Windsor-Essex got soaked on Friday, and the Essex Regional Conservation Authority (ERCA) has issued a flood watch for the entire region, and a warning for one community.
A slow-moving system brought soaking rain to the area, with at least 30 millimetres falling by early Friday afternoon.
Lakeshore appeared to have received the most rainfall, and ERCA issued a flood warning for the Municipality.
"Forecasts suggest that this storm can continue through the day and produce total amounts of rain up to 100 millimetres in some areas," read the flood watch. "The most affected areas will be the tributaries that flow northerly through Windsor, Tecumseh, and Lakeshore. However, this is variable and depends on the areas that may receive higher volumes of rain."
ERCA Watershed Management Services Director James Bryant said smaller drains and creeks are expected to fill, and larger watercourses may rise to spill into low-lying areas.
Residents are urged to exercise caution and stay clear of areas where flooding may likely happen.
The flood watch and warning are in effect until noon on Saturday.
