The council previously said the blowdown procedure – a technique previously used on Glasgow’s famed Red Road flats – had been “carefully selected” from a number of options.
A local drop-in respite facility will be available at Our Lady of Good Aid Cathedral/Firpark Primary School Campus on Milton Street until about 17:00 for residents who wish to use it.
Draffen Tower was completed in 1969, while the Allan and Coursington Towers were finished a year later in 1970.
Each one stands about 58m (190ft) tall and contained 117 flats, all of which are now abandoned.
The demolition forms part of a 25-year plan by North Lanarkshire Council to knock down all 48 high-rise blocks across the local authority area.
The local authority intends to build about 5,000 new homes to replace the tower blocks.
Housing convener Michael McPake previousy said: “This is a significant milestone in our commitment to building a better future for Motherwell.
“We will continue to work closely with the community to ensure a safe and smooth process.”
