A mix of heavy rain, mild temperatures and melting snow could result in localized flooding throughout the GTA on Wednesday, Environment Canada says.

The entire region, along with most of southern and eastern Ontario, is under a special weather statement and a flood watch as a result.

Between 15 and 25 millimetres of rain are forecast to fall, beginning Tuesday night and into Wednesday. Thunderstorms are possible Wednesday afternoon and some areas may see even more rain by the time the system has moved through, Environment Canada says.

"The frozen ground has a reduced ability to absorb this rainfall," the federal weather agency says. "Localized flooding in low-lying areas and water pooling on roads is possible."

Daytime temperatures are expected to climb into the mid and high single digits today and tomorrow, and then remain above zero throughout the rest of the week.
