TROPICAL CYCLONE ALERT STATEMENT
ANTIGUA AND BARBUDA METEOROLOGICAL SERVICES
2:45 PM ECT SAT SEP 18 2021
…TROPICAL DISTURBANCE AL95 COULD BECOME A TROPICAL CYCLONE AND AFFECT THE AREA…
A TROPICAL CYCLONE ALERT IS IN EFFECT FOR THE LEEWARD ISLANDS AND THE BRITISH VIRGIN ISLANDS. A TROPICAL CYCLONE ALERT MEANS THAT, IN THIS CASE, A TROPICAL DISTURBANCE WITH OVER A 50 PERCENT CHANCE OF BECOMING A TROPICAL CYCLONE IS IN OUR MONITORED AREA. WATCHES AND WARNINGS ARE NOT REQUIRED AT THIS TIME BUT MAY BE REQUIRED IN THE NEXT 24 HOURS.
GIVEN THE CONTINUED FORECAST UNCERTAINTIES REGARDING AL95, WITH RESPECT TO TIME OF FORMATION, EVENTUAL TRACK, SIZE AND INTENSITY, IT IS NOT YET POSSIBLE TO SAY WITH HIGH CONFIDENCE WHAT EXACTLY WILL BECOME OF THIS SYSTEM. NOTWITHSTANDING, AT THE REASONABLE WORST-CASE, TROPICAL DISTURBANCE AL95 POSES AN ELEVATED THREAT WITH THE POTENTIAL TO CAUSE LIMITED IMPACTS FROM STORM-FORCE WINDS, HIGH SEAS AND MINOR FLOODING, RESULTING IN LIFE-THREATENING CONDITIONS, SOME DISRUPTIONS TO DAILY LIFE AND MINOR DAMAGE TO INFRASTRUCTURE. TO BE SAFE, BE PREPARED TO IMPLEMENT YOUR HURRICANE SEASON DISASTER PLANS, AT SHORT NOTICE.
AT 2 PM ECT OR 1800 UTC, THE CENTRE OF TROPICAL DISTURBANCE AL95 WAS LOCATED ABOUT 740 MILES EAST-SOUTHEAST OF THE LEEWARD ISLANDS MOVING WEST-NORTHWEST AT 15 MPH.
MAXIMUM SUSTAINED WINDS ARE NEAR 25 MPH WITH HIGHER GUSTS. NOTWITHSTANDING UNFAVOURABLE WIND SHEAR, GRADUAL DEVELOPMENT IS FORECAST AND THE SYSTEM HAS A 90 PERCENT CHANCE OF BECOMING A TROPICAL CYCLONE IN 48 HOURS.
ON ITS FORECAST TRACK, THE SYSTEM WILL LIKELY AFFECT THE AREA LATE SUNDAY OR MONDAY. HOWEVER, THERE IS STILL ENOUGH TIME FOR IT TO SHIFT FURTHER NORTH AND SPARE THE ISLANDS.
RESIDENTS SHOULD CONTINUE TO CLOSELY MONITOR TROPICAL DISTURBANCE AL95 AND HAVE THEIR HURRICANE SEASON DISASTER PLANS PREPARED TO SAFEGUARD LIFE, PROPERTY AND LIVELIHOOD, IN THE EVENT WATCHES OR WARNINGS ARE ISSUED, SOMETIME IN THE NEXT 24 HOURS.
THE NEXT UPDATE WILL BE AROUND 9 PM THIS EVENING OR SOONER, IF REQUIRED. STAY TUNED TO UPDATES COMING OUT OF THE ABMS MET OFFICE VIA ANTIGUAMET.COM, HOTLINE: 463-4638, FACEBOOK.COM/ABMETSERVICE AND TWITTER.COM/ABMETSERVICE. ALSO, STAY TUNED TO ABS TV AND RADIO ALONG WITH OTHER MEDIA PLATFORMS FOR UPDATES.
