What this site does
Open the home page and, with your permission, it detects your location and instantly checks for active winter storm warnings, watches and advisories, then shows current conditions, a computed risk index and a 7-day snow-and-temperature forecast. We also publish a dedicated live page for hundreds of cities across the US, Canada, the UK, Ireland and beyond, plus a plain-English guide to what a winter storm warning means and winter weather news.
Where our data comes from
- Forecasts & current conditions come from Open-Meteo, an open weather-data API.
- Official warnings for US locations come directly from the National Weather Service (NWS / NOAA) via its public alerts feed. Outside the US, official-warning feeds vary by country, so we show our computed risk estimate and link you to the relevant national weather agency.
- Your location comes from your browser’s geolocation (only with your permission) or, as a fallback, an approximate IP-based lookup. It is used to fetch your forecast and is not stored by us.
- The 0–100 risk index is computed by us from the live forecast. We explain exactly how on the methodology page.
How we keep it accurate
Our guides and city pages are researched, written and fact-checked by the Winter Storm Warning editorial team against official sources such as the NWS and national meteorological agencies. Live data refreshes automatically; written content is reviewed and dated when it changes. If you spot something wrong, tell us and we will fix it.
