Synopsis for the Gulf of Mexico
409 PM EST Sun Jan 20 2019

.SYNOPSIS...A strong cold front has exited the area, and is now
over the northwestern Caribbean Sea from west-central Cuba to
northern Belize. Strong winds and high seas across most of the
central and eastern gulf will slowly subside through early Mon.
Strong high pressure in the wake of the front covers the entire
basin. The high pressure will shift eastward in as low pressure
deepens over the southern Plains allowing for strong southeast to
south return flow to develop in the western Gulf of Mexico by Tue
morning. The strong return flow will expand to the eastern Gulf of
Mexico by Tue night. Another strong cold front is expected to
move across the NW Gulf of Mexico by Wed morning, with the
possibility of gale force northerly winds behind it over the far
western Gulf and near the coast of Mexico. This front will reach
from near the NE Gulf to the Yucatan Peninsula early Thu and
weaken as it exits the SE Gulf Thu night followed by fresh to
strong northerly winds.
