Audits
Seattle has frequent rain but less yearly rainfall than many U.S. cities.
Version 2. FactHub's auditors are automated reviewers, separate from the process that writes articles. Each checks a fixed, published list of things and grades the results with its own published rule. They can be wrong; an audit is not a human expert review. All auditors

Pass Title matches the evidence
Title says Seattle has frequent rain but less yearly rainfall than many cities, which matches the 39.34-inch total and the Misleading finding.
-
Pass No obvious contradictions
Finding, answer, and conclusion consistently say Seattle is not among the rainiest by annual precipitation; the monthly figures sum to the stated totals.
-
Pass Plausible justification
Conclusion explains the rating from station totals and wet-day frequency, which a reader would accept.
-
Pass Sources are relevant
NOAA normals, NOAA documentation, NWS Seattle summaries, and NPS regional guidance are all on topic.
-
Pass Common questions answered
Five common questions each have a response that addresses the objection.

Concern (minor) Sourcing is strong and transparent
Anchor the 156 measurable-precipitation days to a specific 1991–2020 table; the cited Comparative Climatic Data page says its normals tables are 1981–2010.
Sources are primary federal (NOAA NCEI, NWS, NPS) - strong. But the wet-day evidence says 'NOAA and National Weather Service climate summaries put Seattle near 156 days' with years 1991-2020, while the cited Comparative Climatic Data page describes itself as 'CCD-2018' and states 'The tables below contain the 1981–2010 Climate Normals data'; its observed-data days-with-precipitation tables are period-of-record means. The NWS source is a generic NOWData portal with the note 'The above data are unofficial'. A reader cannot tell which table yields 156 or for which period. The station normals cite a Quick Access landing page rather than station-level anchors, though station IDs mitigate this. Minor because the figure is plausible and not the basis of the rating. Confidence: Medium.

Concern (material) Context is complete
Add a wet-day frequency comparison with other major cities (e.g., Buffalo, Rochester, Pittsburgh, Portland) to show whether Seattle ranks among the rainiest by that measure.
The article itself says 'Rainiest can mean greatest annual precipitation, most days with measurable precipitation... those measures produce different rankings', yet it ranks only by annual volume. For frequency it gives only Seattle's figure and asserts it is 'frequent compared with many high-total cities' without any comparison numbers. The article does not address whether Seattle ranks near the top of major U.S. cities by days with measurable precipitation (cities such as Buffalo, Rochester, Cleveland, Pittsburgh, and Portland, Oregon are commonly cited alongside it). Many people who repeat the claim mean frequency. If Seattle is among the leaders by that measure, the claim is partly true and the Misleading label and 'not one of the nation's rainiest' conclusion would read differently (Mixed may fit). This omission can change the reader's impression. Rests partly on my own knowledge, so Material, not Fail. Confidence: Medium.

Concern (minor) Framing is fair and neutral
Revise the seoTitle "The Data Say No" to reflect that the answer depends on the measure, since the article concedes Seattle is frequently wet.
The body is fair and balanced: the title 'Seattle has frequent rain but less yearly rainfall than many U.S. cities' and conclusion 'Seattle's rainy reputation is understandable but imprecise' represent both sides, and objections are answered respectfully. However, the seoTitle 'Is Seattle One of America's Rainiest Cities? The Data Say No' gives an unqualified no, emphasizing the volume measure over the frequency measure the article concedes. Minor: uneven emphasis in one field. Confidence: High.

Concern (minor) Uncertainty is stated
Lower confidence to Moderate or align it with the conclusion, which says confidence in broad rankings is only moderate.
Limitations are well stated (airport vs city, no official definition of 'major city', rounding). But the confidence field is 'High' while the conclusion says 'Confidence: High for the station comparisons; moderate for broad rankings because major city and rainiest have no single official definition.' The claim being rated is a broad ranking, so by the article's own reasoning confidence in the verdict is a step high. Confidence: High.

