NOAA lowered its 2026 Atlantic hurricane season outlook on Thursday, Aug. 6, 2026, raising the odds of a below-normal season to 75% from 55% in May. For Tennessee households, that headline is close to meaningless — and the reason is worth two minutes of your time.
What did NOAA actually change?
The agency trimmed every range in its updated outlook, citing the growing influence of El Nino and the stronger upper-level winds it creates across the tropical Atlantic.
| 2026 Atlantic season outlook | August update | May outlook |
|---|---|---|
| Named storms | 7-13 | 8-14 |
| Hurricanes | 2-6 | 3-6 |
| Major hurricanes | 0-2 | 1-3 |
| Odds of a below-normal season | 75% | 55% |
| Odds of a near-normal season | 20% | — |
| Odds of an above-normal season | 5% | — |
| Named storms so far | 2 (Arthur, Bertha) | — |
| 1991-2020 seasonal average | 14 named / 7 hurricanes / 3 major | — |
| Climatological peak | around Sept. 10 | — |
Does a quieter season mean lower risk in Tennessee?
No. A seasonal outlook forecasts basin activity, not your local risk — NOAA says so directly. A below-average season can still produce one devastating landfalling storm, and for Tennessee the damage almost never arrives as a hurricane. It arrives as heavy rain, flash flooding and tornadoes hundreds of miles inland from a tropical system's remnants. Activity historically ramps up fast in the second half of August.
Which of my policies responds to a remnant storm?
It depends on how the water reaches your house, and that distinction decides claims every year:
- Wind and wind-driven rain — covered under most standard Tennessee homeowners policies, per the Tennessee Department of Commerce and Insurance.
- Rising water and flash flooding — excluded. That requires separate flood coverage, and a new NFIP policy typically carries a 30-day waiting period.
- Interior water with no wind opening — often denied. If wind opens your roof, the resulting water is typically covered; if water simply blew in, it often is not.
- Fallen trees that did not hit the house — frequently your expense without a debris-removal endorsement.
- Detached structures — usually Coverage B, commonly about 10% of the dwelling limit for all detached structures combined.
What to do in the next three weeks
- Check your wind/hail deductible. Many Tennessee policies now carry a percentage deductible, not a flat dollar amount.
- Decide on flood coverage now. With the peak around Sept. 10, a 30-day waiting period means the decision window is already closing.
- Confirm replacement cost on the dwelling and the roof. Age-based roof schedules are common now.
- Photograph your interior. Ten minutes today settles scope arguments after a loss.
Peak season is ahead of us, not behind. A forecast that says fewer storms says nothing about whether one of them tracks up the Tennessee Valley.
