Tropical Weather Discussion for North America, Central America
Gulf of America, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.
Based on 0600 UTC surface analysis and satellite imagery through 
0830 UTC.
...TROPICAL WAVES...
The axis of a tropical wave is near 24W, south of 20N, moving 
westward at 10 to 15 kt. Scattered moderate and isolated strong
convection is noted from 13N to 18N between 22W and 27W.
The axis of a tropical wave is near 63W, south of 20N and extends
into Guyana, moving westward at 15 kt. Limited convection is in 
the vicinity of the wave.
The axis of a tropical wave is near 73W, south of 19N, moving 
westward at 15 to 20 kt. Limited convection is in the vicinity of
the wave.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic near 18N16W, and continues
southwestward to near 10N40W. The ITCZ extends from 10N40W to 
09N59W. Aside from convection noted in the tropical waves section
above, scattered moderate and isolated strong convection is noted
from 06N to 13N E of 20W. Scattered moderate convection is noted
from 07N to 12N between 30W and 38W.
 
...GULF OF AMERICA...
A weak pressure gradient is over the discussion waters supporting
gentle to locally moderate winds. These winds are generating
mainly slight seas over the Gulf waters. 
For the forecast, weak high pressure will persist into early next
week, supporting mostly light to gentle winds and slight seas. 
Winds will pulse to fresh with moderate seas off the western 
Yucatan Peninsula during the evenings due to a diurnal surface 
trough moving westward from the peninsula each night.
...CARIBBEAN SEA...
The pressure gradient between high pressure N of the area 
and the Colombian low is supporting fresh to strong trade winds 
and rough seas over the south-central Caribbean. Gentle to
moderate winds, and slight too locally moderate seas, are over 
the NW Caribbean. Moderate to fresh winds and moderate seas cover 
the remainder of the Caribbean waters. 
For the forecast, the western Atlantic ridge extends E to W along
about 26N to the NW Bahamas. The pressure gradient between the
ridge and the Colombian low will support fresh to strong winds
through early next week. Moderate to rough seas will prevail over
these waters. Elsewhere, moderate or weaker winds and slight to 
moderate seas will prevail.
...ATLANTIC OCEAN...
A cold front enters the forecast region near 31N50W and continues
westward to near 28N60W where it becomes stationary to near 
29N70W. Scattered moderate convection is in the vicinity of the
front. Moderate to fresh winds are noted S of 25N and W of 50W.
Moderate to fresh winds are also over the far NE portion of the
discussion waters, in the vicinity of the Canary Islands eastward
toward the coast of Africa. Light to gentle winds dominate the
remainder of the discussion waters. Moderate seas prevail over
much of the area. 
For the forecast west of 55W, the cold front over the NE waters 
will shift east of the area today. High pressure ridging will 
build across the region in the wake of the front. Light to gentle 
winds are expected in the vicinity of the ridge, N of 21N. 
Moderate to fresh winds S of 21N will diminish slightly by this 
weekend.
