Whitecaps made whale-watching difficult Thursday morning off Fauntleroy, but a northbound group of 10 or more orcas was reported in the ferry lanes.

Shortly after 10 a.m., Kersti Muul said fins were hard to pick out in the choppy water. About a quarter-hour later, the group was reported to be nearing Constellation, with repeated blows still visible despite the rough surface.

The sighting came the morning after a windstorm, when glare and chop can make dark shapes on the water harder to identify. In those conditions, the tall exhale of a blow can stand out more clearly than a fin.
