Rescue crews resumed their search for a 29-year-old swimmer on Lake Norman Monday morning.
Search teams set up a staging area on Charter Place in Mooresville Sunday. Charlotte Fire Department's dive team was also called in to help with the search.
One of the challenges in the search is the murky water in Lake Norman, according to Scott Strickland with the North Carolina Wildlife Resources Commission.
Sunday afternoon, there were four people on the boat when the missing swimmer jumped off with two other people. The boat wasn't anchored and started to float away. The three tried to swim and catch up with the boat, but the missing man wasn't able to make it back to the boat.
"One of the subjects wasn't able to get back to the vessel, and was having difficulty swimming with the current and the wind," Strickland said.
Shirley and Glenn Palehonki were on the water when the rescue began.
"We were on jet skis and it was very very rough. We saw some rescue boats out with red lights going around," said Shirley Palehonki.
Witnesses say the missing man went underwater shortly after trying to swim back to the boat. Officials say strong winds and currents are to blame for him not coming back up.
Glenn Palehonki says he was struggling to ride on his jet ski, and he cannot imagine how anybody was able to swim in the choppy waters.
"It gets rough like that, but not very often. Today was extremely windy and rougher than normal," he said.
Despite the use of sophisticated equipment and skilled divers, the search was suspended around 9:30 p.m. Sunday because of the dark. The search resumed at 8:30 a.m. Monday.
