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
0810 UTC.
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH AXIS ENTERS THE ATLANTIC NEAR THE COAST OF
GUINEA-BISSAU AT 11N15.5W AND EXTENDS SOUTHWESTWARD 05N22W. THE
ITCZ CONTINUES FROM 05N22W TO THE COAST OF BRAZIL AT 02N51W.
WIDELY SCATTERED MODERATE CONVECTION IS ONGOING FROM 01N TO 06N
EAST OF 21W, AND ALSO FROM 01N TO 09N BETWEEN 23W AND 49W.
..GULF OF AMERICA
A STATIONARY FRONT EXTENDS FROM NEAR TAMPA BAY, FLORIDA TO NEAR
THE TEXAS MEXICO BORDER JUST SOUTH OF BROWNSVILLE. SOME ISOLATED
TO WIDELY SCATTERED SHOWERS ARE POSSIBLE NEAR AND NORTH OF THE
FRONT. WINDS ARE MODERATE OR WEAKER ACROSS THE BASIN, HIGHEST OFF
THE YUCATAN AND SOUTH TEXAS COASTS. SEAS ARE 2 TO 4 FT OFF THE
SOUTH TEXAS COAST AND YUCATAN, AND 3 FT OR LESS ELSEWHERE. LIGHT
SMOKE FROM AGRICULTURAL AND FOREST FIRES OVER SOUTHERN MEXICO
COVERS MOST OF THE BASIN.
FOR THE FORECAST, THE STATIONARY FRONT WILL LINGER TODAY WHILE
GRADUALLY WASHING OUT. GENTLE TO MODERATE WINDS WILL DOMINATE THE
BASIN THROUGH THIS MORNING. WINDS OVER THE WESTERN ZONES WILL
GRADUALLY STRENGTHEN THIS AFTERNOON AND EVENING TO MODERATE TO
FRESH, THEN TO FRESH TO STRONG LATER TONIGHT THROUGH WED MORNING.
WINDS WILL PULSE TO MODERATE TO FRESH IN THE STRAITS OF FLORIDA
THROUGH MID- WEEK. ANOTHER WEAK FRONT MAY REACH THE NW GULF MID-
WEEK. SMOKE FROM AGRICULTURAL FIRES IN SOUTHEASTERN MEXICO IS
CREATING HAZY CONDITIONS IN SOME SECTIONS OF THE WESTERN GULF,
WITH THE LOWEST REPORTED VISIBILITY NEAR THE SW GULF COAST.
..CARIBBEAN SEA
SCATTERED SHOWERS THUNDERSTORMS ARE NOTED BETWEEN EASTERN JAMAICA
AND HAITI JUST SOUTH OF THE WINDWARD PASSAGE, OTHERWISE NO
CONVECTION IS PRESENT IN THE BASIN. MODERATE TRADES PREVAIL ACROSS
THE CENTRAL CARIBBEAN, AS WELL AS IN THE NW CARIBBEAN WEST OF
85W. SEAS ARE 2 TO 4 FT, EXCEPT 2 FT OR LESS IN THE LEE OF CUBA.
FOR THE FORECAST, MODERATE TO FRESH EAST TO SOUTHEAST WINDS WILL
PULSE NORTH OF HONDURAS, INCREASING TO FRESH TO STRONG SPEEDS
NIGHTLY STARTING TUE NIGHT. UNSETTLED WEATHER IS EXPECTED TO
CONTINUE OVER MOST OF THE EASTERN CARIBBEAN WELL INTO THE WEEK.
GENTLE TO MODERATE TRADES AND SLIGHT TO MODERATE SEAS ARE EXPECTED
OVER THE REMAINDER OF THE BASIN THROUGH THE PERIOD, INCLUDING IN
THE TROPICAL N ATLANTIC, PULSING TO FRESH NIGHTLY NEAR THE
WINDWARD PASSAGE STARTING TONIGHT.
..ATLANTIC OCEAN
THE PRESSURE GRADIENT BETWEEN A TROUGH THAT EXTENDS FROM 27N59W
TO 20N56.5W AND A RIDGE OF HIGH PRESSURE OVER THE WESTERN ATLANTIC
IS SUPPORTING FRESH TO LOCALLY STRONG NORTHEAST WINDS AND SEAS TO
LOCALLY ROUGH NORTH EAST OF THE AXIS. THE RIDGE IS ANCHORED BY A
1029 MB HIGH PRESSURE WELL NORTH OF THE AREA NEAR 37N47W. A COLD
FRONT IS EAST AND SOUTHEAST OF THESE FEATURES, REACHING FROM NORTH
OF 31N27W TO 27N44W. ANOTHER FRONT IS WELL TO THE WEST, ALONG AND
JUST OFF THE COAST FROM NEAR CHARLESTON, SOUTH CAROLINA TO NEAR
DAYTONA BEACH, FLORIDA. WINDS ACROSS THE TROPICAL ATLANTIC ARE
MAINLY MODERATE OR WEAKER AWAY FROM THE SURFACE TROUGH IN THE
CENTRAL WATERS, WHILE WINDS JUST NORTH OF 31N AHEAD OF THE FRONT
OFF THE SE UNITED STATES ARE FRESH TO STRONG THERE. SEAS ARE
MAINLY 3 TO 6 FT AWAY FROM THE CENTRAL WATERS TROUGH, SLIGHTLY
HIGHER SOUTH AND SOUTHWEST OF THE CABO VERDE ISLANDS.
FOR CONVECTION, SOME SCATTERED SHOWERS AND EMBEDDED THUNDERSTORMS
ARE POSSIBLE AHEAD OF THE FRONT OFF THE SE U.S., NORTH OF 30N AND
WEST OF 70W TO THE FRONT. WITH THE CENTRAL WATERS TROUGH,
SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ARE WITHIN 300 NM
SOUTHEAST, EAST, AND NORTHEAST OF THE AXIS.
FOR THE FORECAST WEST OF 55W, THE MARINE CONDITIONS ASSOCIATED
WITH THE SURFACE TROUGH IN THE EASTERN SW N ATLANTIC ZONES WILL
GRADUALLY SHIFT WESTWARD THROUGH THE EARLY PART OF THE WEEK AS THE
TROUGH DRIFTS WESTWARD. A STATIONARY FRONT ALONG THE SOUTHEASTERN
U.S. COAST WILL GRADUALLY LIFT BACK NORTHWEST AS WARM FRONT
THROUGH THE MIDDLE OF THE WEEK, THEN MAY SLOWLY PUSH OFFSHORE
AGAIN AT THE END OF THE WEEK. EXPECT SCATTERED TO NUMEROUS SHOWERS
AND THUNDERSTORMS OVER THE WESTERN WATERS INTO THE EARLY PART OF
THE WEEK.
