Major flooding in southwest Ontario and Michigan

A state of emergency has been declared in Essex County, Ontario after two days of torrential rain. (Windsor Star)
A stubborn upper-level low stalled over the Ohio Valley continues to pump deep moisture off the Great Lakes, across southwest Ontario and Michigan. On Thursday, more heavy rain fell across the area, with nearly 160mm in Tecumseh, south of Windsor. Officially, 85mm fell at Windsor Airport, with over 120mm in nearby Detroit. The normal rainfall for the entire month of September is 91mm in Windsor. The rain produced widespread flooding on roadways and in basements. Rivers are on the rise as well, with many exceeding flood stage. A state of emergency has been declared in Essex County, Ontario. More rain is forecast today, with another 50-75mm possible. Across the river in Detroit, the situation was much the same, with major highways closed and water rescues underway. The storm causing the rain will slowly drift southeast before lifting north again this weekend. Cloudy skies and showers are forecast across the Northeast, New England, southern Quebec and Ontario. The heaviest rain will remain south and west of Montreal.

Hurricane Matthew
Matthew strengthened into a hurricane on Thursday, with the center located 535 miles southeast of Kingston, Jamaica Friday morning at 5:00 a.m. Matthew is moving west at 14mph, with 100mph winds. Additional strengthening is expected today, and Matthew could become a major hurricane. The forecast track will take the system west for the next 36 hours before turning north towards Jamaica and Cuba by late Sunday. By the middle portion of next week, Matthew is forecast to be near the Bahamas. The storm may then threaten the east coast of the US and Canada, but it is too soon to determine where and to what extent. Additionally, the possibility does exist that the storm could be swept out to sea, missing the east coast.
