WEATHER
ECHO TOP – press the ECHO TOP softkey to show
the location, elevation and direction the highest
radar echo. This may not indicate the top of a
storm or clouds, only the highest radar return
echo. The information is derived from NEXRAD
information and indicates the highest altitude at
which precipitation is falling. ECHO TOPS and
Radar coverage are activated at the same time.
ECHO TOPS are mutually exclusive from both
NEXRAD and CLOUD TOPS, that is, when ECHO
TOPS is activated, NEXRAD and CLOUD TOPS
are removed. Refer to the Legend for a descrip-
tion of the ECHO TOPS coding. The update rate
is every 7.5 minutes.
NOTE: Cloud Tops and Echo Tops use the same
color scaling to represent altitude. Turning on
both products at the same time is not allowed.
