Data Sources, Tool Limitations & Advertising Disclosure
Data Sources
Weather variables and forecast indicators used in on-site calculators are obtained through licensed or publicly available weather data APIs and recognized forecast data providers. These feeds may include national meteorological agencies and reputable commercial weather services. Data is used in structured form to support automated estimation models and educational explanations.
Referenced organizations and agencies are cited for transparency and learning context only. Their data frameworks and public documentation help inform interpretation methods, but no endorsement or affiliation is implied.
Users can review additional technical and interpretation details on the Accuracy & Data Sources Statement and Editorial & Methodology Policy pages.
Tool Limitations
All calculators and probability scores provided on this website are automated estimates based on forecast inputs and defined logic rules. They are not official determinations and do not account for many real-world operational factors used by institutions when making closure or safety decisions.
Limitations may include:
• forecast model uncertainty
• regional data gaps or timing delays
• local micro-conditions not reflected in feeds
• non-weather institutional decision factors
• sudden condition changes after data updates
Results should be treated as informational guidance only. Official announcements from schools, authorities, and weather agencies always take precedence.
