The 17 year old has been missing since entering the Swilly from Rathmullen Pier in the early hours of Saturday morning.
Weather conditions are hampering the movements of lifeboats and the coastguard helicopter
Volunteers are gathering on both sides of the Swilly for a low water shoreline search this afternoon.
They are being urged to wear proper outdoor clothing, equip themselves well and ensure that they stay in groups and tell the search coordinators where they are at all times.

Fr Martin Collon is Parish Priest in Rathmullen, and has paid tribute to local people and people from Derry who have been supporting the Mc Nair family and searchers over the past number of days.
Speaking to Greg Hughes on today's Shaun Doherty Show, he also paid tribute to the emergency and support services, saying what he has seen in the past few days has been an eye opener..........
