Hurricanes- Why do most hurricances strike land in the middle of the
night. Power lines are down and everyone is in the dark. Why don't
some hit at noon or in the afternoon?

"A perusal of landfall times from a book of storm tracks kept by
Charles Neumann shows that over the past 11 years, 13 hurricanes and
tropical storms have crossed the U.S. or Mexican coasts at night (7:00
p.m. to 7:00 a.m. EST) and 20 have crossed during the day. For
Category 2 hurricanes and above (those with maximum sustained winds
above 95 m.p.h.), six occurred during the night: Fran in 1996, Erin in
1995, Andrew in 1992 (two nighttime landfalls, one in Florida and the
other in Louisiana), Hugo in 1989, and Gloria in 1985 (the first of
its three landfalls occured on the Outer Banks of North Carolina)."
In the August/September 1997 issue of Weatherwise,

Left out the second part of the information..sorry:

"Six hurricanes also crossed the coast during the day: (Bob in 1991,
Gilbert in 1988 (two daytime landfalls, one in Yucatan and the other
in Mexico south of Brownsville), Elena in 1985, Gloria in 1985 (when
it hit Long Island and New England), and Kate in 1985. By coincidence,
four of the six night landfalls occurred in the past five years
whereas five of six day landfalls occurred between eight-eleven years
ago, and none has occurred since 1991"

Bear in mind this is from an article in 1997.  I am looking for more current data.
