/* Get my weather object */const url = "<https://weatherkit.apple.com/1/weather/en-US/41.029/-74.642?dataSets=weatherAlerts&country=US>"

const weatherResponse = await fetch(url, {headers: {"Authorization": token}});const weather = await weatherResponse.json();

/* Check for active weather alerts */const alerts = weather.weatherAlerts;const detailsUrl = weather.weatherAlerts.detailsUrl;
