Alerts Radar — Weather & Disaster Warnings

Official warnings from national weather and disaster services in one clean schema: floods and heavy rain, storms and cyclones, lightning, heat, cold, drought, wildfires, earthquakes, tsunamis and volcanoes. Filter by country, hazard, severity and area; schedule it and get only new alerts as a dataset, an RSS feed, a Slack message or rows in Google Sheets.

Built for logistics and supply-chain teams, insurers and risk analysts, agriculture and energy operators, travel and event companies, field-service and facility managers, newsrooms, and AI agents that need to know where the weather is turning dangerous.

Why this Actor

• One schema for every service. event, hazard, severity, urgency, certainty, headline, description, instruction, areas, sentAt, onset, expires, sender, url, plus magnitude and point for earthquakes.
• Hazard types across languages. "Tempestade", "Gewitter", "Flash Flood Warning" and "Squally weather" all land in one hazard value (storm, flood, heat, cold, drought, fire, earthquake…).
• Only what matters. States or provinces (pick from the list or type Kerala, Texas, IN-MH; misspellings get a suggestion), minimum severity (moderate by default), hazards, district or city names and keywords; expired alerts are left out.
• Alert feeds. Turn on Only new alerts and schedule it every 15 minutes or hourly: each run returns only what earlier runs didn't deliver. Follow the Standby URL with &format=atom in any feed reader, or send results to Slack, Discord, Google Sheets or a webhook.
• For AI agents. Callable as an MCP tool.

Good to know

These are copies of official warnings for monitoring and analysis, not an emergency notification service: always follow the issuing authority. When you republish alerts, show the attribution and the issue time and link to the source. MeteoAlarm asks redistributors to publish: "Time delays between this website and the www.meteoalarm.org website are possible. For the most up-to-date awareness information as published by the participating National Meteorological and Hydrological Services, please refer to www.meteoalarm.org."
