A TROPICAL STORM WARNING REMAINS IN EFFECT FOR ANTIGUA AND BARBUDA
Effective
22:45:16 2020-07-28
Expires

Description
A TROPICAL STORM WARNING REMAINS IN EFFECT FOR ANTIGUA AND BARBUDA. A TROPICAL STORM WARNING MEANS THAT TROPICAL STORMS CONDITIONS ARE EXPECTED SOMEWHERE WITHIN THE WARNING AREA WITHIN 36 HOURS.
POTENTIAL TROPICAL CYCLONE NINE PRESENTS A MODERATE THREAT WITH THE POTENTIAL TO CAUSE SIGNIFICANT IMPACTS FROM STORM-FORCE WINDS, ELEVATED STORM SURGE, EXTREME SEAS, MODERATE FLOODING AND POSSIBLY A FEW TORNADOES, RESULTING IN LIFE-THREATENING CONDITIONS, DISRUPTIONS TO DAILY LIFE AND SOME DAMAGE TO INFRASTRUCTURE. TO BE SAFE, IMPLEMENT YOUR TROPICAL STORM DISASTER PLAN.
AT 5 PM LST OR 2100 UTC, THE CENTRE OF POTENTIAL TROPICAL CYCLONE NINE WAS LOCATED NEAR LATITUDE 14.4 NORTH, LONGITUDE 55.9 WEST OR ABOUT 425 MILES EAST-SOUTHEAST OF ANTIGUA AND BARBUDA.
THE CYCLONE IS MOVING TOWARD THE WEST-NORTHWEST AT AROUND 23 MPH. THIS GENERAL MOTION WITH A SLIGHT REDUCTION IN FORWARD SPEED IS EXPECTED OVER THE NEXT FEW DAYS.
MAXIMUM SUSTAINED WINDS ARE NEAR 40 MPH WITH HIGHER GUSTS. SOME STRENGTHENING IS EXPECTED DURING THE NEXT 48 HOURS, AND THE SYSTEM IS FORECAST TO BECOME TROPICAL STORM ISAIAS TONIGHT OR WEDNESDAY.
ON THE FORECAST TRACK, TROPICAL-STORM-FORCE WINDS WILL MOST LIKELY REACH ANTIGUA AND BARBUDA WEDNESDAY MORNING, AFTER SUNRISE, BUT COULD BEGIN EARLIER. WINDS SHOULD SUBSIDE BY LATE WEDNESDAY; THE WHOLE EVENT SHOULD END BY WEDNESDAY NIGHT BAR THE CONTINUATION OF RAINFALL.
ALTHOUGH POTENTIAL TROPICAL CYCLONE NINE IS EXPECTED TO IMPACT THE ISLANDS AS A WEAK TROPICAL STORM WITH WINDS OF 40 TO 50 MPH, TO BE SAFE, PLANS AND PREPARATIONS SHOULD BE FOR THE REASONABLE WORST-CASE SCENARIO OF THE SYSTEM IMPACTING ANTIGUA AND BARBUDA WITH WINDS OF 50 TO 60 MPH. THUS, THE CYCLONE HAS THE POTENTIAL TO CAUSE SOME DAMAGE, POWER OUTAGE AND DISRUPTIONS TO TRAVEL – THE COUNTRY WILL MOST LIKELY BE FORCED TO CLOSE. NOTWITHSTANDING, A MORE WESTERLY TRACK COULD RESULT IN MINIMAL IMPACTS.
Instructions
RESIDENTS ARE URGED TO IMPLEMENT THEIR TROPICAL CYCLONE PLANS, AS THE SYSTEM POSES A MODERATE THREAT WITH THE POTENTIAL TO CAUSE DAMAGE AND INJURY OR LOSS OF LIFE.
