4:03 PM: SFD, SPD, and the U.S. Coast Guard are all reported to be on the way to check into reports of a windsurfer in trouble 50 to 100 yards off Lowman Beach/north Lincoln Park. The windsurfer is reported to have been having trouble getting back up on their board.

4:11 PM: Police have been scanning the water from land and told dispatch they see windsurfers – including one with a blue-green sail as the 911 caller described – but none appear to be in distress. A USCG boat has arrived in the area and will check further.

4:18 PM: The SPD and SFD units on land are ending their response, concluding that there’s no sign of trouble, while the USCG unit verifies with the windsurfer if they indeed are not in need of assistance.
