Tropical Weather Discussion
NWS National Hurricane Center Miami FL
608 AM EST Fri Dec 29 2017
Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.
Based on 0600 UTC surface analysis and satellite imagery through
0945 UTC.
...ITCZ/MONSOON TROUGH...
The monsoon trough extends from the African coast near 08N13W to
05N19W. The Intertropical Convergence Zone axis extends from
05N19W to 02N29W to 01N43W to the Equator near 46W. Scattered
moderate convection is from 02N-07N between 26W-47W.
...DISCUSSION...
GULF OF MEXICO...
Zonal westerly flow aloft prevails over the Gulf basin this
morning while a stationary front extends from the NE Gulf near
28N84W to 25N90W into a 1022 mb low centered near 25N96W. The
stationary front continues southward to 19N95W and inland across
interior portions of east-central and NE Mexico. Low stratus and
possible isolated showers are generally noted on satellite imagery
north and west of the frontal boundary while isolated showers
continue within 120 nm S of the front between 84W-93W. High
pressure lies to the north across much of the SE CONUS and eastern
Texas generating moderate to occasional fresh E-NE winds across
much of the basin. The frontal troughing across the western Gulf
waters is expected to remain in place through Saturday night while
surface ridging influences the eastern Gulf and Florida peninsula
through Sunday night. Thereafter...the next strong cold front is
expected to emerge off the Texas and Louisiana coasts Sunday late
afternoon into the evening.
CARIBBEAN SEA...
Middle to upper level ridging persists over the Caribbean basin
this morning with water vapor imagery indicating mostly dry and
stable conditions aloft. Moderate to fresh trades prevail and are
expected to persist through Tuesday. Low-level moisture
convergence is maximized across the western waters generating
isolated showers and tstms S of 16N W of 80W...and S of 20N W of
84W. This convection is expected to continue moving westward
across interior portions of Central America. Otherwise...little
change is expected during the next couple of days.
...HISPANIOLA...
A few isolated showers are moving across the region this morning
however mostly fair conditions are expected Friday for
Hispaniola. Mostly dry and stable W-NW flow will persist on the
eastern periphery of a upper level ridge anchored over the western
Caribbean.
ATLANTIC OCEAN...
A cold front enters the discussion area near 32N53W extending SW
to 28N61W becoming stationary to 30N75W and into a 1020 mb low
centered near 28N79W. A surface trough extends from 31N80W through
the low center to 26N80W. Isolated showers are noted on satellite
imagery along and N of the stationary front. Widely scattered
showers and possible isolated tstms are occurring N of 29N within
90 nm either side of the cold front. To the south...a pre-frontal
surface trough is analyzed from the central Bahamas near 24N75W
to 28N60W and is providing focus for isolated showers within 75
nm either side of the boundary. Otherwise...the remainder of
central and eastern Atlc is under the influence of a surface ridge
anchored by a 1028 mb high centered SE of the Azores near 34N20W.
One exception within the southwestern periphery of the surface
ridge is a middle to upper level low noted on water vapor imagery
near 24N36W generating scattered showers and possible isolated
tstms from 19N-26N between 32W-37W.
