Browse All Calculators Read the FAQBegin with an official forecast, then choose a resource that matches the action you may need to take. Watches and outlooks are an invitation to prepare; warnings and local restrictions call for immediate attention. A calculator can summarize conditions for a location, while a guide explains the consequences and a government source provides authoritative alerts.
Check timestamps whenever conditions are changing. Snowfall totals issued two days before a storm may shift, and a mixed-precipitation forecast can become more or less hazardous with a small temperature change. Save school, utility, transportation, and municipal notification pages before service is disrupted. Households should also keep key phone numbers and medication details available offline.
Use at least two kinds of information for a consequential choice: an official alert plus a local report, or a calculator result plus the latest district message. Road treatment, terrain, lake-effect bands, and power infrastructure are too local for a broad forecast to capture perfectly. If sources disagree, follow the more cautious official instruction until conditions are clarified.
Review your plan after each winter event. Replace used supplies, note routes that became hazardous, and update family contacts. Preparation works best as a routine rather than a last-minute shopping trip.
You do not need dozens of bookmarks. Save the official weather office for your location, your municipality or county, the school district, the road or transit agency, and the electric utility. Add one family contact outside the immediate area. Confirm that notifications are enabled before the season begins and after changing phones.
Keep a paper copy of critical contacts in an emergency kit because power, mobile service, or a saved browser session may fail. Review links at the start of winter and remove outdated social accounts or unofficial reposting pages. During a storm, prefer a dated bulletin on an agency website over an undated screenshot.
Our tools can help prioritize preparation, but the resource list should remain useful even when this site or a weather API is unavailable.
For community planning, make the list accessible to everyone who may need it. Use clear labels, include telephone alternatives where available, and avoid relying on a single social network. People with disabilities, limited transportation, language needs, or electrically powered medical equipment may require earlier preparation. Local emergency management offices can identify public programs and warming locations. Confirm availability directly because hours, eligibility, and capacity can change during an event.
