TROPICAL CYCLONE INFORMATION STATEMENT
ANTIGUA AND BARBUDA METEOROLOGICAL SERVICES
7:10 PM ECT TUESDAY SEP 26 2023
…TROPICAL STORM PHILIPPE COULD PASS RELATIVELY CLOSE TO THE ISLANDS…
…TROPICAL DISTURBANCE AL91 TO BECOME A TROPICAL CYCLONE AND PASS NEAR THE AREA…
THE ANTIGUA AND BARBUDA METEOROLOGICAL SERVICES CONTINUES TO FOLLOW THE
PROGRESS OF TROPICAL STORM PHILIPPE (FEE-LEEP) AND TROPICAL DISTURBANCE AL91
TROPICAL STORM PHILIPPE
CONFIDENCE IS NOW RELATIVELY LOW ON THE EVENTUAL PATH OF TROPICAL STORM PHILIPPE.
THE SYSTEM COULD NOW PASS MUCH CLOSER TO THE ISLANDS THAN INITIALLY FORECAST;
HOWEVER, STILL AT A SAFE DISTANCE AWAY FROM THE NORTHEAST CARIBBEAN. STILL, AT THE
REASONABLE WORST-CASE SCENARIO, THE SYSTEM POSES LITTLE TO NO WIND THREAT TO THE
LEEWARD ISLANDS AND THE BRITISH VIRGIN ISLANDS. HOWEVER, THERE IS A MODERATE
THREAT OF ABOVE-NORMAL SWELLS, WHICH HAVE THE POTENTIAL TO CAUSE SIGNIFICANT
IMPACTS AND LIFE-THREATENING NEARSHORE CONDITIONS.
AT 5 PM ECT OR 2100 UTC, THE CENTRE OF TROPICAL STORM PHILIPPE WAS LOCATED NEAR
LATITUDE 17.1 NORTH, LONGITUDE 51.3 WEST OR ABOUT 686 MILES EAST OF THE LEEWARD
ISLANDS MOVING WEST AT 13 MPH. A WEST TO WEST-NORTHWEST TRACK IS EXPECTED OVER
THE NEXT FEW DAYS.
MAXIMUM SUSTAINED WINDS ARE NEAR 45 MPH WITH HIGHER GUSTS. GRADUAL WEAKENING
IS FORECAST DURING THE NEXT FEW DAYS.
BASED ON THE FORECAST MODEL TRACKS, THE CENTRE OF TROPICAL STORM PHILIPPE IS NOW
FORECAST TO PASS A FEW HUNDRED MILES NORTH OF THE ISLANDS; HOWEVER, NO
HAZARDOUS WINDS ARE FORECAST TO REACH ANY OF THE ISLANDS.
NO TROPICAL CYCLONE ALERTS, WATCHES OR WARNINGS ARE IN EFFECT, AT THIS TIME;
HOWEVER, AN ALERT IS POSSIBLE, IF THE SYSTEM WERE TO TRACK MORE WEST THAN NORTH
AND SHOW SIGNS OF STRENGTHENING, WATCHES AND WARNING COULD BE REQUIRED IN THE
NEXT 12 TO 24 HOURS.
TROPICAL DISTURBANCE AL91
TROPICAL DISTURBANCE AL91 IS EXPECTED TO BECOME A TROPICAL CYCLONE IN 48 HOURS.
THERE IS NOTABLE UNCERTAINTY IN THE FORECAST TRACK OF THE CYCLONE THAT IS EXPECTED
TO FORM FROM THIS SYSTEM WITH SOME TRACKS BRINGING IT NEAR OR OVER THE AREA.
HOWEVER, AT THIS TIME, AT THE REASONABLE WORST-CASE SCENARIO, THE EXPECTED
TROPICAL CYCLONE POSES LITTLE TO NO THREAT TO THE LEEWARD ISLANDS AND THE BRITISH
VIRGIN ISLANDS.
AT 5 PM ECT OR 2100 UTC, THE CENTRE OF TROPICAL DISTURBANCE AL91 WAS LOCATED ABOUT
1631 MILES EAST-SOUTHEAST OF THE LEEWARD ISLANDS MOVING WEST-NORTHWEST AT
AROUND 15 MPH.
MAXIMUM SUSTAINED WINDS ARE NEAR 35 MPH WITH HIGHER GUSTS. THERE IS AN 80 PERCENT
CHANCE OF FORMATION TO A TROPICAL CYCLONE IN 48 HOURS AND A 90 PERCENT CHANCE OF
FORMATION IN SEVEN DAYS. THE SYSTEM IS LIKELY TO BECOME TROPICAL STORM RINA (REE-
NUH)
BASED ON THE FORECAST MODEL TRACKS, THE CENTRE OF WHAT IS LIKE TO BE RINA COULD BE
NEAR THE AREA OVER THE WEEKEND OR EARLY NEXT WEEK. HAZARDS, IF ANY, ARE HIGHLY
UNCERTAIN, AT THIS TIME.
NO TROPICAL CYCLONE ALERTS, WATCHES OR WARNINGS ARE IN EFFECT, AT THIS TIME;
HOWEVER, EITHER THIS SYSTEM OR PHILIPPE COULD TRIGGER ONE OR MORE IN THE COMING
DAYS.
RESIDENTS SHOULD CONTINUE TO MONITOR TROPICAL STORM PHILIPPE AND TROPICAL
DISTURBANCE AL91. ALL ARE ALSO STRONGLY ENCOURAGED TO STAY PREPARED FOR THE REST
OF THE HURRICANE SEASON.
THE NEXT UPDATE WILL BE GIVEN BY 5 PM TOMORROW, OR SOONER, IF REQUIRED.
