A January thaw could lead to localized problems, especially in urban areas, but is not expected to cause significant flooding in the Grand River watershed. However, conditions around rivers, streams, lakes and ponds will be dangerous the next few days. People should stay away from banks, and keep their children and pets away. Also, stay off  ice-covered rivers, streams and ponds where some melting may weaken ice surfaces.

Temperatures are forecast to rise throughout today (Friday) and overnight, peaking at about 6C early Saturday. The warmer weather will also bring about 15 mm of rain. Temperatures will drop through Saturday and Sunday to around 0C, but rebound on Monday with some more rain.

 

 

There is a lot of snow on the ground, particularly in Waterloo Region, Wellington County and Dufferin County and most rivers and streams are covered with ice. However, based on current forecasts, there’s won’t be enough warm weather to cause significant melting. Much of the rain will be soaked up by the snow already on the ground.

Still, GRCA staff will be keeping a close eye on the rivers in case there is some ice breakup and ice jams develop. Ice jams could lead rapidly to localized flooding. In urban areas, some street flooding is possible where catch basins are covered with snow and ice. In addition, some urban streams could be blocked at culverts and bridges by moving ice and tree debris, causing flooding. The warm spell is expected to end Monday with a return to more seasonable temperatures.

GRCA staff will be keeping a close eye on the situation and issue updates as required.
