In its HURRICANE EARL ADVISORY NUMBER 28, the National Hurricane Centre estimated the location of the centre of Hurricane Earl to be near 24.0N 71.2W or ABOUT 175 MI...280 KM N OF GRAND TURK ISLAND. MAXIMUM SUSTAINED WINDS were 125 MPH...205 KM/HR and the MOVEMENT was to the NW OR 310 DEGREES AT 16 MPH...26 KM/HR. MINIMUM CENTRAL PRESSURE was 941 MB...27.79 INCHES.
Hurricane Earl at about 3:45 a.m. EDT on 1 Sep 2010.
While Hurricane Earl is passing quite close to the Turks and Caicos and to the Southeastern Bahamas, effects have been much less than might otherwise have been expected due to the presence of southwesterly shear, which is limiting convection and wind speeds in the SW quadrant. This is fortunate, since according to the NHC, ...THE CORE OF THE HURRICANE WILL BE PASSING . . . EAST AND NORTHEAST OF THE BAHAMAS TODAY AND TONIGHT...
While tropical storm warnings have been discontinued for the Southeast Bahamas and for the Turks and Caicos, there is a warning up for San Salvador. Because HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 90 MILES...150 KM...FROM THE CENTER...AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 200 MILES...325 KM, San Salvador can expect some sustained tropical storm force winds and potentially heavy rainfall today. However, nearby islands like Cat Island and Long Island are likely to experience mostly squally weather with occasional gusts to tropical storm force.
The NW Bahamian islands like Eleuthera, Abaco, and Grand Bahama can expect similar squally weather throughout the day, but unless SW shear lessens radically in the next 12 hours not much more.
Tropical Storm Fiona is currently centred just east of the NE Lesser Antilles, where Earl produced heavy rains and hurricane force winds earlier this week. While forecasts suggest Fiona will also turn to the NW and then north before it approaches the Bahamas, local meteorologists are continuing to monitor its progress.
