She undertook the stint on TV2 and broke the previous world record after 24 hours. She continued presenting and smashed the record with a final total of just over 33 hours, reported the BBC.
The record was broken in a glass TV studio at Domkirkeplassen Square in Oslo and Gjengedal can now boast of having hosted the world's longest-lasting weather forecast, said TV2 in a press release.
During the world record attempt, the 41-year-old was allowed to take a five-minute break for every 60 minutes she was on screen.
Gjengedal said to Dagbladet before her world record attempt: “This is a wet dream for a weather forecaster who is usually cut after two and a half minute on screen.”
“Finally we have enough time to forecast the weather for all the counties in Norway in a proper way. We are going to talk about every small valley this country got; we'll move out into the world and have a look at different weather phenomena. We will talk with other weather reporters around the world. This will be fun," she added.
Gjengedal continued: “I will forecast for as long I can stand it. Non-stop. Two meteorologists are going to sit beside me. We're going to analyse the weather and simply milk the world's biggest subject for conversation – the weather.”
After her mammoth weather report on Thursday, Gjengedal told the BBC she planned to "go out for a beer" to celebrate.
