Access historical alert more than last 7 days

[clearlqy99]

I'm interested in performing some analysis on historical weather alert data. Based on API documentation, the https://api.weather.gov/alerts endpoint provides historical alerts for the last 7 days. Is there any possible way to access historical data for a longer time span?

Thank you.

I do not believe the NWS/NCEI has such archives of these alerts. My work has a couple of resources that aren't exactly APIs, but may help your analysis.

• per UTC date/hour archives of the raw CAP text messages
• GIS/KML/Excel downloads of VTEC enabled events
• Varios adhoc JSON services that may be helpful.

Please let me know [email protected] of any questions / help you need with what you are hoping to do.
