PettusPlots ("the Service", "we") is a weather visualization website operated by James Pettus. By accessing the Service you agree to these Terms of Service. If you do not agree, do not use the Service.
PettusPlots renders and displays weather data — radar, satellite imagery, model output, tropical cyclone products, soundings, mesoanalysis, space weather, and related graphics. The Service is under active development: features may be added, modified, suspended, or discontinued at any time without notice.
The Service is provided for informational and educational purposes only. Never use it as your sole source for decisions involving the protection of life or property. Data may be delayed, incomplete, mislabeled, or wrong; rendering pipelines fail; servers go down — often precisely when severe weather is happening. For warnings and life-safety decisions, rely on official sources: the National Weather Service (weather.gov), the Storm Prediction Center, the National Hurricane Center, and your local emergency management officials.
The Service visualizes data produced by third parties, including NOAA and its offices (NWS, NCEP, SPC, NHC, NESDIS), the ECMWF (open data, CC-BY-4.0), Deutscher Wetterdienst, the Canadian Meteorological Centre, the UK Met Office, the Japan Meteorological Agency (Himawari), EUMETSAT, and others. Underlying government data is generally public domain or openly licensed; the providers do not endorse this site. Base maps are provided by Mapbox. Attribution for specific plots appears on the plots themselves, including vendored open-source rendering code where used (e.g. Tim Supinie's vad-plotter).
We may restrict or revoke access at our discretion, particularly for abuse or unauthorized API use.
Donations are processed by Stripe; your card details go to Stripe, not to our server. Donations are voluntary gifts that fund hosting and development — they are non-refundable, confer no goods, services, features, or expectations, and are not tax-deductible (PettusPlots is not a charity).
The PettusPlots name, logo, site design, and original rendering code are the property of James Pettus. Underlying meteorological data belongs to (or is licensed from) its providers. Open-source components remain under their own licenses.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ACCURACY, TIMELINESS, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. NO UPTIME OR AVAILABILITY IS GUARANTEED.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, JAMES PETTUS AND PETTUSPLOTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES — INCLUDING DAMAGES ARISING FROM RELIANCE ON WEATHER INFORMATION DISPLAYED BY THE SERVICE, LOSS OF DATA, OR SERVICE INTERRUPTION — EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TOTAL LIABILITY FOR ANY CLAIM SHALL NOT EXCEED THE AMOUNT YOU HAVE DONATED TO THE SERVICE IN THE PRECEDING TWELVE MONTHS, OR TEN DOLLARS, WHICHEVER IS GREATER.
We may update these Terms at any time; the effective date above will change when we do. Continued use of the Service after changes constitutes acceptance.
These Terms are governed by the laws of the State of Tennessee, United States, without regard to conflict-of-law rules. Questions: [email protected] or the contact form.
