There
are
signs
that
El
Nino,
the
massive warming of the Pacific Ocean
that
affects
the
world's
weather,
may
be forming again.

A satellite orbiting 600 miles above
the Pacific Ocean picked up a streak of
warm
water
forming
along
the
equator
—

an
early
sign
of
the
phenomenon
felt
around
the
world
when
it
last
appeared,
just
four
years
ago.

It
is
more
than
3,000
miles
long.
The water in it is nine degrees warmer
than
in
surrounding
areas
—

a
substantial
number
to
oceanographers.
The
warm
pool
is
growing
and
has
caused
government
forecasters
to
put
out
an
advisory
(
气象报告
) .


a
heads-up
in
advance
so
that
people
can
properly
be
prepared
for
this event.

and

Center.

If
a
full-blown
El
Nino
does
form,
Americans
would
most
likely
start
to
feel its effects next fall and winter.

The government called the forecast
very
preliminary
—

but
the
warning
allows
emergency
agencies
to
make
plans.


now,
we
can't
predict
whether
it
will
be
weak,
moderate
or
strong in intensity/' said Kousky.

Some scientists say it's too early to
predict
anything
at
all.

is

a
very
large
anomaly
(

)
in
the
Pacific
right
now,
and
we
need
to
watch
it.
But
these
things
are
very
difficult
to
forecast.

El Ninos can be both good and bad,
depending
on
where
you
are.
Even
a
relatively
small
one
can
bring
about
significant
changes
by
shifting
the
wind
patterns
from
the
Pacific
Ocean
that pass over the United States.


During
the
last
El
Nino,
in
1997
and
1998,
rainfall
doubled
in
California,
causing
a
$$1
billion
in
storm
damage.
On
the
other
hand,
in
Florida,
forest
fires
were
put
out
by
the extra rain.
