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...METEOROLOGICAL ANALYSIS...WEATHER
OBSERVATIONS...AND RADAR.
BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1645 UTC.
...ITCZ...
THE ITCZ AXIS IS CENTERED ALONG 7N9W 6N22W 3N35W 8N48W 11N53W
10N63W. ISOLATED MODERATE CONVECTION IS FROM 4N-7N BETWEEN
18W-25W. SIMILAR ACTIVITY IS FROM 2N-5N BETWEEN 26W-35W...AND
FROM 6N-8N BETWEEN 40W-47W. A SURFACE TROUGH EXTENDS FROM 18N49W
TO 9N51W. ISOLATED MODERATE CONVECTION IS TO THE E OF THE AXIS
FROM 10N-18N BETWEEN 43W-49W.
...DISCUSSION...
GULF OF MEXICO...
AS OF 1500 UTC...A 1013 MB LOW IS LOCATED S OF THE FLORIDA
PANHANDLE NEAR 30N86W. A WARM FRONT EXTENDS TO THE E ALONG
31N83W 31N81W. A COLD FRONT EXTENDS TO THE SE FROM THE LOW
CENTER ALONG 28N85W TURNING S-SW ALONG 26N86W 24N89W BECOMING
STATIONARY TO 21N93W. MOST OF THE SHOWER ACTIVITY LIES BETWEEN
THESE TWO FRONTS. RADAR IMAGERY INDICATES SHOWERS/THUNDERSTORMS
ALONG A SWATH FROM 26N84W ACROSS TAMPA INTO CENTRAL FLORIDA NEAR
27N81W. A SECOND SWATH OF STRONGER SHOWERS/THUNDERSTORMS EXTENDS
FROM 28N84W INTO THE BIG BEND OF FLORIDA TO NEAR 30N82W.
ISOLATED SHOWERS/THUNDERSTORMS ARE WITHIN 100 NM OF THE
STATIONARY FRONT AND ELSEWHERE BETWEEN THE WARM FRONT AND
STATIONARY FRONT AFFECTING MUCH OF FLORIDA. AN OCCLUDED FRONT
EXTENDS W FROM THE LOW CENTER TO A SECOND 1013 MB LOW OVER ERN
LOUISIANA NEAR 31N90W. A SURFACE TROUGH EXTENDS FROM THIS LOW
ALONG 29N91W 27N95W. IN THE UPPER LEVELS...MOIST SWLY FLOW
EXTENDS ACROSS MUCH OF THE GULF AROUND A BROAD UPPER LEVEL
TROUGH OVER THE CENTRAL CONUS. AN UPPER LEVEL LOW IS EMBEDDED IN
THE LONGWAVE TROUGH CENTERED OVER TENNESSEE SUPPORTING THE LOW
PRESSURE AND FRONTAL SYSTEM. A SLOT OF DRY AIR EXTENDS OVER SE
TEXAS AND THE NW GULF. EXPECT THE LOW PRESSURE SYSTEM TO MOVE NE
AS THE FRONTAL SYSTEM MOVES E...AND BOTH ARE EXPECTED TO WEAKEN
OVER THE NEXT 24 HRS. SHOWERS/THUNDERSTORMS ARE EXPECTED OVER
THE ERN GULF OF MEXICO AS THE LOW/FRONTAL SYSTEM PUSHES E.
CARIBBEAN SEA...
