Rainfall, combined with melting snow, is expected. The frozen ground has a reduced ability to absorb this rainfall.
A soaker on tap Saturday.
A moisture laden low from Texas will spread rain across Eastern Ontario overnight into Saturday, with most areas receiving a total of 20 to 30 mm by Saturday evening. The rain is then expected to change over to freezing rain Saturday evening as temperatures slide down to the zero degree mark.
Since the ground is frozen, the winter rainfall warning criterion of 25 mm in 24 hours is being met.
For information concerning flooding, please consult your local conservation authority or Ontario Ministry of Natural Resources and Forestry district office.
Freezing rain may last for several hours Saturday night before becoming mixed with ice pellets or a couple cm of snow Sunday. Significant ice accretion of 10 to 20 mm is possible Saturday night from the freezing rain. Freezing rain warnings will likely be issued as this event draws closer.
Brisk northerly winds Sunday are also possible. These winds coupled with ice build up on tree branches and power lines could cause a few power outages.
Warnings will be issued as the event draws nearer.
Travel will be impacted throughout Southern Ontario Saturday into Sunday.
If visibility is reduced while driving, turn on your lights and maintain a safe following distance. Localized flooding in low-lying areas is possible.
Rainfall warnings are issued when significant rainfall is expected.
