While you're pulling on yet another jumper, spare a thought for Sydney - which has been sweltering its way through the hottest day on record - as temperatures reach nearly 46C.

According to the Bureau of Meteorology the temperature is significantly higher than the 39 degrees it had originally forecast because an expected breeze has not moved onto the coast from the sea.

Yet the Sydney Morning Herald reports that just hours after registering the sizzling high, a severe weather warning was issued for the city.

Heavy rain and damaging winds are apparently on the way, with warnings also in place for the NSW Central Tablelands and parts of the Hunter, Illawarra and Central West Slopes and Plains Forecast Districts.
