Vermont Storm Dates: A Homeowner's Lookup Guide

By StormAuditor Editorial Team · Published 2026-09-28 · Updated 2026-09-28

Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.

Damage-threshold ranges in this article are general guidance synthesized from industry and federal research — IBHS building-performance research, NWS severe criteria, and product standards such as UL 2218 (hail impact resistance) and ASTM D3161/D7158 (shingle wind ratings). Actual performance depends on product rating, age, installation quality, exposure, and impact characteristics — thresholds describe when damage becomes possible, not when it occurs.

A step-by-step way to look up Vermont storm dates at your home, grounded in 565 events in StormAuditor's public-record tally for the 12 months through September 24, 2026.

On July 1, 2026, StormAuditor's public-record tally logged 125 Vermont storm events in a single day, all hail and wind. That was the busiest Vermont storm date in the 12 months through September 24, 2026, with more than twice the entries of the next-busiest day. Dates like that one are easy to spot after the fact. The harder job for a homeowner is matching a storm date to one house.

This guide walks through how to look up Vermont storm dates yourself, using the state's actual record for that window. Vermont's numbers are small, which makes each entry easier to read and each gap easier to misread.

Vermont's storm record, in small numbers

In the 12 months through September 24, 2026, StormAuditor's public-record tally counts 565 storm events in Vermont, with all 14 counties represented. Wind accounts for 303 of them, hail for 224, flood for 31, and tornado for 7.

Most of those entries are warnings. In the same window, 477 sit at the warning level, 42 at the "reported" level, 32 at the "observed" level, and 14 come from official backfill. A warning covers an area and a time window. A home inside a warning was under that warning; it did not necessarily see the storm's strongest wind or largest hail.

NCEI's Storm Events Database adds a second, slower view. In NCEI records available through June 2026, Vermont has entries for only two months: 7 in April 2026 and 23 in June 2026. Months without entries are not evidence of calm weather. NCEI publishes with a lag of months.

Step by step: looking up a Vermont storm date

Step 1: Bracket the window

Start with the earliest and latest dates the damage could plausibly date to. If you noticed a leak in May, the weather behind it may date to April or earlier. Write the bracket down before opening any tool, so the search is not steered by whichever storm you remember best.

Step 2: Compare your bracket with the busiest dates

The ten busiest Vermont days in the 12 months through September 24, 2026 were:

1. July 1, 2026: 125 events (hail, wind)

2. August 10, 2026: 55 (flood, hail, tornado, wind)

3. June 18, 2026: 42 (flood, hail, tornado, wind)

4. December 19, 2025: 41 (wind)

5. July 15, 2026: 26 (hail, wind)

6. August 12, 2026: 25 (hail, wind)

7. April 16, 2026: 24 (hail, tornado, wind)

8. June 6, 2026: 18 (hail, wind)

9. April 14, 2026: 17 (hail, wind)

10. July 16, 2026: 17 (hail, wind)

A date on this list is a strong starting point. A date not on it is not ruled out; a single cell can hit one town on an otherwise quiet day.

Step 3: Check county context

County totals show whether your area was part of the pattern. In the 12 months through September 24, 2026, Chittenden County led Vermont with 56 events in StormAuditor's tally. Addison followed at 54, Bennington at 53, and Rutland at 52. Lamoille and Washington logged 43 each, and Orange and Windsor 42 each.

Step 4: Record numbers, with their type

Write down the specific values for your date and label each one: a measured report, a radar estimate, or an analysis estimate. The next section explains why that label matters.

Measured, radar, and analysis values are not the same

Hail

The largest ground hail report in the 12 months through September 24, 2026 was 1.75 inches, near Williamstown on April 16, 2026. The statewide radar maximum that day (NOAA MRMS MESH) was 1.60 inches, and 2 ground hail reports came in. Other notable ground reports were 1.5 inches near Fair Haven on August 13, 2026 and 1.25 inches at South Hero on August 8, 2026.

Radar also shows larger values on days without ground support. April 25, 2026 carries a 3.64-inch value, a radar estimate with no ground reports that day. Radar can overestimate hail in very high reflectivity cores and underestimate wet hail, so a value like that is a reason to look closer, not a stone size.

Wind

The strongest measured gust report was 106 mph at Mount Mansfield on December 19, 2025, from a mesonet sensor on an exposed summit. Lower-elevation reports that same day included 73 mph at South Lincoln and 67 mph near Pleasant Valley.

NOAA's gridded analysis is an estimate on a grid, not a sensor reading. Its highest Vermont values were an estimated 77 mph on April 5, 2026, when a measured gust report reached 59 mph, and an estimated 74 mph on March 16, 2026, when a measured report reached 61 mph. Those measured values clear the NWS severe-gust criterion of 58 mph.

Where StormAuditor fits

StormAuditor's Vermont storm data page holds the statewide view. For a claim-oriented workflow, the date-of-loss weather research page explains how storm dates are researched and documented.

At the property level, Address Lookup shows NWS warnings, storm reports, and NOAA station observations for your address, free with an account. The Free Report Snapshot gives a yes or no on whether estimated wind reached StormAuditor's 45 mph screening level, or estimated hail its 0.75-inch screening level, at the address in the window checked. Those screening levels sit below the NWS severe criteria of 58 mph and 1.00 inch. For a dated list, the Weather Report shows every qualifying storm date with estimated peak gust and estimated maximum hail size from SAWE-2 and SAHE-2, plus the nearest measured evidence with distances.

Limitations

• Every figure here is an estimate of the public weather record, not a measurement at your home or a finding about damage.
• Vermont's counts are small, so a single storm day can move a county's ranking.
• Radar hail values can differ from what reached the ground, especially in valley and mountain terrain.
• Summit sensors like Mount Mansfield describe exposed sites. Stations are spaced apart, and peak gusts between them can exceed reported values.
• NCEI data lags by months; its figures here cover only records available through June 2026.
• For damage questions, a qualified inspector is the right source. See the limitations page.
