Model Recounts Horrifying Experience Being Swept Up by the Waves

Model Petra Nemcova says she still talks to boyfriend Simon Atlee -- months after the Indian Ocean tsunami nearly killed her and swept away the British photographer.

"I talk to Simon, I write to him," Nemcova told ABC News' Diane Sawyer in a special episode of "Primetime Live."

"I never used to write a diary. But now I'm writing a diary to him," she said. "I think it's not just me, but lots of others, family and friends, can still feel him around."

Nemcova, 25, and Atlee, 33, were in the Thai resort of Khao Lak on Dec. 26 when one of the deadliest tsunamis in modern history hit. Areas of Asia and Africa were flooded, and more than 200,000 people are believed to have died
