The eye is a region of mostly calm weather found at the center of
tropical cyclones and is a well-recognized feature. It is usually
circular, typically 30–65 kilometers (19–40 miles) in diameter and
is at the cyclone's center of circulation. A cyclone's lowest barometric
pressure occurs in the eye, and can be as much as 15 percent lower than
the pressure outside the storm. In strong tropical cyclones, the eye is
characterized by light winds and clear skies, surrounded on all sides by
an eyewall, a normally symmetric ring of towering thunderstorms where
the most severe weather of a cyclone occurs. In weaker tropical
cyclones, the eye is less well defined, and can be covered by the
central dense overcast, an area of high, thick clouds that show up
brightly on satellite imagery. Weaker or disorganized storms may also
feature an eyewall that does not completely encircle the eye, or have an
eye that features heavy rain.

Wikiquote quote of the day:
I renounce war for its consequences, for the lies it lives on and
propagates, for the undying hatred it arouses, for the dictatorships it
puts in place of democracy, for the starvation that stalks after it. I
renounce war, and never again, directly or indirectly, will I sanction
or support another.
--Harry Emerson Fosdick
