WITH SEVERE GUSTS ARE FORECAST IN THE IRVING HIGH SEAS FORECAST
ZONE UNTIL 09/0000 UTC. ROUGH TO VERY ROUGH SEAS MAY ACCOMPANY
THIS SYSTEM, ANCHORED BY A 1005 MB OCCLUDED LOW CENTERED NEAR
33N28W. FRESH TO STRONG W WINDS AND SEAS 8 FT OR MORE EXTEND
SOUTHWARD TO 28N BETWEEN 25W-35W. FOR MORE DETAILS, REFER TO THE

THE MONSOON TROUGH AXIS ENTERS THE ATLANTIC ALONG THE COAST OF
SENEGAL NEAR 13N17W AND EXTENDS SOUTHWESTWARD TO 04N28W. THE ITCZ
CONTINUES FROM 04N28W TO 02N49W. SCATTERED MODERATE ISOLATED STRONG
CONVECTION IS ONGOING FROM 02N-08N EAST OF 18W. SCATTERED MODERATE
CONVECTION IS NOTED FROM 00N-02N BETWEEN 38W-43W AND FROM 05N-09N
BETWEEN 46W-50W.
..GULF OF AMERICA
AS OF 2100 UTC, A DISSIPATED STATIONARY FRONT EXTENDS FROM THE
FLORIDA PANHANDLE TO THE TEXAS-MEXICO BORDER. NUMEROUS MODERATE
SCATTERED STRONG CONVECTION IS NOTED NORTH OF 25N WEST OF 90W. A
PRE-FRONTAL TROUGH IS ALSO ANALYZED FROM 28N87W TO THE FLORIDA BIG
BEND NEAR 29N83W. SCATTERED MODERATE CONVECTION IS OCCURRING
NORTH OF 28N EAST OF 87W. STRONG TO GALE FORCE GUSTS AND LARGE
STEEP WAVES ARE POSSIBLE IN THE VICINITY OF THESE THUNDERSTORMS.
AWAY FROM THE DEEP CONVECTION, WINDS ACROSS THE GULF ARE GENTLE TO
MODERATE WITH SEAS 2-5 FT.
FOR THE FORECAST, A FRONTAL BOUNDARY LOCATED OVER THE NORTHERN
GULF WILL CONTINUE TO DISSIPATE TONIGHT. A COLD FRONT IS CURRENTLY
REACHING THE NW GULF. THIS SYSTEM WILL BEGIN TO MOVE ACROSS THE
WESTERN GULF ON FRI, 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
BASIN. BY MON, THE LOW IS FORECAST TO MOVE NORTHWARD AND THE FRONT
WILL CONTINUE TO MOVE ACROSS THE EASTERN GULF. A BAND OF SHOWERS
AND THUNDERSTORM COULD BE ASSOCIATED WITH THE FRONT. FRESH TO
STRONG NORTHERLY WINDS AND MODERATE TO ROUGH SEAS ARE EXPECTED IN
THE WAKE OF THE FRONT THROUGH SAT NIGHT. SMOKE FROM AGRICULTURAL
FIRES IN SOUTHEASTERN MEXICO IS CREATING HAZY CONDITIONS IN PARTS
OF THE GULF REGION.

MODERATE TRADES ACROSS THE CARIBBEAN THIS AFTERNOON. SEAS ARE 2-4
FT. NO SIGNIFICANT DEEP CONVECTION IS OCCURRING THIS AFTERNOON

19N-25N BETWEEN 55W-60W. ANOTHER TROUGH IS ALONG 67W NORTH OF 24N
WITH A WEAK 1015 MB LOW CENTERED AT 26N67W. A MODERATE PRESSURE
GRADIENT BETWEEN THESE TWO TROUGHS AND A 1033 MB BERMUDA-AZORES
HIGH AT 41N47W IS CAUSING FRESH TO STRONG E TO NE WINDS NORTH OF

1034 MB LOCATED OVER THE CENTRAL ATLANTIC IS SUPPORTING FRESH TO
LOCALLY STRONG E TO SE WINDS AND MODERATE TO ROUGH SEAS NE OF THE
