30/21Z Update: Earl is now a Category IV Hurricane with sustained winds of 115 knots (135mph) - still moving to the west northwest at 12 knots. At 5PM Earl was located 110 miles to the northeast of San Juan, Puerto Rico. Additional intensification is still a good possibility within the next 24 hours - perhaps as high as 130 knots (150mph) and maybe even a little more before windshear begins to stabilize and then slowly reduce the winds.

Extended movement to the west northwest for yet another 24 hours or so before Earl turns more to northwest, the official track has been adjusted more to the left. Folks in the Turks & Caicos, the Bahamas, along the east coast of the United States and northward to the Canadian Maritimes need to keep a close watch for any additional track adjustments on this major hurricane, since the northward influence of the Atlantic trough extending southwestward to about 25N 68W has not been, so far, as significant as originally anticipated.
