Meteorologists
have
always
felt
responsible
for
reducing
the
number
of
lives
lost
at
the
hands
of
severe
weather.
Over
the
years,
they
have
teamed
up
with
some
of
the
best
scientists
in
the
field
to
improve
the
accuracy
and
prediction
of
severe
weather
reports.
Meteorologists
think
that
residents
need
much
more
than
the
previously
typical
five
minute
warning
in
order
to
gather
their
loved
ones
and
seek
shelter.
Advancements
of
local
weather
radar
have
given
them
a
much
clearer
picture
on
what
path
a
storm
will
take,
allowing
them
to
warn
residents
in
the
area
as
soon
as
possible.
Meteorologists
and
scientists
have
been
able
to
successfully
track
severe
thunderstorms
and
possible
tornadoes
by
using
an
advanced
tracking
system
called
NEXRAD
(Next-Generation
Radar).
NEXRAD
is
a
tracking
network
made
up
of
158
Doppler
weather
radars.
This
high-resolution
computerized
system
takes
readings
on
the
amount
of
precipitation
in
the
air,
the
movements
in
the
clouds,
and
the
wind
speeds
during
a
storm.
These
readings
are
bounced
back
to
a
local
weather
computer,
and
a
colorful
image
is
rendered
on
the
screen,
giving
meteorologists
a
clear
picture
of
what
kind
of
weather
is
on
the
horizon.
This
final
image
is
what
you
see
when
the
meteorologist
breaks
in
with
severe
weather
reports
and
warnings,
usually
with
a
description
of
how
he
maps
weather
radar.
In
the
case
of
severe
weather,
the
meteorologist
will
relay
the
readings
found
by
the
local
weather
radar
to
the
residents
in
the
area.
Most
likely,
on
your
television
screen
you
will
see
a
computer
animated
image
of
the
approaching
storm.
If
the
storm
is
severe
enough,
then
the
National
Weather
Service
(NWS)
will
issue
severe
weather
reports
of
severe
thunderstorm
warnings
for
your
area.
In
that
case,
the
storm
captured
on
radar
will
have
produced
strong
readable
winds,
detectable
lightening,
and
some
hail.
Paying
attention
to
the
weather
map
is
vital
when
severe
weather
is
around.
On
the
television
screen
you
will
see
several
colors
on
the
precipitation
map,
ranging
from
blue
(the
lightest)
to
black
(the
heaviest).
If
the
colors
for
your
specific
area
are
yellow,
take
caution.
If
the
colors
range
between
orange
and
red,
take
cover
immediately,
as
damaging
winds
and
dangerous
lightening
have
been
reported.
Before
a
tornado
struck
Atlanta,
Georgia
in
2008,
local
meteorologists
warned
residents
of
severe
weather.
Local
weather
radar
had
picked
up
on
destructive
winds
inside
the
storm,
and
the
National
Weather
Service
issued
a
severe
tornado
emergency
when
reports
came
in
of
large
hail,
increasing
wind
speeds,
and
wind
rotation
within
the
storm.
One
resident
recalls:
"I
have
never
seen
a
storm
so
strong
that
the
radar
showed
the
color
as
being
black!"
Meteorologists
were
able
to
use
the
data
to
offer
a
predicted
storm
path,
giving
residents
enough
time
to
take
cover.
Paying
attention
to
your
local
meteorologists,
and
not
underestimating
the
accuracy
of
severe
weather
reports,
is
vital
to
your
safety.
