a. Synoptic History
Barry originated from a tropical wave which moved off the
African coast on 7 July. By the 9th, a low level circulation was observed
and this indicated that Tropical Depression Three had formed midway between
Africa and the Lesser Antilles. The depression tracked north-westward,
reaching tropical strom strength on the 11th and weakening back to a depression
on the 13th. It then dissipated into an elongated trough with several
minor eddies. Barry's closest point of approach to land was about 475
nautical miles northeast of the Leeward Islands.
On the large scale, the storm's motion was northwestward
in response to low pressure over the Canadian Martime Provinces and high
pressure centered north of the Azores. There was a track oscillation on
the 12th and 13th, during which time the best track initial motion varied
from northwestward to west southwestward.
b. Meteorological Statistics
The only aircraft reconnaissance was flown on the afternoon
of the 12th and a small area of tropical storm force winds were measured
to the northeast of the center. The maximum wind speed reported was 55
mph at 1500 feet and the minimum pressure was 1010. The highest surface
wind speed estimate from the aircraft was 46 mph.
