IMAGERY, WEATHER OBSERVATIONS, RADAR AND METEOROLOGICAL ANALYSIS.
BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1035 UTC.
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH AXIS ENTERS THE ATLANTIC NEAR 12N16W AND
EXTENDS SOUTHWESTWARD TO 05N21W. THE ITCZ STRETCHES FROM 05N21W TO
00N49W. SCATTERED MODERATE CONVECTION IS PRESENT SOUTH OF 05N AND
WEST OF 25W.
..GULF OF AMERICA
A COLD FRONT IS MOVING ACROSS THE NW GULF OF AMERICA, EXTENDING
FROM SW LOUISIANA TO NE TAMAULIPAS. A STRONG SQUALL IS NOTED AHEAD
OF THE FRONT, PRODUCING WIND GUSTS TO GALE FORCE, FREQUENT
LIGHTNING STRIKES AND HIGHER SEAS. MODERATE TO FRESH NORTHERLY
WINDS AND MODERATE SEAS ARE FOUND BEHIND THE FRONT. GENERALLY DRY
CONDITIONS ARE EVIDENT IN THE REMAINDER OF THE BASIN. MODERATE TO
FRESH SE WINDS AND SLIGHT TO MODERATE SEAS ARE PRESENT SOUTH OF
26N AND EAST OF 94W. ELSEWHERE, LIGHT TO GENTLE WINDS AND SLIGHT
TO MODERATE SEAS PREVAIL.

EASTWARD TODAY, WITH A LOW DEVELOPING ALONG THE FRONT NEAR SE
LOUISIANA. THE LOW WILL MEANDER OVER THE NE GULF THROUGH SUN WHILE
THE FRONT WILL MOVE EASTWARD ACROSS THE WESTERN HALF OF THE

NORTHERLY WINDS AND MODERATE TO ROUGH SEAS ARE EXPECTED IN THE
WAKE OF THE FRONT THROUGH SAT NIGHT. SEAS TO 9 FT ARE EXPECTED FRI
NIGHT INTO SAT MORNING IN THE SW GULF. SMOKE FROM AGRICULTURAL
FIRES IN SOUTHEASTERN MEXICO IS CREATING HAZY CONDITIONS IN PARTS
OF THE GULF REGION.
..CARIBBEAN SEA
HIGH PRESSURE NORTH OF THE CARIBBEAN SUPPORTS FRESH TO STRONG
EASTERLY WINDS IN THE GULF OF HONDURAS, ALONG WITH SEAS OF 3-6 FT.
MODERATE TO FRESH NE-E WINDS ARE PRESENT IN THE CENTRAL CARIBBEAN,
INCLUDING THE WINDWARD PASSAGE. SEAS IN THESE WATERS ARE ALSO 3-6

..ATLANTIC OCEAN
A SURFACE TROUGH EXTENDS NORTH TO SOUTH ALONG A WEAK 1013 MB LOW
PRESSURE NEAR 26N67W. ANOTHER SURFACE TROUGH IS NOTED NORTH OF THE

RIDGE TO THE NORTH AND THE AFOREMENTIONED TROUGHS SUSTAIN
MODERATE TO FRESH SE-E WINDS AND MODERATE TO ROUGH SEAS NORTH OF
