Foreword 4.7.9 Echo Tops NOTE: Due to similarities in color schemes, the display of Echo Tops is mutually exclusive with Cloud Tops and NEXRAD. Echo Tops data shows the location, elevation, and direction of the highest radar echo. The highest radar echo does not indicate the top of a storm or clouds; rather it indicates the highest altitude at which precipitation is detected. Information is derived from NEXRAD data.
