National Weather Service AI Analysis
detail.loadingPreview
Automate the retrieval and analysis of National Weather Service alerts. This workflow processes real-time weather data, filters for critical alerts, and extracts key information for immediate action.
About This Workflow
This n8n workflow is designed to provide an intelligent and automated way to monitor National Weather Service (NWS) alerts. It begins by listening for incoming requests via a webhook, which should include latitude and longitude coordinates. The workflow then queries the NWS API to fetch active alerts for the specified location. It parses these alerts, focusing on 'actual' status events, and then meticulously cleans the data by removing irrelevant fields, retaining only the essential details like description, severity, and instructions. Finally, it applies crucial filters to isolate alerts based on severity (Moderate, Severe, Extreme) and ensures that only currently effective alerts are processed, making timely and actionable weather information available.
Key Features
- Real-time NWS Alerting: Fetches active weather alerts directly from the National Weather Service API.
- Location-Specific Data: Utilizes latitude and longitude to pinpoint alerts relevant to a specific area.
- Intelligent Filtering: Filters alerts by status ('actual') and severity (Moderate, Severe, Extreme).
- Data Normalization: Cleans and standardizes alert data by removing extraneous fields.
- Timeliness Check: Ensures only currently effective alerts are processed.
How To Use
- Configure Webhook: Set up the initial Webhook node to receive incoming data containing
latitudeandlongitudeJSON properties. - Connect to NWS API: Ensure the
Get NWS Alertsnode's URL is correct and configure it to query forstatus=actualandpoint={{ $json.body.latitude }},{{ $json.body.longitude }}. - Process Alerts: Use the
Split Outnode to process each alert feature individually. - Clean Data: In the
Remove Irrelevant Fieldsnode, define the specific fields you want to extract from the NWS alert data (e.g.,id,properties.areaDesc,properties.severity,properties.headline,properties.description). - Filter by Severity: Configure the
Filter by Severitynode to include alerts withModerate,Severe, orExtremeseverity. - Filter by Effectiveness: Utilize the
Filter by Effectivenode to ensure only currently active alerts are passed through by comparing theeffectivedate with the current date. - Filter by Status: Apply the
Filter by Statusnode to confirm the alert status isactual.