Pass Central claims are accurate
Key claims: (1) Sea-Tac 1991-2020 normal is 39.34 in - Unverifiable from snapshots (Quick Access returned no data) but consistent with the widely published Sea-Tac normal; Mostly True/True. (2) Miami, New Orleans, Houston, Atlanta, NYC Central Park, Boston all exceed Sea-Tac - exact decimals Unverifiable from snapshots; the direction (Seattle's annual total is well below these Gulf/East Coast cities) is a well-established, uncontested fact; True. (3) About 156 days with >=0.01 inch - Unverifiable from the cited pages; plausible for Sea-Tac; Mostly True. (4) Wet season Oct-Mar, dry July-Aug - supported by the NOAA memo abstract: 'a pronounced though not sharply defined rainy season, and considerable cloudiness, particularly during the winter months'; True. (5) Olympic Mountains create sharp precipitation contrasts - supported by NPS: 'Annual precipitation ranges from 100-170 inches... along the coast' vs Port Angeles '25-30 inches'; True. (6) Normals are 1991-2020, recommended period - supported by NOAA product page ('We recommend using the current 1991-2020 release'); True. No central claim is Mixed or worse. Peripheral note: the image alt text says 'cloudy gray sky' while the Commons page categorizes it as 'Clouds and blue sky'; I have not seen the image, so I do not report it. Confidence: Medium, because exact station figures could not be checked against source text.
-
Pass Claims are supported and labeled
Every central claim cites evidence: the annual totals cite NOAA Quick Access and documentation with named station IDs (USW00024233 etc.) and a reproducible method ('Summed the twelve monthly precipitation normals'). Inferences are labeled as such: 'Frequency therefore supports calling Seattle often wet, but not highest in annual volume.' Opinion is not presented as fact. The sourcing-quality check covers the weaker anchor for the 156-day figure. Confidence: High.
Coverage: Read all eight cited sources via get_source_snapshot (live copies; none archived). noaa-normals-documentation is a PDF the server cannot read (unavailable). noaa-normals-quick-access returned only a JavaScript shell with no station values, and nws-seattle-climate returned only the NOWData tool interface, so none of the station figures (39.34, 67.41, 63.35, 51.84, 50.43, 49.52, 43.59 inches; 156 wet days; monthly values) could be checked against source text. noaa-normals-product, noaa-comparative-climate, noaa-seattle-climate-memo (abstract/catalog page only, not the 1998 PDF), nps-olympic-weather, and the Wikimedia Commons page were read in full. Article summary: Seattle (Sea-Tac) gets about 39 inches of precipitation a year under NOAA 1991-2020 normals, less than six named major-city stations, but rain falls on many days in a long cool season, so the claim is rated Misleading.
Skeptic
C: The rating is defensible, but the article overstates its case, rates a somewhat different claim, or skips its strongest challenge.
- Confidence matches the evidence

Concern (minor) Confidence matches the evidence
Lower confidence to Moderate: the conclusion itself says confidence in broad rankings is moderate, and the seoTitle's flat "No" overstates the finding.
Confidence field is 'High', but the conclusion says 'Confidence: High for the station comparisons; moderate for broad rankings because major city and rainiest have no single official definition.' The claim being rated is a broad ranking, so by the article's own reasoning Moderate fits. The seoTitle 'The Data Say No' is also stronger than the evidence, which concedes the frequency dimension. The title proper is well calibrated. Limitations are stated well (airport vs neighborhoods, wet-day threshold, rounding). I would give Moderate. One step high: Minor. Confidence: High.

Concern (material) Strongest objections answered
Answer whether Seattle ranks among the rainiest major cities by wet-day frequency, with a cross-city comparison of days with at least 0.01 inch.
The strongest objection is that 'rainiest' in the popular claim means how often it rains, not inches per year. The article lists this ('It rains all the time in Seattle...') but answers by assertion: 'Frequent rain and large annual totals are different measurements... several major-city stations accumulate much more water.' That restates the volume result rather than testing the frequency version. Evidence e3 gives only Seattle's ~156 days and says this is 'frequent compared with many high-total cities' with no comparison figures. The article does not address whether Seattle ranks at or near the top of major U.S. cities by measurable-precipitation days (it is commonly grouped with cities such as Buffalo, Rochester, Cleveland, Pittsburgh, and Portland, Oregon). If it does, the claim is true under that reading and Mixed may be the better label. Other objections (airport station, hurricanes, grayness, nearby wetter places) are answered fairly. Rests partly on outside knowledge, so Material, not Fail. Confidence: Medium.
About conclusion, evidence:wet-day-frequency The finding

Concern (minor) Evidence is independent
Note that evidence e1, e2, and e4 all draw on the same NOAA Quick Access station normals; the volume comparison rests on one dataset.
e1 (seattle-noaa-normal), e2 (major-city-comparison), and e4 (seasonal-regional-context) all cite noaa-normals-quick-access and all derive from the NCEI 1991-2020 station normals. e3 uses NOAA Comparative Climatic Data and NWS summaries, which come from the same station observation network, and e4 adds an NPS topographic explanation. Context nonetheless says the conclusion is strong because 'NOAA station normals, occurrence statistics, regional climate descriptions, and multiple city comparisons converge.' The volume finding is single-dataset; that dataset is authoritative and the claim is a measurement question, so independent support for the reputation side (frequency, topography) remains. Minor overlap rather than collapse to one source. Confidence: High.

