The SMN categorizes alerts into yellow, orange, and red levels, indicating increasing severity and potential impact on society, life, property, and the environment. Yellow alerts suggest potentially dangerous conditions, especially for vulnerable groups, while orange and red alerts warn of more severe and exceptional phenomena posing risks of emergencies or disasters.
