OPTIONAL EQUIPMENT
ECHO TOP – Press to show the location, elevation,
and direction of 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 fall-
ing. ECHO TOPS and Radar coverage are acti-
vated 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 description 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.
RADAR COVERAGE – The display of Radar
Coverage is always active when NEXRAD and
ECHO TOPS are selected and indicates the cur-
rently available NEXRAD Radar coverage and
ECHO TOPS areas by showing the area in a gray-
ish-purple color where information is not being
collected. Areas where radar capability exists, but
is not active or is off-line, will not be shown as
available. Areas where radar coverage is not avail-
able will be shown in grayish-purple. The update
rate is every five minutes.
CLD TOP – Press to show the cloud top altitude
determined from satellite imagery. Refer to the
legend for a description of the CLOUD TOPS
color coding. The update rate is every 15 minutes.
LTNG – Press to show the location of cloud-to-
ground lightning strikes. The update rate is every
five minutes.
NOTE: Strike location falls within a 2 km region.
Therefore, the exact location of the strike is not
displayed.
CELL MOV – Press to show the storm cells identi-
fied by the ground-based system. The movement
is depicted by an arrow. The update rate is every
12 minutes.
