Narrative:

Hurricane bertha was approaching from the south with a line of storms approximately 20 mi south of airport. Conditions at the airport were a 200 ft ceiling, visibility 3/4 mi in moderate rain, wind 090 degrees at 20 KTS, temperature 73 degree F, and altimeter 29.79 inches. We departed runway 9L. There were no windshear reports prior to our takeoff. As soon as the main wheels left the ground, the windshear warning in the cockpit activated. Firewall power was called for and the first officer called out vertical speed and airspeed readings. Aircraft flew out of windshear in approximately 10 seconds and power was reduced. We continued to original destination as the WX was much better there, and engines were operating normally. I wrote up the engines in the logbook and maintenance found no damage.
