When a client’s address lands in a newly identified tornado risk zone, the first thing you should do is pull an updated weather‑risk assessment and ask the underwriter whether a tornado add‑on or a premium adjustment is warranted. The shift in tornado activity isn’t a distant headline – it’s a concrete change that can alter the loss profile of a policy overnight.
What I'm watching for in submissions is whether agents are proactively checking tornado risk zones before renewals. When this hits agent desks, the question I'd ask is: Has your client's address been rechecked against the latest tornado risk map?
Why the risk is moving
A recent analysis reported by Insurance Journal indicates that tornado activity, historically concentrated in the central U.S. "Tornado Alley", is shifting northward into the Midwest. The study highlights increased frequency of EF‑2+ tornadoes in states including Ohio, Indiana, Kentucky, and parts of Illinois, a trend projected to persist with changing climate. This expansion raises exposure for businesses in these regions, particularly those with open floor plans or roof-mounted equipment.
What this means for your book
For agents, the practical implication is that a policy that once carried a modest tornado rider may now be under‑priced. If a client’s location has moved into a newly flagged risk zone, loss costs for tornado coverage can increase significantly, depending on the exposure profile. In addition, many carriers now require a formal weather‑risk assessment for policies in high‑risk zones, and some have begun to adjust base premiums for all policies in those states.
Concrete steps to take
- Verify the client’s address. Confirm the exact city and ZIP code, and cross‑check it against the latest tornado risk map released by the National Weather Service and the modeler’s report.
- Request a weather‑risk assessment. Ask the underwriter to provide a formal assessment that includes the frequency and intensity of tornadoes in the area, as well as any recent changes in local building codes that might mitigate risk.
- Consider a tornado add‑on. If the assessment shows a significant increase in risk, discuss adding a tornado rider or a dedicated tornado policy. Many carriers offer a "tornado add‑on" that covers wind damage and debris, which can be priced separately from the base policy.
- Adjust the premium. If the client is already carrying a tornado rider, the underwriter may recommend a premium increase to reflect the new risk profile. Use the assessment data to justify the adjustment to the client and to the carrier.
- Document the change. Update the policy file with the new assessment, the decision to add or adjust coverage, and any correspondence with the underwriter. This documentation will be critical if the client files a claim or if the carrier audits the policy later.
Why the medical price growth slowdown matters too
The NCCI's latest data indicates that medical price growth slowed to 1.0% in June, suggesting that claim costs are not rising as quickly as before. However, the increased tornado exposure can still elevate overall loss costs, so agents should consider both trends when forecasting renewals.
What this means for your placements
In practice, you’ll need to add a new step to your renewal workflow: a quick check of the client’s location against the latest tornado risk map. If the client is in a newly flagged zone, you’ll pull a weather‑risk assessment, discuss coverage options with the underwriter, and adjust the premium or add a rider as needed. By doing this proactively, you protect your clients from under‑insurance and position yourself as a risk‑aware advisor who keeps pace with changing climate realities.
