The NOAA Hurricane Dorian forecast-statement controversy
Editorial record through October 30, 2026. Later developments are not reflected here.
Remember when?
After Trump disputed a weather-service forecast concerning Alabama and Hurricane Dorian, NOAA issued an unsigned statement criticizing its own Birmingham office. An inspector general later found that Commerce Department leadership drove a flawed process.
What the record establishes
On September 1, 2019, the National Weather Service office in Birmingham, Alabama, publicly reassured residents that Alabama would not be affected by Hurricane Dorian. Following statements by Trump and a White House request for a correction or explanation, NOAA issued an unsigned September 6 statement criticizing the Birmingham office. The Commerce Department inspector general investigated and issued report OIG-20-032-I on June 26, 2020. It concluded that Commerce led a flawed process discounting NOAA participation, required NOAA to release a statement that did not serve NOAA or the weather service, and failed to account for the Birmingham office’s public-safety purpose. The inspector general also documented deletion of relevant texts by one NOAA employee and outdated departmental records guidance.
Why it matters
Warnings about dangerous weather must be reliable and insulated from pressure to protect political reputations. The episode illustrates how even an ostensibly small dispute about a forecast can undermine trust in technical experts.
Administration response and strongest counterargument
The White House requested a correction or explanation in response to what it viewed as conflicting forecast information. Forecast tracks evolve, and elected officials may communicate emergency risks. The inspector general examined the process behind NOAA’s specific statement; its findings do not establish that every forecaster or official knowingly fabricated weather data.
The official inspector-general investigation
The Commerce Department inspector general’s June 26, 2020 evaluation, OIG-20-032-I, examined NOAA’s September 6, 2019 statement about Hurricane Dorian. It found that Commerce leadership used a flawed process that discounted NOAA’s participation and required a statement that did not advance NOAA or National Weather Service interests.
The review also emphasized the public-safety purpose of the Birmingham forecast office’s September 1 message that Alabama would not experience Dorian impacts. The finding is evidence of improper handling and institutional pressure; it is not, by itself, a finding that every weather forecast made during the dispute was knowingly falsified.

Evidence and competing interpretations
The Commerce Department inspector general examined NOAA’s September 6, 2019 statement criticizing its Birmingham forecasting office. The review found flaws in the process and external pressure around the statement. This does not alone establish a broad administration-wide policy to falsify climate research.
Legal status and evidentiary limits
The June 26, 2020 Commerce inspector-general report made administrative and scientific-integrity findings, not a criminal conviction or a court judgment against Trump. The focus is the September 6 statement and process, not general climate policy.