SIGNIFICANT DRY AIR AND SUBSIDENCE IS ACROSS THE CARIBBEAN
NOTED IN WATER VAPOR IMAGERY SUPPORTING FAIR WEATHER ACROSS MUCH
OF THE BASIN. A FEW SHOWERS/THUNDERSTORMS ARE S OF HISPANIOLA
FROM 17N-18N BETWEEN 70W-74W ASSOCIATED WITH A SURFACE TROUGH N
OF HISPANIOLA IN THE ATLC. SCATTERED SHOWERS/THUNDERSTORMS ARE
ALSO ACROSS THE SW CARIBBEAN S OF 12N BETWEEN 79W-85W. THIS
ACTIVITY IS ENHANCED BY SURFACE CONVERGENCE NEAR THE E PACIFIC
ITCZ...AS WELL AS DIFFLUENT FLOW ALOFT BETWEEN AN UPPER LEVEL
TROUGH SW OF CENTRAL AMERICA AND A BROAD UPPER LEVEL RIDGE THAT
COVERS THE CARIBBEAN. MODERATE TO FRESH TRADEWINDS ARE ACROSS
MUCH OF THE BASIN WITH STRONGER WINDS IN THE ERN CARIBBEAN AND
NEAR THE COAST OF COLOMBIA. EXPECT LITTLE CHANGE OVER THE NEXT
24 HRS.
ATLANTIC OCEAN...
ISOLATED SHOWERS EXTEND INTO THE FAR WRN ATLC FROM ACROSS
FLORIDA N OF 27N W OF 75W ASSOCIATED WITH A WARM FRONT EXTENDING
ACROSS NRN FLORIDA TO NEAR 30N80W. A WEAK 1014 MB SURFACE LOW IS
NEAR 31N73W WITH A SURFACE TROUGH EXTENDING TO NEAR 29N76W.
SHOWERS ARE POSSIBLE NEAR THE LOW CENTER. AN UPPER LEVEL RIDGE
COVERS THE WRN ATLC KEEPING THE REMAINDER OF THE AREA UNDER FAIR
CONDITIONS...EXCEPT FOR AN AREA OF SHOWERS/THUNDERSTORMS ACROSS
THE SE BAHAMAS FROM 20N-22N BETWEEN 70W-73W. THIS ACTIVITY IS
ENHANCED BY SURFACE CONVERGENCE NEAR A SURFACE TROUGH THAT
EXTENDS ALONG 30N59W S TO 25N62W SW ALONG 23N67W TO NRN
HISPANIOLA NEAR 20N73W. ISOLATED SHOWERS ARE ALSO WITHIN 200 NM
E OF THE TROUGH AXIS N OF 25N. FARTHER E...A SURFACE TROUGH
EXTENDS FROM 30N50W TO 25N48W. SCATTERED SHOWERS/THUNDERSTORMS
ARE WITHIN 150 NM OF THE TROUGH AXIS. A SECOND SURFACE TROUGH
EXTENDS FROM THE FAR ERN ATLC ALONG 31N11W 29N22W 27N33W 30N43W.
ISOLATED SHOWERS ARE ALONG THE AXIS...AND N OF 21N BETWEEN
40W-45W. SCATTERED SHOWERS/THUNDERSTORMS ARE N OF THE TROUGH
AXIS FROM 30N-33N BETWEEN 33W-40W. THIS SERIES OF TROUGHS AND
ASSOCIATED SHOWER ACTIVITY IS SUPPORTED BY AN UPPER LEVEL TROUGH
IN THE CENTRAL ATLC FROM 26N44W TO 12N51W. DIFFLUENT FLOW
BETWEEN THIS TROUGH AND AN UPPER LEVEL RIDGE DIRECTLY TO THE N
OF THE TROUGH IS ALSO ENHANCING THE SHOWER ACTIVITY. ZONAL WLY
FLOW IS ACROSS THE TROPICAL
ATLC.

CENTER WILL MAINTAIN FRESH TO STRONG TRADES FROM 08N TO 24N W OF
117W. WHILE THE PRIMARY SWELL DIRECTION WILL CONTINUE FROM THE
NW...NE WINDS WILL GENERATE WIND WAVES THAT MIX WITH THE NW
SWELL. THE STRONGEST TRADES WILL BE FROM 14N TO 18N W OF 135W
WHICH WILL PRODUCE COMBINED SEAS OF 12 FT. THE STRONGEST REGION
OF LOW LEVEL CONFLUENCE IN THE ITCZ IS W OF 118W WHERE MODERATE
TO FRESH SE WINDS S OF THE ITCZ CONVERGE WITH FRESH TO LOCALLY
STRONG NE TRADES N OF THE ITCZ...WHICH HAS RESULTED IN MORE
ACTIVE CONVECTION.

