NSW Rural Fire Service volunteers attached to brigades from Lavington to Lankeys Creek will be stationed at Penrith tomorrow, ready to respond to any fires that occur.
As a state of emergency was being declared by the NSW Premier Gladys Berejiklian on Monday morning, 11 Southern Border RFS volunteers forming a strike team were preparing to depart.
Southern Border Team district co-ordinator Andrew Gray said they were joining other RFS members.
"The state has made a collective of fire trucks they can spare to be available to respond short notice into the Blue Mountains and Sydney basin area," he said.
"They will be joining up with Murrumbidgee Irrigation Area, with seven vehicles in that strike team, and they'll also be joining a team from Cooma which is another seven vehicles.
"The deployment could be three to five days - three days at best, if there's no fires to go to."
Fire and Rescue NSW members from Albury, Corowa, and other parts of Southern NSW are also assisting.
