NEXRAD – press the NEXRAD Softkey to show
NEXRAD weather and radar coverage information.
Areas where radar coverage is not available will be
shown in grayish-purple. The display is updated
every five minutes.
NEXRAD Limitations
Certain limitations exist regarding the NEXRAD radar
displays. Some, but not all, are listed here:
• NEXRAD base reflectivity does not provide
sufficient information to determine cloud layers or
precipitation characteristics (hail vs. rain, etc).
• An individual NEXRAD site cannot depict high
altitude storms at close ranges and has no information
about storms directly over the site.
• The resolution of displayed NEXRAD data is 4
square kilometers. Therefore, when zoomed in on
the display, each square block is 2 kilometers on
each side. The intensity level reflected by the square
will be the highest level sampled within the square
area.
ECHO TOP – press the ECHO TOP Softkey 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. ECHO
TOPS cannot be displayed along with NEXRAD and
CLOUD TOPS. When ECHO TOPS is activated,
NEXRAD and CLOUD TOPS are removed. Refer
to the Legend for a description of the ECHO TOPS
coding. The display is updated every 7.5 minutes.
CLD TOP – press the CLD TOP Softkey to show the
cloud top altitude determined from satellite imagery.
The display is updated every 15 minutes.
LTNG – pressing the LTNG Softkey shows the location
of cloud-to-ground lightning strikes. The display is
updated every five minutes.
NOTE: Strikes depicted represent cloud to ground
strikes within a 2 kilometer radius of the actual
strike location. Therefore, the exact location of
the strike is not displayed.
