Hurricane Danny - July 14-28, 1997

The origin of Danny was a cluster of strong to severe thunderstorms that swept through the Lower
Mississippi valley on the 13th.  The convective mass drifted southward into the Gulf of Mexico,
and formed a surface low south of the Bayou State on the 14th.  Initially drifting westward, the
cyclone increased its areal extent, but surface winds remained weak.  It wasn't until the 16th,
when the system started tracking northeast that the tropical cyclone gained organization.  Upper
level southwesterlies hindered development, but Danny persisited, becoming a tropical storm
early on the 17th and a hurricane that night.  Danny continued its east-northeast track, against
the forecast models consensus opinion mainly because the models has a poor handle on the
upper level environment in the Gulf of Mexico.

Danny made landfall near Empire and Buras, Louisiana early on the 18th.  As it was a small
system, effects were minimal across Louisiana.  It peaked in intensity south of the Mississippi
coast later that day, before stalling in Mobile Bay on the 19th.  Danny moved slowly along the
coast until the morning of the 20th, when it finally moved well inland of Pensacola.  Thereafter,
its organization remained very good as upper level winds were ideal for its maintenance,
despite its location over land.  Danny crawled northward across Alabama on the 22nd,
before resuming its east-northeast course across the Carolinas ahead of a stalled frontal

Restrengthening over North Carolina, Danny acquired tropical storm force winds over land
as it was becoming a nontropical cyclone. The extratropical transition was complete on the
25th, but the cyclone remained rather close to the coast of New England. Occluding that day
while it nearly stalled south of Cape Cod, the storm finally moved out to sea, moving well
southeast of the Canadian maritimes.  Its track lies below, provided by the National Hurricane

Danny initially stalled on the 19th and 20th, and maxima farther along the track where the precipitation
intensified each morning, in western Alabama (21st), eastern Alabama (22nd), northern Georgia (23rd),
the central Carolinas (24th), northern New Jersey (25th), and Cape Cod (26th).
