Brisbane Region manager for State Emergency Service (SES) Mark Dole said people need to start planning now for potential flooding and storms.
Earlier this year, the Bureau of Meteorology said the chances of a La Nina forming in the coming months is three times more likely than normal.
Mr Dole said people should consider including elderly neighbours or relatives in the plan.
The Queensland Government has provided emergency plan templates to help Queenslanders with the planning process on their website.
