Emergency Management Commissioner Andrew Crisp said the Bureau of Meteorology had issued a severe weather warning for the eastern half of the state.

"We are seeing a number of new fires start as a result of lightning strikes, some up near the Dargo fire, also near Mount Wellington. So we are not out of this yet," he told ABC Radio.

"As we know we've seen some of these warnings move up and down over last couple of days, it's so important for everyone to stay tuned into our broadcasters or the app to make good decisions."

He said the wild weather will continue for the next 36-48 hours.
