Lightening strike data is nice and I was
able to see lightening strikes start ahead
of pop up thunder storms even before any-
thing else showed up on Radar. They are
color coded by age of the strike.
WxWorx was
started by pilots and
meteorologists to provide
a service to pilots
You are also able to use Storm Cell
Identification and Tracking markers or
SCIT markers. These identify the position
of potentially dangerous storms. WxWorx
displays two types of SCIT markers: Shear
Storm markers (generated when high wind
shear is detected) and Severe Storm mark-
ers (generated based on the presence of
several factors including maximum rain
rate, hail presence, and hail size). Click on
a SCIT marker and a window pops up with
information about the storm like max rain,
size of hail, storm movement and size.
Zoom in enough (less than 188 miles) and
the box will also have an arrow pointing
in the projected direction of the storm over
the next fifteen minutes.
While there is much to like about the
program I had a few gripes, although they
are minor:
• The zoom function is different than
most, you have to find the center of
where you want to zoom and move
out from there. It takes some getting
used to.
• With any of the top controls you
click once to activate it, such as zoom
or pan, and then perform the func-
tion. But if you didn’t zoom enough
