Meteorological Analysis
|
Earl originated from a tropical wave which moved off the African coast on
August 10th. The wave soon developed into a tropical depression while it was
1000 nm E of the Lesser Antilles on the 13th. The strong sub-tropical ridge to the north of
the tropical depression caused the depression to move west at 20+ knots its
whole life. This is usually deadly for a tropical cyclone (and was eventually fatal
for the depression). Banding improved in the depression initially though and it
strengthened into tropical storm Earl on the 14th, 325 nm E of Barbados. Earl
moved through the Islands on the 15th with 50 mph winds and brought tropical
storm conditions, although briefly, to Grenada, St. Vincent, and the Grenadines.
The fast motion of Earl caused it to degenerate into a strong open wave on the
same day though, as the low level circulation got destroyed. The wave made it
into the Pacific eventually and became hurricane Frank on August 23rd.
