Right now might be a good time to just stay indoors. An Ontario storm is making its way overnight on Jan. 10 and it's going to hit hard. A rainfall or freezing rain warning is currently in effect for the entire southern Ontario region.\nAccording to The Weather Network, the rain is expected to be ridiculously heavy at some parts overnight on Friday and into the weekend.\nIt's expected to continue right into Saturday with an expected total of 40 to 60 millimetres of rainfall right into the evening.\nSome parts of Ontario are expected to be hit with record-breaking rainfalls which will see more than a month's worth of rain in just a few hours.\nUnsurprisingly, as a result, flood warnings are also in effect for the GTA. So, if you plan to head into the outdoors, make sure to be prepared.\nIn fact, the chance of severe flooding is so real that the City of Toronto tweeted an advisory on Friday evening of how to avoid your basement becoming a pond.\nAccording to TWN, there's a chance that the rain might transform into freezing rain starting on Saturday evening since temperatures are set to fall down to around zero degrees.\nEnvironment Canda\nWell, that sounds just delightful.\nAs if all that rain and freezing conditions weren't enough, 80 km/h winds are expected by Sunday morning.\nAccording to Environment Canada, over towards Ottawa, the rain warning is joined by a special weather statement warning of hazardous conditions caused by the precipitation flash-freezing.\nRainfall and freezing rain warning, winter storm watch and special weather statement in effect for Ontario South.
