Ottawa is set to receive a soaking from Mother Nature, with up to 40 mm of rain possible over the next two days.
Environment Canada has issued a rainfall warning for Ottawa and eastern Ontario, calling for rain, heavy at times, tonight and on Wednesday.
“Rain, at times heavy, will start this evening. Rain may taper off on Wednesday morning, but it is expected to intensify again on Wednesday afternoon,” the weather agency said in a statement.
“Total rainfall amounts of 30 to 40 mm are possible by Wednesday evening before rain changes to snow as temperatures drop below the freezing mark. Given the frozen ground, significant amounts of water due to snowmelt and rain could accumulate on roads and low-lying areas.”

A freezing drizzle advisory also remains in effect for Ottawa, with periods of freezing drizzle expected to continue until noon.
