The bitterly cold weather that currently has much of the East Coast of America in its icy grip has demonstrated its chilling intensity by partially freezing Niagra Falls for the second time in just weeks.
Remarkable images taken of the falls at night show them partially frozen and lit up in an array of bright colours. The falls on the American side, which in combination with the Bridal Veil Falls usually see the passage of 567,811 Litres per second, have frozen amid temperatures of -1 degrees and lower.
Temperatures in the area fell to -23C with wind chill last week bringing the rushing waters to an icy standstill.
The US East Coast is currently in the grip of a deadly winter storm that has seen near-record temperature lows, around 3,000 flights cancelled and the mass closure of schools and local government buildings.
