How can I access weather alerts in real time? Is there a webhook?

[john01dav]

When I look into using the API, I see that I can poll for weather warnings and other alerts (tornado warnings are the most relevant to my use case), but I do not see any way to immediately be notified when such a warning is issued. Is there a webhook or similar that I can use? For some warnings, like tornado warnings, the few minute delay from polling is a real problem.

As far as I've seen, there are no webhooks (a "push" of data). I have seen other weather services offer this as a feature. But, my guess is that they also pull from the NWS so you'll probably still looking at some sort of delay.

A push alerts service would be really nice to have.

NWS has a "push" service in NWS Weather Wire, a stream of text products and CAP-formatted alerts. NWWS is transmitted either via satellite or via NWWS-OI, an XMPP chatroom. The delay on NWWS-OI is very short, text products are almost real time and CAP alert versions lag by a few seconds. There isn't much software out there to use NWWS-OI-- there's a basic python daemon and some commercial software--and it requires customization for whatever you want to do with the products. Not a product for beginners, but probably your best source if you wanted to develop a web push service.
