The City of Yellowknife has announced the latest casualty of the warm weather: Frame Lake's ice.
Ice on the lake, specifically near the Co-op underpass, is now too thin for both pedestrians and snowmobilers.
Residents are urged to exercise caution on the lake as temperatures increase.
"Signs of weak ice include water covering the ice and a change in ice colour from clear to milky," wrote the City in a statement.
"Areas around protruding rocks or objects should also be avoided."

This is not Wednesday's first melting-ice warning issued for the Yellowknife area.
In the morning, the Department of Infrastructure warned the ice road connecting Yellowknife and Dettah could close within the next 24 hours due to "rapidly deteriorating conditions."
Ice roads and spring events have been closing early for the past month as record temperatures were set across the NWT.
