Narrative:
First officer (first officer) was flying. I was pilot monitoring. Coming from the east ny center descended us to 4100 ft. In daytime VFR conditions. Airport and runway were in sight and was cleared for the visual 24. Pilot flying set 3100 which is FAF for the ILS 24. He then maneuvered the aircraft for a left base for runway 24 outside of worex which is about a 7 mile final to allow for a stable approach and avoid the hill to the east. Once clear of the hill he started a descent to 3100 ft. As we reached approximately 3400 ft. MSL we received a terrain alert from the egpws. Both the pilot flying and pilot monitoring had discussed the terrain prior to descending and both had it in sight since it was daytime VMC conditions. After the alert the pilot flying disengaged the autopilot; added thrust and stopped descent and even climbed and immediately after doing this the alert went away and the crew was able to make a normal and stable approach. Due to rate of descent and proximity to the terrain the system alerted the crew. It was daytime VMC conditions and the crew was able to maintain terrain clearance and the alert quickly extinguished. Crew could have either had a slower descent rate or waited to start down a bit later; or we could have asked to be vectored onto the ILS.
