TROPICAL WEATHER DISCUSSION
NWS NATIONAL HURRICANE CENTER MIAMI FL
0615 UTC SAT MAY 10 2025
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 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0600 UTC.
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH AXIS ENTERS THE ATLANTIC THROUGH THE COAST OF
GUINEA NEAR 09N13W AND EXTENDS SOUTHWESTWARD TO 06N15W, WHERE IT
TRANSITIONS TO THE ITCZ. THE ITCZ THEN CONTINUES TO 01N50W.
SCATTERED MODERATE AND ISOLATED STRONG CONVECTION IS OBSERVED FROM
01-07N BETWEEN 09-37W. MORE SCATTERED MODERATE CONVECTION IS ALSO
OBSERVED FROM THE EQUATOR TO 04N BETWEEN 37-50W.
GULF OF AMERICA...
AT 0000 UTC, A 1008 MB LOW PRESSURE WAS CENTERED NEAR 29N90W. A
COLD FRONT EXTENDS FROM THE LOW CENTER TO THE SOUTH-CENTRAL BAY OF
CAMPECHE. A WIDE BAND OF SHOWERS AND THUNDERSTORMS, WITH GUSTY
WINDS TO GALE FORCE, IS IN THE NE GULF AHEAD OF THE FRONT AND N OF
27N. A SWATH OF FRESH TO STRONG N TO NW WINDS AND SEAS OF 4-8 FT
FOLLOW THE FRONT. AHEAD OF THE FRONT, SE WINDS ARE MODERATE TO
FRESH WITH SEAS OF 2-5 FT.
FOR THE FORECAST, A COLD FRONT EXTENDS FROM A 1008 MB LOW PRES
NEAR 29N90W TO THE SOUTHERN COAST OF THE BAY OF CAMPECHE NEAR
18N95W. STRONG STORMS ARE AFFECTING THE NE GULF WATERS, PRODUCING
GUSTY WINDS AND FREQUENT LIGHTNING. FRESH TO STRONG N WINDS WILL
CONTINUE TO AFFECT MUCH OF THE WESTERN GULF THROUGH EARLY SAT.
HOWEVER, THE MOST PERSISTENT STRONG WINDS WILL CONTINUE OFF
VERACRUZ INTO SAT AFTERNOON. LOCALLY ROUGH SEAS MAY ACCOMPANY
THESE WINDS, ESPECIALLY NEAR TAMPICO AND VERACRUZ. WINDS WILL
DIMINISH BY EARLY SUN. FARTHER EAST, LOW PRESSURE LOOKS TO
STRENGTHEN IN THE EASTERN GULF ON SAT, PRODUCING FRESH TO STRONG
WINDS SURROUNDING THE LOW AS IT MOVES NORTHEASTWARD THROUGH THE
BASIN INTO EARLY NEXT WEEK.
CARIBBEAN SEA...
ISOLATED MODERATE CONVECTION IS OCCURRING IN THE FAR SW CARIBBEAN
S OF 12N AND W OF 73W, IN THE VICINITY OF THE EAST PACIFIC MONSOON
TROUGH. SCATTERED MODERATE CONVECTION IS ALSO OCCURRING IN THE NW
CARIBBEAN W OF 86W AHEAD OF A COLD FRONT MOVING ACROSS THE GULF OF
AMERICA. OTHERWISE, THE PRESSURE GRADIENT BETWEEN RIDGING N OF THE
CARIBBEAN AND THE COLOMBIA LOW SUPPORTS MODERATE TO FRESH TRADES
ACROSS THE CENTRAL CARIBBEAN, WITH LOCALLY STRONG WINDS OCCURRING
OFFSHORE NW COLOMBIA. MODERATE TO FRESH NE WINDS ARE ALSO
OCCURRING THROUGH THE WINDWARD PASSAGE, PER RECENT SCATTEROMETER
DATA. GENTLE TO MODERATE TRADES PREVAIL ELSEWHERE. SEAS IN THE
CENTRAL CARIBBEAN ARE 4-7 FT, WITH 3-5 FT SEAS ELSEWHERE.
FOR THE FORECAST, BUILDING RIDGE NORTH OF THE AREA WILL SUPPORT
FRESH TO STRONG NE-E WINDS AND ROUGH SEAS ACROSS MUCH OF THE
CENTRAL CARIBBEAN THROUGH EARLY NEXT WEEK. THE STRONGEST WINDS AND
HIGHEST SEAS WILL OCCUR OFF NW COLOMBIA. ELSEWHERE, A MODERATE
PRESSURE GRADIENT WILL SUSTAIN FRESH TO LOCALLY STRONG E WINDS IN
THE GULF OF HONDURAS TONIGHT AND SAT NIGHT. FRESH TO LOCALLY
STRONG NE WINDS WILL ALSO PULSE THROUGH THE WINDWARD PASSAGE INTO
EARLY NEXT WEEK.
ATLANTIC OCEAN...
A WEAK 1016 MB LOW PRESSURE IS ANALYZED NEAR 27N68W. NO
SIGNIFICANT WEATHER IS NEAR THIS LOW. A DISSIPATING COLD FRONT IS
APPROACHING THE CANARY ISLANDS IN THE FAR EAST ATLANTIC, FOLLOWED
BY STRONG NW WINDS AND 9-12 FT SEAS. THE REMAINDER OF THE
ATLANTIC FORECAST REGION IS UNDER THE INFLUENCE OF A 1033 MB HIGH
PRESSURE LOCATED NEAR 39N47W. THIS SYSTEM SUPPORTS MODERATE TO
FRESH TRADES AND MODERATE SEAS ACROSS MUCH OF THE ATLANTIC E OF
60W. GENTLE TO MODERATE WINDS AND SEAS OF 3-6 FT PREVAIL W OF 60W.
FOR THE FORECAST WEST OF 55W, THE PRESSURE GRADIENT BETWEEN A
SURFACE TROUGH ALONG A WEAK 1016 MB LOW PRESSURE NEAR 27N64W AND A
BUILDING RIDGE IN THE CENTRAL ATLANTIC RESULT IN MODERATE TO
FRESH E-SE WINDS AND MODERATE TO LOCALLY ROUGH SEAS EAST OF 65W.
WINDS AND SEAS WILL DIMINISH THIS WEEKEND AS THE RIDGE BUILDS IN.
FARTHER WEST, MODERATE TO FRESH SE WINDS ARE FORECAST TO DEVELOP
OFFSHORE OF FLORIDA AND THE BAHAMAS BY SAT NIGHT AHEAD OF A COLD
FRONT MOVING THROUGH THE EASTERN GULF OF AMERICA. LOOKING AHEAD,
STRONG S WINDS MAY DEVELOP OFFSHORE OF NORTHERN FLORIDA EARLY NEXT
WEEK AS THE AFOREMENTIONED COLD FRONT MOVES INTO THE WESTERN
ATLANTIC. THE MARINE CONDITIONS WILL IMPROVE BY MIDWEEK.
