Tropical Weather Discussion

146 AM EDT Sat Apr 1 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 0000 UTC surface analysis and satellite imagery through 
0545 UTC.

...ITCZ/MONSOON TROUGH...

The Monsoon Trough extends from the African coast near 11N16W to 
09N18W. The Intertropical Convergence Zone extends from 01N11W to
the coast of South America near 04S38W. Scattered moderate 
convection was noted within 100 nm on either side of the ITCZ.

...DISCUSSION...

GULF OF MEXICO...

A weakening stationary front extends from the Tampa Bay area to 
28N83W to 25N87W to 24N90W. South of this feature, a squall line
extends from 26N83W to 25N86W. Scatterometer data depicts gentle
to moderate southeasterly winds west of 93W while light to gentle
easterly winds prevails elsewhere. Expect for the front to
dissipate today. 

CARIBBEAN SEA...

A large upper-level anticyclone centered over northern Venezuela 
dominates the flow over the Caribbean with strong mid to upper 
level subsidence over the basin. At the surface, conditions 
remain relatively tranquil across the basin. Light to moderate 
trade winds were noted over the basin. Little change in the 
overall conditions is expected over the weekend. 

...HISPANIOLA...

Strong subsidence is noted on water vapor imagery over the 
island. The latest visible satellite imagery showed locally 
broken to overcast low clouds with possible embedded showers
mainly over the southwest portion of the island. Little change in
overall conditions is expected through the weekend.

ATLANTIC OCEAN...

A large complex middle to upper-level low is centered over the 
north-central Atlantic supports a cold front that enters the 
discussion area near 31N80W to 29N81W. Minimal shower activity 
is on either side of the front. To the east, a 1021 mb high is
located near 29N61W. A weakening cold front extends from 31N41W to
27N49W, then it transitions to a surface trough from that point 
to 24N59W. A pre-frontal trough extends from 32N37W to 24N44W. No
significant convection is observed with these features at this
time. The remainder of the basin is dominated by a surface ridge,
anchored by a 1022 mb high near 23N37W. Expect for the front and 
troughs over the central Atlantic to dissipate during the next 24 
hours. The cold front over the west Atlantic will continue moving 
east.
