THIS IS FOR ST KITTS AND NEVIS
TROPICAL STORM GRACE A LITTLE STRONGER…
CONDITIONS EXPECTED TO DETERIORATE IN THE LEEWARD ISLANDS LATER TODAY AND TONIGHT A TROPICAL STORM WARNING REMAINS IN EFFECT FOR ST. KITTS AND NEVIS.
A TROPICAL STORM WARNING MEANS THAT TROPICAL STORM CONDITIONS ARE EXPECTED WITHIN THE SPECIFIED AREA, IN THIS CASE, WITHIN 24 HOURS.
THEREFORE, RESIDENT ARE URGED TO IMPLEMENT THEIR HURRICANE PREPAREDNESS PLANS FOR A POTENTIALLY STRONG TROPICAL STORM. AT THE REASONABLE WORST-CASE SCENARIO, THE SYSTEM POSES A MODERATE THREAT, WITH THE POTENTIAL TO CAUSE SIGNIFICANT IMPACTS FROM STORM-FORCE-WINDS, HIGH SEAS AND MODERATE FLOODING, RESULTING IN LIFE-THREATENING CONDITIONS, DISRUPTIONS TO DAILY LIFE AND DAMAGE TO INFRASTRUCTURE. TO BE SAFE, START TO IMPLEMENT YOUR HURRICANE SEASON DISASTER PLANS FOR THE STORM.
AT 11 AM ECT OR 1500 UTC, THE CENTRE OF TROPICAL STORM GRACE WAS LOCATED NEAR LATITUDE 16.2 NORTH, LONGITUDE 57.9 WEST OR ABOUT 326 MILES EAST SOUTHEAST OF ST. KITTS AND NEVIS.
TROPICAL STORM GRACE IS MOVING QUICKLY TOWARD THE WEST NEAR 23 MPH (37 KM/H). THIS GENERAL MOTION IS EXPECTED TO CONTINUE WITH A GRADUAL DECREASE IN FORWARD SPEED EXPECTED DURING THE NEXT FEW DAYS. ON THE FORECAST TRACK, THE CENTRE OF THE STORM IS FORECAST TO MOVE OVER THE LEEWARD ISLANDS TONIGHT.
MAXIMUM SUSTAINED WINDS ARE NEAR 45 MPH WITH HIGHER GUSTS. SOME STRENGTHENING IS FORECAST DURING THE NEXT COUPLE OF DAYS.
TROPICAL STORM FORCE WINDS EXTEND UP TO 35 MILES FROM THE CENTRE. THE ESTIMATED MINIMUM CENTRAL PRESSURE IS 1005 MB OR 29.68 INCHES.
BASED UPON THE LATEST OBSERVATION AND ANALYSIS, THE TROPICAL STORM CONDITIONS WILL BEGIN TO AFFECT THE ISLANDS BETWEEN SATURDAY NIGHT THROUGH SUNDAY MORNING. PEAK WINDS OF 45 MPH ARE EXPECTED TO MOVE ACROSS ST. KITTS AND NEVIS WITH GUSTS TO NEAR 60 MPH. RAINFALL TOTALS IN EXCESS OF 2 INCHES ARE LIKELY AND COULD LEAD TO FLOODING IN LOW LYING AND FLOOD PRONE AREAS. RESIDENTS IN THESE AREAS SHOULD KEEP THIS IN MIND.
SEAS WILL START TO DETERIORATE BY TONIGHT WITH PEAK HEIGHTS OF 2.8 METERS OR 9 FEET. THEREFORE, MARINERS SHOULD STAY IN PORT AND SEEK SAFE ANCHORAGE.
ALL RESIDENTS ARE URGED TO MONITOR THE MOVEMENT OF TROPICAL STORM GRACE CLOSELY AND ACT TO PROTECT LIFE AND PROPERTY.
THE NEXT ADVISORY WILL BE AT 5 PM ECT.