Pass Rates the real claim
Claim: 'Seattle is one of the rainiest major cities in the United States.' This is how it circulates. The article does not strawman it: method step 1 'Defined rainiest separately as annual precipitation amount, measurable-precipitation frequency, and seasonal persistence', and the conclusion stays within scope ('not one of the nation's rainiest major cities by annual precipitation'; airport station vs city noted). The gap in how the frequency reading is tested is handled under strongest-objection. Confidence: High.
-
Pass Rating follows from the evidence
Before reading the label I would rate this Misleading or Mixed: evidence e1/e2 show Sea-Tac's 39.34 in is below six named major-city stations (67.41 to 43.59), while e3 shows ~156 wet days that make the 'rains a lot' impression understandable. Taking the evidence as stated (no cross-city frequency ranking is presented), Misleading fits: the claim's common implication of large rainfall is not borne out, though there is a basis for the impression. The answer ('less than Miami or New York, but rain falls on many days') agrees with the label. Confidence: Medium-High.
Coverage: Read the full article payload (claim, finding, answer, confidence, summary, keyPoints, context, conclusion, four evidence items with limitations, five objections, eight method steps, sources). Per the Skeptic's division of labor, no source snapshots were read for this run and evidence was taken as stated.

Concern (minor) Verdict fields agree and stand alone
Align the conclusion's "High for station comparisons; moderate for broad rankings" with the confidence field, or change the field to match.
Read as: FactHub rates the claim 'Seattle is one of the rainiest major cities in the United States.' Misleading (High confidence): 'Seattle gets about 39 inches a year, less than Miami or New York, but rain falls on many days.' The claim is worded as it circulates and the answer stands alone. Title, answer, summary, and conclusion agree in direction. However, the conclusion ends 'Confidence: High for the station comparisons; moderate for broad rankings', which does not match the single 'High' confidence field in the verdict statement. Rule: the verdict fields must express the same conclusion. The direction does not conflict, so Minor.

Concern (minor) Each section does its job
Remove the hand-written "Independence note" from editorialNote and the analytic last sentence of context, and trim the summary to one sentence.
Rule: the independence note is generated by the page and the author must not write one; editorialNote contains 'Independence note: the evidence represents one country, multiple stations, three federal scientific or land-management sources, several measurement types, and records summarized over three decades.' Rule: context is essential framing only, not analysis; context ends 'The conclusion is strong because NOAA station normals, occurrence statistics, regional climate descriptions, and multiple city comparisons converge.' Rule: summary is one sentence naming the strongest evidence; the summary is three sentences listing all six city figures. The conclusion does synthesize (wet days, seasonality, definitional limits) and the editorialNote states scope, caveats, and review status ('No external meteorologist review has been recorded'), so these are Minor misplacements.

Concern (minor) Consistent house style
Delete the stray "Weather | Fact check." prefix from context and spell out NOAA (National Oceanic and Atmospheric Administration) at first use.
Rule: no leftover drafting text or typos. Context begins 'Weather | Fact check.', a stray label/breadcrumb rather than a sentence of framing (Minor, not a note to editors or placeholder). Rule: an abbreviation is spelled out at first use; the summary opens with 'NOAA's standard 1991–2020 climate normals' and NOAA is never spelled out in reader-facing text (it appears expanded only in evidence institution metadata). Otherwise consistent: inches throughout, figures match across summary, keyPoints, evidence, and conclusion (39.34, 156, 70 percent), en-dash date ranges, American spelling.
About conclusion The finding
-
Pass Title states the finding
Title: 'Seattle has frequent rain but less yearly rainfall than many U.S. cities.' It names the subject, states the finding in positive form, does not repeat the myth, and resolves the claim for a title-only reader (rule: lead with what is true; resolve the claim). seoTitle 'Is Seattle One of America's Rainiest Cities? The Data Say No' uses search wording and states a finding, which the seoTitle rule permits. Whether its strength is justified is the Skeptic's question.
-
Pass Limitations are specific
Each limitation is specific to its item: e1 notes a normal is a 30-year average and Sea-Tac is south of central Seattle; e2 notes it is a comparison set, not a ranking, and rounding of summed monthly values; e3 notes a 0.01-inch day and a multi-inch day both count once and liquid-equivalent inclusion; e4 notes topography does not assign one amount and cloudiness is not precipitation. Rule satisfied.
-
Pass Tone is measured and respectful
Language is measured ('understandable but imprecise', 'The most accurate conclusion is that Seattle is frequently wet'). Objection responses are respectful and evidence-based, e.g. 'That is a real limitation.' No ridicule or unjustified absolutes such as 'proves' or 'definitively'.
-
Pass Readers can verify it
Sources carry meaningful role labels ('Primary station-normal data', 'Cross-city occurrence comparison', 'Topographic and rain-shadow context'), full titles, and descriptions of why each was chosen. Key figures are anchored to NOAA station IDs (USW00024233, USW00012839, etc.) and a reproducible method. Method steps cover claim definition (step 1), evidence not resting on one source (steps 6-7), sources reviewed (steps 3-7), and recorded limits (step 8). Two sources (NWS, NPS) lack identifiers, but their URLs and titles identify them; not a rule breach worth reporting.
