I suggest you get some heat to those pipes ASAP. An electric heater near where the pipes
enter the basement ceiling would be a start. You don't want them bursting.

iI will repeat. OPEN THE TAPS. If the pipes are going to split but
have not yet, opening the taps will prevent splitting in most cases.

Generally the pipe does not split where it is frozen - it splits
downstream because the water is pressurized beyond the capacity of the
pipe. The water is at it's "largest" just before it freezes. The ice
blocks the pipe, the water on both sides expands. On the "in" side it
"backs up" to the supply - on the "out" side it pressurizes against
the closed faucet and splits the pipe. You don't really know it's
split until it thaws and line pressure forces copious amounts of water
out of the split. Opening the tap prevents the pressure from building
and also reduces the flow out of the split when the plug thaws and you
turn the water back on.

Leaving a tap running even a WEE bit can prevent freezing, but also
prevent splitting if it does freeze.

And yes -0 it's -24C with a windchill of -34-ish up here in Ontario
right now - - -
