Be careful! Pat was correct when he said OWM does not support alerts. The alerts in OWM are not at all the same as alerts in DarkSky which are textual time-sensitive messages that are relayed from the local weather service that warn of severe weather of some kind. Even if OWM had the same kind of alerts as DarkSky, the free plan only allows for 50 API calls a day compared to over 1000 for DarkSky. So if you poll the forecast API once an hour to get forecast data, that only leaves 26 API calls for alerts which means polling for them only once an hour which is not often enough for time-sensitive information. However, the OWM alert API is to implement custom triggers so one can be alerted when certain weather conditions change beyond a certain user-defined threshold such as for temperature or wind, etc. The API does not return textual alert messages from the local weather service the way DarkSky does. In any case, when and if alerts are supported, they should be checked in a more timely manner than forecasting data. However, some alerts are so time-sensitive that several minutes can mean life or death. So alerts should show some disclaimer that they may be delayed and not to rely on the site for critical weather information and decision making. -Bill > We invite you to try our new product - the weather alerts which are based > on our meteorological data. > Now you can use simple syntax and a few API methods to create triggers > which will fire on an occurrence of the selected weather conditions > (temperature, humidity, pressure, etc.) in a specified period of time.... > If the trigger's conditions are met, our service will generate an alert. > In order to receive this alert you need to poll the service with the > specified time interval.
