Weather Bulletin
TROPICAL STORM ISAAC WATCH STATEMENT
6 AM THURSDAY, SEPTEMBER 13, 2018
THIS IS FOR ST KITTS AND NEVIS
TROPICAL STORM FORCE WINDS NEARING THE LEEWARD
ISLANDS.
GUSTY CONDITIONS EXPECTED THROUGHOUT TODAY.
A TROPICAL STORM WATCH REMAINS IS EFFECT FOR ST KITTS
AND NEVIS.
A TROPICAL STORM WATCH MEANS THAT TROPICAL STORM
CONDITIONS ARE POSSIBLE IN THE SPECIFIED AREA, IN THIS
CASE WITHIN A FEW HOURS.
AT 0500 AM AST (0900 UTC), THE CENTER OF TROPICAL STORM
ISAAC WAS LOCATED NEAR LATITUDE 15.4 NORTH, LONGITUDE
59.7 WEST OR 238 MILES EAST-SOUTHEAST OF ST KITTS AND
NEVIS.
ISAAC IS MOVING TOWARD THE WEST NEAR 17 MPH (31 KM/H),
AND THIS GENERAL MOTION IS FORECAST TO CONTINUE FOR
THE NEXT SEVERAL DAYS. ON THE FORECAST TRACK, ISAAC IS
FORECAST TO MOVE ACROSS THE CENTRAL LESSER ANTILLES
AND INTO THE EASTERN CARIBBEAN SEA LATER TODAY, AND
THEN MOVE ACROSS THE EASTERN AND CENTRAL CARIBBEAN
SEA THROUGH THE WEEKEND.
DATA FROM A NOAA HURRICANE HUNTER AIRCRAFT
INDICATE THAT THE MAXIMUM SUSTAINED WINDS ARE NEAR
45MPH (85 KM/H) WITH HIGHER GUSTS. LITTLE CHANGE IN
STRENGHT IS EXPECTED OVER THE NEXT SEVERAL HOURS AS
ISAAC MOVES THROUGH THE LEEWARD ISLANDS, GRADUAL
WEAKENING IS FORECAST AFTERWARDS.
TROPICAL-STORM-FORCE WINDS EXTEND OUTWARD UP TO 160
MILES TO THE NORTH OF THE CENTER.

DATA FROM THE AIRCRAFT INDICATE THAT THE MINIMUM
CENTRAL PRESSURE IS 1006 MB (29.71 INCHES).
BASED UPON THE LATEST INFORMATION, TROPICAL STORM
ISAAC IS WEAKENING AND MAY EVEN DEGENERATE INTO AN
OPEN TROUGH TOMORROW. NOTWITHSTANDING HOWEVER
THE EFFECTS FROM THIS SYSTEM WILL BE FELT OVER ST.
KITTS AND NEVIS DURING THE COURSE OF TODAY AND THE
TROPICAL STORM WATCH REMAINS IN EFFECT FOR OUR
ISLANDS. WIND GUSTS TO 35 MILES PER HOUR ARE POSSIBLE
WITH THE PASSAGE OF ISAAC. THIS MEANS THAT SMALL AND
LOOSE OBJECTS MUST BE SECURED.
RAINFALL TOTAL OF UP TO AN INCH IS POSSIBLE MAKING
NAVIGATION DIFFICULT AND IT IS POSSIBLE THAT FLOODING
ADVISORIES MAY BECOME NECESSARY
SEAS WILL DETERIORATE WITH A COMBINATION OF WIND
DRIVEN WAVES AND SWELLS PEAKING NEAR 3.7 METRES OR 12
FEET. SMALL CRAFT OPERATORS SHOULD STAY IN PORT AND
SEA BATHERS SHOULD AVOID THE BEACHES UNTIL ISAAC
EXITS THE AREA
THE NEXT ADVISORY WILL BE AT 11 AM.
