LU said in a statement: "To ensure the safe operation of the network, it will be necessary to get trains back to depots before strike action commences."
LU added the services may not return to normal until Friday morning.
It said the Jubilee, Northern and Piccadilly lines, which are maintained by Tube Lines, would be running.
Another 72-hour stoppage is planned for Monday.
'No guarantees'
The Jubilee, Northern and Piccadilly lines, which are maintained by the other maintenance company Tube Lines, would be running, it said.
The RMT said the Tube network would "grind to a halt" as a result of the industrial action.
A spokesman said any problems with the maintenance of trains, tracks or signalling would not be resolved.
"If anything goes wrong, it will stay wrong," he said.
Copper-bottomed guarantees
On Monday, Unite and the TSSA said they would not go on strike after being given assurances.
But the TSSA said its 360 members would take part in the second 72-hour strike on Monday, if a matter concerning pensions was not resolved.
The unions have been seeking guarantees there will be no job losses, forced transfers or cuts in pensions as a result of Metronet's collapse in July, when it went into administration.

Unite said on Monday its 500 members would not be going on strike.
RMT general secretary Bob Crow said the union had not received the "copper-bottomed guarantees" it had been seeking.
Regional officer Brian Harris said: "After days of intense negotiations we're pleased to announce that Unite is calling off its industrial action at Metronet."
The Transport Salaried Staffs Association (TSSA) said its 360 members would not be going ahead with a strike planned for Tuesday.
However, it said its members would take part in the second 72-hour strike next Monday if a matter concerning pensions was not resolved later this week.

RMT general secretary Bob Crow said: "There has been no contact over the weekend from Metronet or the administrator so as far as we are concerned the strike will definitely go ahead."
He said the union had not received the "copper-bottomed guarantees" it had been seeking.
The only assurances received so far were related to jobs and transfers and covered only the period of administration, he added.
He warned of a second 72-hour strike on 10 September if the issue was not resolved.

A spokesman said services would still run, but any problems with maintenance of trains, tracks or signalling would not be repaired.
The only assurances received so far were related to jobs and transfers and covered only the period of administration, he said.
"If anything goes wrong, it will stay wrong," he said.
Transport for London said it had released copies of letters sent to the unions making it clear there would be no job losses, forced transfers or changes to pensions while Metronet was in administration.
London Mayor Ken Livingstone has said all Metronet employees were given written assurances there would be no reduction in jobs or transfers of employees from Metronet.
Mayor of London Ken Livingstone said: "It would be incomprehensible to disrupt the lives of millions of Londoners and lose their members significant amounts of pay when all of the assurances they have asked for have been given."
Mr Livingstone also said staff had been assured their pensions would be fully protected.
He said: "It would be incomprehensible to disrupt the lives of millions of Londoners and lose their members significant amounts of pay when all of the assurances they have asked for have been given."
Dan Hodges, Director of TfL, said: "We have been asking RMT to tell us what further guarantees they require to avert this dispute.
"We have been waiting since Sunday afternoon and have still received no communications from them."
