TROPICAL STORM EARL DISCUSSION NUMBER  42

500 PM EDT SAT SEP 04 2010

LARGE TROPICAL CYCLONE EARL HAS BEEN MOVING TOWARD THE
NORTH-NORTHEAST AT ABOUT 35 KNOTS PRODUCING SUSTAINED TROPICAL
STORM FORCE WINDS OVER MUCH OF THE CANADIAN MARITIMES. THE
CYCLONE IS BECOMING A LITTLE BIT ASYMMETRIC AND THE WIND FIELD IS
EXPANDING...BUT THERE IS PLENTY OF ORGANIZED CONVECTION NEAR THE
CENTER FOR SUCH A HIGH LATITUDE CYCLONE. THIS MEANS THAT EARL STILL
IS RETAINING ITS TROPICAL CHARACTERISTICS.  THE CYCLONE IS FORECAST
TO MOVE OVER THE COLD WATERS OF THE GULF OF SAINT LAWRENCE AND
BECOME POST-TROPICAL LATER TONIGHT.
