Real-Time Weather Monitoring and Alert System
A serverless, real-time weather monitoring system that fetches live weather data from the OpenWeatherMap API, stores and analyzes it on AWS, triggers alerts for extreme conditions, and provides visualization through Athena and QuickSight. The solution is cost-effective, scalable, and fully automated.
Overview
2025,
usecase
This project continuously ingests weather data for multiple cities and processes it using AWS Lambda. The data is stored in Amazon S3 for raw records and Amazon DynamoDB for current weather snapshots. Amazon SNS delivers alerts for extreme weather conditions, while AWS Glue and Athena enable querying and analysis of historical data. Amazon QuickSight (optional) provides dashboards to track weather patterns and trends. The system is fully serverless, ensuring low cost, high availability, and scalability.
Process
1. Ingest
Weather data is fetched in real time from the OpenWeatherMap API by AWS Lambda and stored in Amazon S3 for further processing.
2. Analyze
The ingested weather data is processed by AWS Lambda, where conditions (e.g., high temperature, strong winds) are checked to identify extreme weather.
3. Store
Analyzed weather information is stored in Amazon DynamoDB for structured access and quick retrieval of the latest conditions.
4. Notify
Amazon SNS sends real-time alerts (e.g., email notifications) to users or admins when extreme weather is detected.
5. Queue
Incoming weather data can be buffered in Amazon SQS to ensure reliable delivery and decoupling between producers and consumers.
6. Archive
Raw and processed weather data is stored in Amazon S3 for durability, historical reference, and analytics.
7. Catalog
AWS Glue crawls and catalogs the weather data in S3, making it query-ready with a defined schema.
8. Analyze
Amazon Athena is used to run SQL queries on historical weather data for deeper investigation and trend discovery.
9. Visualize
Amazon QuickSight provides dashboards and visualizations such as temperature trends, city-based heatmaps, and alert summaries.
Outcome
The outcome of the weather monitoring project is a scalable, real-time platform that continuously ingests live weather data from the OpenWeatherMap API and processes it for actionable insights. Extreme conditions are detected and communicated instantly through alerts, while current and historical records are stored in DynamoDB and S3 for analysis. Using Glue and Athena, stakeholders can query and discover trends, while QuickSight provides visual dashboards for monitoring weather patterns across cities. The system supports safety, planning, and decision-making, delivering a cost-effective and fully serverless solution.
