AT 5 AM ECT OR 0900 UTC THE CENTRE OF TROPICAL STORM FIONA WAS LOCATED NEAR LATITUDE 16.6 NORTH, LONGITUDE 53.0 WEST OR ABOUT 586 MILES EAST OF ANGUILLA.
FIONA IS MOVING TOWARD THE WEST AT 13 MILES PER HOUR. THIS GENERAL MOTION IS EXPECTED TO CONTINUE DURING THE NEXT FEW DAYS. ON THE FORECAST TRACK, THE CENTRE OF FIONA IS EXPECTED TO MOVE THROUGH THE LEEWARD ISLANDS LATE FRIDAY AND FRIDAY NIGHT, AND BE NEAR THE VIRGIN ISLANDS THIS WEEKEND.
SATELLITE- DERIVED WIND DATA INDICATE THAT MAXIMUM SUSTAINED WINDS HAVE INCREASED TO NEAR 50 MPH WITH HIGHER GUSTS. SOME SLOW STRENGTHENING IS POSSIBLE OVER THE NEXT FEW DAYS.
TROPICAL STORM FORCE WINDS EXTEND UP TO 140 MILES EAST OF THE CENTRE.
THE ESTIMATED MINIMUM CENTRAL PRESSURE IS 1002 MB OR 29.59 INCHES.
BASED UPON THE LATEST OBSERVATION AND ANALYSIS, TROPICAL STORM CONDITIONS ARE POSSIBLE ACROSS PORTIONS OF THE NORTHERN LEEWARD ISLANDS BY FRIDAY.
