The category of severe weather alerts service and the form of the "alertAreas - name"

Question

Hi, with regard to severe weather alerts service, I have the following questions:

1.In the alerts provided, whether the following alerts are contained? Is there documentation showing all alert categories?

• Tropical storm / Tropical cyclone
• Thunderstorm / severe thunderstorm
• Tornado
• Blizzard
• High wind
• Flood / Flash flood
• Bushfire

2.If there are multiple locations that issue current alert, is it expressed in the form of "alertAreas - name" like "A-B-C-D"?

Answer 1

There is no definitive list of all possible alerts that could be returned. This is the case for most weather services as the types of weather alert categories has been evolving/growing over time. Here is a list of some of the types of weather categories I've seen for severe weather from NOAA:

As for your second question, the alert areas property is an array of objects. Each of these objects provide details about a single area. So the alert area would be something like [ { name: "first area", ...}, {name: "second area", ... }]

Hi @psj Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

Is there documentation showing all alert categories

You can get details on the weather alerts from the documentation Weather - Get Severe Weather Alerts. The service can return details such as alert type, category, level and detailed description about the active severe alerts for the requested location, like hurricanes, thunderstorms, lightning, heat waves, high winds, or forest fires.

If there are multiple locations that issue current alert, is it expressed in the form of "alertAreas - name" like "A-B-C-D"?

Unfortunately, this API will return the weather conditions at a given coordinate location only. If multiple alerts are active for the same location, the alerts will be returned in order of priority within the API response.

If you are interested in getting to know the weather conditions along a route, you can utilize the API Weather - Get Weather Along Route. This API returns hyper local (one kilometer or less), up-to-the-minute weather nowcasts, weather hazard assessments, and notifications along a route described as a sequence of waypoints. This includes a list of weather hazards affecting the waypoint or route.

Here is another resource that will guide you on how to test and use the APIs - Request real-time and forecasted weather data using Azure Maps Weather services
