Tropical Storm Ophelia pummeled Long Island's South Shore Saturday causing what officials described as extremely rough rip currents.

Officials in Jones Beach State Park said the wave crest was about 8 to 10 feet offshore and about 3 to 4 feet on the shore.

Ophelia also impacted shore conditions at Robert Moses and Hither Hills in Montauk. Walls of sand were erected to protect the infrastructure.

These conditions also affected over 2,300 athletes who came out to Jones Beach for Long Island's inaugural Ironman competition. One participant told News 12 swimming conditions were rough in Zacks Bay. The participant described the bike course as brutal with the rain continuously pelting them.

News 12 was told 90 lifeguards were in Zachs Bay for the swimming portion. They were going to use drones but could not fly them due to the high winds.
