keep valuables off the floor in basement and ground-level units, and store irreplaceable documents high or in the cloud.
• Know the building’s drainage. Find out whether there’s a sump pump, who maintains it, and what happens during a power outage.
• Have your own kit and exit plan, independent of the building’s — see Build a Kit.

The lesson the DMV teaches repeatedly is that flood water doesn’t check the deed. A renter in a low unit can lose as much as the owner upstairs, and the coverage that protects renters is the part most often overlooked.

After the water recedes

If your home does take on water, switch to recovery mode safely: address electrical and contamination hazards before reentering, document everything for insurance before you move or discard anything, and dry thoroughly and quickly — mold can begin within a day or two. Our DMV water damage guide walks through the steps, drawing on EPA and CDC guidance.

The short version

Storm-season prep in the DMV comes down to six moves you can make before the first watch is issued: know your risk, prepare your home, build a kit and plan, sign up for alerts, review insurance, and learn what the warnings mean. None of it requires a forecast — which is exactly why the prepared household is the one that did it early. Pair this checklist with your flood zone, your neighborhood’s flood pattern, and your jurisdiction’s official resources, and let the National Weather Service be your authority when the sky turns.
