An Evaluation of the Weather Warning Process and Weather Communication Modalities

Communicating weather warning information using innovations in delivery modalities has become a very complex process. Defining the message for these modalities and delivering these messages in a timely manner has proven to be complex and has created a messaging process worthy of detailed study. This presentation reports on the weather information needs of end users in the warning partnership and the use of weather information delivery modalities in actual weather events and situations, including mobile apps, NOAA Weather Radio, alert notification systems, social media, and more. The strengths and weaknesses of the various modalities will be discussed, along with an analysis of what may work best in various event scenarios and with different populations and warning partners. Implications for the warning delivery process will be discussed.
