Newfoundland and Labrador Hydro crews were trying again Tuesday morning to reach a small community on Newfoundland's south coast, where many residents have been without power for two days.

Between 20 and 30 customers in La Poile, or about half of the community, lost their power early Sunday morning.

Officials say they will not know what caused the outage until crews arrive. Poor weather prevented air travel on Sunday and Monday.

A helicopter was scheduled to leave Bishops Falls on Tuesday morning, pick up a line crew in Burgeo and then head to La Poile.
