Echo Tops
Echo Tops are derived from NEXRAD radar and indicate the highest altitude at which precipitation is falling. Echo Tops at or
above the altitude you select are displayed, in 5,000 foot increments up to 70,000 ft. Echo Tops can be helpful in determining the
severity of thunderstorms. (higher = more intense)
Echo Tops for all altitudes