PRODUCE 20 KT TO OCCASIONAL 25 KT WINDS IN THE GULF OF FONSECA
AND PAPAGAYO...WITH THE STRONGER WINDS IN THE OVERNIGHT AND
MORNING HOURS DUE TO DRAINAGE FLOW ENHANCING THE WINDS. AS
INDICATED IN THE LATEST SCATTEROMETER PASSES...WINDS HAVE
DIMINISHED OVER THE GULF OF TEHUANTEPEC. WINDS WILL PICK UP
AGAIN TODAY AS WINDS BEHIND THE COLD FRONT IN THE GULF OF MEXICO
FLOW THROUGH THE PASS. FRESH TRADEWINDS WILL CONTINUE TO FLOW
THROUGH THE GULF OF PANAMA FOR THE NEXT 24 HOURS...THEN WILL
DIMINISH.

FIELD WILL CONTINUE TO PROVIDE POSSIBLE ISOLATED SHOWERS
THROUGHOUT THE AFTERNOON AND EVENING HOURS OVER THE NE CARIBBEAN.
ATLANTIC OCEAN...
AN UPPER LEVEL SHORTWAVE TROUGH LOCATED OVER THE NE CONUS AND
EASTERN CANADA SUPPORTS A DISSIPATING STATIONARY FRONT THAT
PASSES THROUGH 32N76W TO NEAR CAPE CANAVERAL AND INTO THE SE
GULF OF MEXICO. A SURFACE TROUGH EXTENDS FROM A 1014 MB LOW
NEAR 31N75W TO 28N74W ACROSS THE CENTRAL BAHAMAS TO 23N78W WITH

NEAR 28N94W IN 24 HOURS WITH NEAR GALE FORCE WINDS AND
CONVECTION.
CARIBBEAN SEA...
MODERATE TO FRESH TRADEWINDS DOMINATES THE BASIN. PATCHES OF
BROKEN TO OVERCAST LOW CLOUDS DOTS THE CARIBBEAN AND CENTRAL
AMERICA NAMELY OVER PUERTO RICO...HISPANIOLA...NEAR THE CAYMAN
ISLANDS FROM 19N-21N BETWEEN 82W-86W...THE SW CARIBBEAN W OF
80W...AND INLAND FROM BELIZE S TO PANAMA. THE ITCZ ALSO
TRAVERSES NORTHERN SOUTH AMERICA FROM TRINIDAD TO N COLOMBIA TO
PANAMA WITH BROKEN TO BROKEN MULTILAYERED CLOUDS AND ISOLATED
MODERATE CONVECTION. A SURFACE TROUGH IS OVER THE WINDWARD
ISLANDS PRODUCING SHOWERS E OF 64W. IN THE UPPER LEVELS...THE
CARIBBEAN IS EXPERIENCING GENERALLY FAIR WEATHER UNDER THE
INFLUENCE OF DRY AIR AND SUBSIDENCE N OF 10N. UPPER LEVEL
MOISTURE IS S OF 10N DUE TO THE ITCZ. EXPECT... SHOWERS/
THUNDERSTORMS TO CONTINUE OVER THE SW CARIBBEAN OVER THE NEXT 24
HOURS. ALSO EXPECT...SIMILAR CONVECTION OVER THE WINDWARD
ISLANDS AS THE SURFACE TROUGH DRIFTS W OVER THE NEXT 24 HOURS.
ATLANTIC OCEAN...
A STATIONARY FRONT IS OFF THE COAST OF N FLORIDA ALONG 32N78W
28N80W. A SURFACE TROUGH...THE REMNANTS OF IDA IS OVER THE W
ATLANTIC ALONG 27N58W 20N62W. SCATTERED SHOWERS ARE WITHIN 30 NM
OF THE TROUGH AXIS. A SECOND SURFACE TROUGH IS FURTHER E ALONG
23N43W 18N45W. SCATTERED SHOWERS ARE WITHIN 60 NM OF THE TROUGH
AXIS. A THIRD SURFACE TROUGH IS OVER THE CENTRAL ATLANTIC ALONG
23N34W 18N37W. SCATTERED SHOWERS ARE WITHIN 60 NM OF THIS TROUGH
AXIS. THE TAIL END OF A COLD FRONT IS OVER THE CENTRAL ATLANTIC
FROM 32N32W TO 30N40W. A STATIONARY FRONT CONTINUES W ALONG
29N48W 30N60W. A 1021 MB HIGH IS CENTERED OVER THE E ATLANTIC
NEAR 36N10W. A RIDGE AXIS EXTENDS SW FROM THE HIGH TO SW OF THE
CANARY ISLANDS NEAR 26N22W.

