Weather
During takeoff roll; we received a windshear alert at approximately 90 kts. We rejected our takeoff. After accomplishing our checklists and checking our brake temps; we taxied back and attempted a second takeoff. We received another windshear alert at approximately 100 kts and rejected again. We accomplished the checklist items and checked brake temps again. We attempted a third takeoff and were able to takeoff with no issues.
A widebody McDonnell Douglas crew rejected two takeoffs between 90-100 KTS after GPWS windshear warnings. The third takeoff was successful.
