Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...Tropical Storm Jerry is near 15.7N 57.7W at 5 AM
EDT, moving west-northwest at 17 kt. Maximum sustained winds are
55 kt with gusts to 65 kt, and the minimum central pressure is
999 mb. Jerry will move to 17.0N 59.7W this afternoon, near
18.8N 61.7W Thu night, just northeast of the N Leeward Islands,
strengthen to a hurricane near 21.2N 62.8W Fri afternoon, to the
N of the Leeward Islands, then continue moving northward and
away from the Caribbean Fri night through Sun. Brief fresh to
strong southerly winds will impact the Leeward Islands Fri.
Otherwise, no significant wind from Jerry is expected to impact
the Caribbean. However large E swell will move through the
Caribbean passages of the Leeward Islands Thu afternoon through
