Freezing rain warnings remain in effect for all counties of P.E.I., making roads "extremely hazardous," according to Environment Canada.
The national weather service updated the warnings late Saturday morning.
"Freezing rain will become a mix of snow and ice pellets this afternoon or early this evening," it said.
Drivers are urged to use caution.
"Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and extremely hazardous," Environment Canada said.
Deteriorating weather caused an early closure of the COVID-19 testing site in Slemon Park on Saturday, according to Health P.E.I. It will reopen Monday at 8 a.m.
Rain warning issued earlier for all three counties have ended.
