Explanation:
A large and dangerous hurricane has developed in the Gulf of Mexico.
The featured time-lapse video
shows
Hurricane Harvey
growing to
Category 4
strength over the past few days, as captured by
NASA and
NOAA's
GOES-East satellite.
Starting as a slight dip in
air pressure,
hurricanes
swell into expansive spiraling
storm systems, complete with
high
winds and driving rain.
Hurricanes are
powered by evaporating ocean
water,
and so typically
gain strength
over warm water and lose strength over land.
Much remains unknown about hurricanes and
cyclones, including details of
how they are formed
and the exact path they will take.
Hurricane Harvey, accompanied by a dangerous
storm surge,
is expected to make landfall sometime today in
Texas.
