A Quiet Hurricane Season Is the Worst Time to Drop Flood Coverage

Nobody in Maryland, DC or Northern Virginia has had a tropical scare this year. Not one. That is not a feeling, it is the record: no Atlantic storm in 2026 has affected our area at all.

Which is exactly why this is the month people quietly let flood coverage lapse.

Just how quiet has it been

NOAA called for a below normal season back in May, then revised further downward in August. Even against that lowered bar, 2026 has undershot.

As of late September there have been six named storms and zero hurricanes. On September 11 the season passed the satellite era record for the latest first hurricane. Accumulated cyclone energy, the measure forecasters use for a season total, sat around four and a half units in mid September, against a normal season median closer to one hundred. Every US landfall this year has been a tropical storm, all of them on the Gulf Coast.

So the instinct is understandable. Nothing happened. Why keep paying.

The most expensive storm of the year was not a hurricane

Tropical Storm Arthur came ashore near Galveston in June with 45 mile per hour winds. It was never close to hurricane strength. It caused more than a billion dollars in losses and four deaths, and dropped roughly thirty inches of rain on Louisiana.

That is the whole argument in one storm. Wind speed is what makes the news. Water is what wrecks houses. A slow, soaking, unremarkable system that parks over a watershed will do more damage to a basement in Rockville than a fast moving hurricane that stays offshore.

And in our region, most flooding never involves a tropical system at all. It comes from a stalled summer thunderstorm over a creek, a saturated spring, or an afternoon that drops three inches in an hour onto ground that cannot take it.

October and November are not a formality

The National Hurricane Center puts the peak of the Atlantic season at September 10 and describes most activity as occurring between mid August and mid October. The season runs through November 30.

Its own climatology is more pointed than that summary suggests. In an average season the fifth hurricane forms around September 28, the sixth around October 15, and the seventh around November 15. The third major hurricane of a typical year does not form until the end of October. Roughly one named storm in five still forms after October 1.

This year, with zero hurricanes on the board through the climatological peak, the season has produced less than a normal year rather than finished early.

The waiting period is the part that punishes procrastination

A new National Flood Insurance Program policy generally takes effect on the thirtieth day after you apply and pay. Buy on October 1 and you are covered starting October 31.

There are only a few exceptions, and FEMA lists them narrowly:

• No wait when you buy flood insurance in connection with making, increasing, extending or renewing a mortgage.
• No wait when you change coverage at renewal on an existing policy.
• A one day wait if your property has just been mapped into a high risk zone and you buy within twelve months of the map change.
• A one day wait where flooding is caused or worsened by a wildfire on federal land and you buy within 60 days of containment.

Outside those situations, the thirty days run. There is no way to shorten them once a storm is in the forecast, which is the entire design of the rule. Private flood policies set their own effective dates and the wait is often shorter, but it varies by carrier and the coverage is not always identical. That is worth a conversation rather than an assumption.

Worth noting on timing: Montgomery County, including Gaithersburg and Rockville, has preliminary new flood maps working through the FEMA process, with the appeal period already closed. When revised maps take effect, the one day exception above becomes available to newly mapped properties for a limited window. If your property is affected, that is a window you do not want to miss.

Two things most homeowners get wrong about flood

Your homeowners policy does not cover it. FEMA states plainly that most homeowners and renters insurance does not cover flood damage. This is not a gap in your particular policy or something a good agent could have negotiated. It is how the product is built, everywhere, for everyone.

You do not have to be in a flood zone. FEMA reports that over the past ten years nearly one third of NFIP claims have come from outside high risk zones. FEMA also notes that 99 percent of US counties have experienced a flood in the past twenty years. Being outside the mapped floodplain lowers your premium. It does not lower the water.

It is also worth knowing what a flood policy does and does not reach. The NFIP definition requires inundation of two or more acres or of two or more properties, which is why a single flooded basement from a clogged downspout is neither a flood claim nor a homeowners claim. And the standard flood policy excludes personal property kept in basements, most property outside the building such as decks, fences, landscaping and pools, and temporary housing or additional living expenses. Residential building coverage tops out at 250,000 dollars with 100,000 for contents.

Federal disaster aid is not a substitute, and Maryland has the receipts

People skip flood coverage on the assumption that a bad enough event brings federal help. Sometimes it does. It is not a promise.

Western Maryland saw serious flooding in the spring of 2025, with damage reported in the tens of millions of dollars. The request for federal disaster aid was denied. FEMA says as much on its own site: federal disaster assistance is not guaranteed, and it is only available with a presidential disaster declaration.

An insurance policy is a contract. Disaster aid is a decision somebody else makes later.

One deadline actually on the calendar

The NFIP is currently authorized, but only through December 11, 2026. That extension, passed in early September, is the thirty sixth short term reauthorization since 2017, and the program did lapse briefly during the shutdown in the fall of 2025.

During a lapse the program cannot issue new or renewal policies. Existing policies stay in force to their expiration date and claims continue to be paid while FEMA has funds, so this is not a reason to panic if you already have coverage. It is a reason not to leave a new purchase sitting on your to do list into December, when a thirty day waiting period and an authorization deadline could collide.

What to do this month

• If you carry flood coverage and were thinking of dropping it at renewal, wait until December 1 and decide then. You will have given up nothing.
• If you do not carry it, price it now rather than in the spring. The thirty days have to run sometime, and running them during the quiet part of the year is the cheapest version of that decision.
• Check whether your property sits in the Montgomery County preliminary map changes.
• Ask about contents coverage separately, and about what the basement exclusion means for how you actually use your lower level.
• If a lender is involved in a purchase or refinance, remember the waiting period does not apply, which sometimes makes the timing easier than people expect.

We write flood coverage across Maryland, Washington DC and Northern Virginia, and we would rather have this conversation in October than in the middle of a June storm when nothing can be done. If you want to know what it would actually cost for your address, ask us and we will find out.

Frequently Asked Questions

How long does it take for a new flood policy to take effect?
Generally 30 days from the date you apply and pay. A policy bought on October 1 takes effect October 31. The main exceptions are a purchase tied to making, increasing, extending or renewing a mortgage, a change at renewal, a property newly mapped into a high risk zone, and certain post wildfire situations.

Do I need flood insurance if I am not in a flood zone?
Many people outside high risk zones do buy it, and FEMA reports that nearly one third of flood claims over the past ten years came from outside those zones. Being outside the mapped floodplain generally means a lower premium rather than no exposure.

Does homeowners insurance cover any flooding?
Not flooding as the flood program defines it. A homeowners policy may respond to certain water losses that originate inside the home, such as a burst pipe, and some policies offer a separate water backup endorsement. Rising water from outside the home is a flood loss and needs a flood policy.

Is the hurricane season really over in October?
No. The Atlantic season runs through November 30. National Hurricane Center climatology shows the average season producing its sixth hurricane around October 15 and its seventh around November 15, and roughly one named storm in five forms after October 1.

What does a flood policy not cover?
A standard flood policy excludes personal property kept in a basement, most property outside the building such as decks, fences, landscaping and swimming pools, and temporary housing or additional living expenses. Residential building coverage is capped at 250,000 dollars with 100,000 for contents.
