Synopsis for the Gulf of Mexico
1105 PM EDT Tue Sep 17 2019

.SYNOPSIS...Tropical Depression Imelda is inland near 29.8N 95.5W
1007 mb at 11 PM EDT, moving farther inland to the north at 5 kt.
Maximum sustained winds are 30 kt gusts 40 kt, over inland area.
Imelda will weaken to a remnant low as it continues to move
inland overnight and the next couple of days, before dissipating
Fri. Meanwhile, high pressure will build over the north central
Gulf in the wake of Imelda tonight, supporting gentle to moderate
winds through mid week, except for moderate to fresh winds off the
west coast of Yucatan at night. The high pressure will dissipate
later in the week in advance of a weak cold front that is forecast
to move across the eastern Gulf of Mexico then stall and
dissipate over the southeast Gulf Fri into Sat. Fresh winds and
building seas will follow the front over the eastern Gulf Fri into
Sat.
