1100 PM AST Fri Sep 28 2018
Even though there still appears to be a circulation center in
satellite imagery, an Air Force Reserve Hurricane Hunter plane was
unable to find westerly winds that would support a closed
circulation. Therefore, Kirk has degenerated into an open wave,
and this will be the last advisory. The SFMR on the plane still
measured winds around 35 kt in the convection to the east of the
wave axis, and that will remain the initial intensity.
The wave will continue moving westward across the Caribbean Sea
during the next few days, with its winds gradually decreasing due
to continued westerly shear. Heavy rains are still possible over
portions of eastern Puerto Rico and St. Croix during the next day
or two while Kirk's remnants pass to the south.
