The New South Wales south east is expected to swelter through extreme heat today.
The Bureau of Meteorology is predicting temperatures to reach 43 degrees in the Eurobodalla, while the far south coast, Monaro and high country are expected to reach the mid-30s.
Forecaster, Bec Kamitakahara says there will also be strong winds blowing across the region.
She says the weather could trigger devastating bushfires.
"For some parts of the region, it's going to be an absolute scorcher, particularly along the northern parts of the south coast,â?? Ms Kamitakahara said.
â??Batemans Bay for example is going for 43 degrees.
â??That 43 is a constant right along the coast, all the way up to Sydney.
â??Further south, the temperatures will be a more moderate 35 and 30 at Bega and Merimbula," she said.
Ms Kamitakahara says people need to be prepared.
"It will be extremely windy and with that high temperature and those stronger winds that is creating extremely dangerous fire conditions.
â??The south and the east of New South Wales will see widespread severe fire danger with the potential for some districts to reach extreme."