TROPICAL WEATHER DISCUSSION FOR THE EASTERN PACIFIC OCEAN FROM
THE EQUATOR TO 32N...EAST OF 140W.
BASED ON 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
2100 UTC.
...ITCZ...
AXIS IS ALONG 4N77W 6N90W 7N105W 5N120W 8N140W. SCATTERED
MODERATE CONVECTION WITHIN 100 NM S OF AXIS FROM 107W-110W.
SCATTERED MODERATE TO STRONG CONVECTION WITHIN 60 NM EITHER SIDE
OF AXIS W OF 136W.
...DISCUSSION...
AN UPPER LEVEL TROUGH IS APPROACHING THE FAR NW PORTION OF THE
DISCUSSION AREA. OTHERWISE A BROAD UPPER LEVEL RIDGE COVERS THE
AREA W OF 110W. THE RIDGE AXIS EXTENDS FROM AN ANTICYCLONIC
CIRCULATION CENTERED NEAR 11N118W N TO 32N134W...ANOTHER RIDGE
EXTENDS FROM THE ANTICYCLONIC CIRCULATION NE TO 16N107W. A
90-105 KT JET STREAM ENTERS THE AREA AT 24N140W TO 26N125W THEN
SE ACROSS SOUTHERN TIP BAJA CALIFORNIA THEN INTO CENTRAL MEXICO.
MODERATE TO STRONG SUBSIDENCE WITH DRY STABLE AIR AT THE MIDDLE
AND UPPER LEVELS IS N OF THE JET. BROKEN TO OVERCAST HIGH CLOUDS
ARE WITHIN 600 NM S OF THE JET AXIS FROM 140W-130W. DOWNSTREAM
MID/UPPER LEVEL TROUGH EXTENDS FROM A CYCLONIC CIRCULATION OVER
THE SOUTHERN ROCKIES ACROSS NW MEXICO TO THROUGH SOUTHERN BAJA
PENINSULA. AN UPPER LEVEL TROUGH E OF THE ANTICYCLONIC
CIRCULATION IN THE DEEP TROPICS WITH AXIS FROM 15N102W TO
4N113W. UPPER LEVEL DIFFLUENT FLOW IS ENHANCING CONVECTIVE
ACTIVITY ALONG THE ITCZ AND A SURFACE TROUGH FROM 6N-9N BETWEEN
107W-110W. OTHERWISE MODERATE TO STRONG SUBSIDENCE S OF 15N E OF
120W HAS SUPPRESSED CONVECTION ALONG THE ITCZ IN THIS AREA.
THE PRES GRADIENT HAS WEAKENED ACROSS SOUTHERN MEXICO AND THE
WINDS HAVE DECREASED TO 20-25 KT IN THE GULF OF TEHAUNTEPEC AND
WILL CONTINUE TO DECREASE THROUGH THE NEXT 24 HOURS. A 1023 MB
SURFACE HIGH PRES CENTERED NEAR 31N130W IS PRODUCING STRONG
ENOUGH GRADIENT FOR WINDS TO REACH 20 TO 25 KT FROM 10N TO 21N W
OF 120W. BROKEN TO OVERCAST STRATOCUMULUS CLOUDS COVER THE AREA
N OF 20N BETWEEN 115W-135W.
A SURFACE TROUGHS IS ANALYZED ALONG THE ITCZ FROM 14N109W TO
5N110W. SCATTERED MODERATE CONVECTION IS FROM 6N-9N BETWEEN
107W-110W.
