Narrative:

During vectors to ILS 36 about 5 miles west of myr at 2;000 ft we received a GPWS oral warning 'whoop; whoop; pull up; terrain terrain' we were IMC so we performed the escape maneuver and climbed to about 3;500 ft and informed ATC. I checked our altimeters which were correct and there was no terrain in the area that could have triggered the GPWS. We continued the approach and landing.
