Tropical Cyclone Report
Tropical Depression Two
11 - 12 July 2001
Miles B. Lawrence
National Hurricane Center 23 July 2001
Tropical Depression Two originated from a tropical wave that
moved westward from the coast of Africa on 7 July. Evidence of a
weak low-level circulation was seen on visible satellite images on
the 10th and a small area of deep convection developed
over the circulation by the 11th. This, along with wind
observations from U.S. Navy drifting buoy number 41562, is the
basis for concluding that the wave became a tropical depression by
1800 UTC, 11 July, about 1000 n mi east of the Windward Islands. It
is possible that depression status may have been reached six to
twelve hours earlier.
The depression moved west-northwestward at about 15 knots with
little change in strength for the next 24 hours under the steering
influence of a strong subtropical ridge to the north. Vertical wind
shear disrupted the depression and, by late on the 12th,
last-light visible satellite images indicated that there was no
longer a closed low-level circulation. The depression dissipated
about 600 n mi east of the Windward Islands. The remnant open wave
produced showers across the Lesser Antilles on the 13th
and 14th.
