Environment Canada expects what's left of former Hurricane Beryl will sweep into parts of southern Ontario later this week.
Now a tropical storm, by the time Beryl reaches the province it will have been reduced to a big bag of water.
"Confidence in the track of the weather system and associated rainfall amounts is low at this point," Environment Canada said in a special weather statement issued on Monday afternoon. The rainfall advisory covers a wide swath from portions of Musoka south to the Greater Toronto area, west to Grey County and east to Haliburton.
Forecasters say torrential downpours could give rainfall rates of 20 to 40 mm per hour at times with localized rainfall totals possibly well in excess of 50 mm.
The rain is expected to begin late Tuesday night or Wednesday, and continuing into Thursday.
"These types of systems in the past have given very high rainfall rates in torrential downpours," according to Environment Canada.
Beryl blasted into the Texas coast on Monday morning as a Category 1 hurricane but quickly dropped to a tropical depression, unleashing heavy rain and killing at least three people as it moved east. Power was cut to about 3 million homes and businesses, and it could take several days to restore power.
The storm was far less powerful than the Category 5 behemoth that tore a deadly path of destruction through parts of Mexico and the Caribbean last weekend. But the winds and rains of the fast-moving storm were still powerful enough to knock down hundreds of trees that had already been teetering in water-saturated earth, and strand dozens of cars on flooded roadways.
