Potential Tropical Cyclone Ten - August 21-30, 2017
For several days, an area of disturbed weather persisted near the west
coast of Florida beginning on August 21st. A
surface low formed in association with the disturbance early on the
25th which drifted northeast across Florida,
entering Atlantic waters by the 28th. The National Hurricane Center
was concerned that the low pressure area could
develop a well-defined circulation, so advisories were initiated on
Potential Tropical Cyclone Ten when its center
was near the northeast Florida coast on the 27th. The system was near
a front at this point and never developed a
well-defined circulation, but did acquire tropical storm-force winds
east of the center on the 28th. The system
began to accelerate northeast, developing into a hurricane force
extratropical low by the 30th as it passed between
Bermuda and Atlantic Canada. The cyclone became absorbed into a larger
system in the North Atlantic on September 2nd
about 600 miles west of Ireland.
