Thanks to Karen for sending the photo! Amid the unsettled weather mixing sun and showers, sailboats were in view off Duwamish Head. While the U.S. Coast Guard Notice to Mariners shows several races/regattas around Puget Sound today, the only one listed in this area is the Corinthian Yacht Club‘s Center Sound Series Race #2. Third race in the series is in two weeks, on April 2nd.
ADDED: Another photo, sent by Stephen:
