.SYNOPSIS...In the wake of Hurricane Erin, the central Atlantic
high pressure will build west-southwestward toward the Bahamas.
This will allow for the normal trade wind flow to return to the
regional waters. A long period northerly swell from Erin will
impact the area into the weekend, resulting in hazardous seas
for the Atlantic waters and passages. An area of disorganized
showers and thunderstorms associated with a tropical wave is
located a couple hundred nautical miles ENE of the northern
Leeward Islands. Environmental conditions appear conducive for
further development of this system, and a tropical depression is
likely to form this weekend while it moves northwestward and then
northward, in between the Lesser Antilles and Bermuda. This
system has a high chance of tropical cyclone formation, and
regardless of development, expecting increasing winds and
building seas with it.
