Water safety bulletin issued, significant rainfall expected

(SCRCA)

St. Clair Region Conservation Authority officials issued a water safety bulletin on Friday, October 25 as 30 to 50 mm of precipitation is forecasted over the next 48 hours.

Environment Canada officials have also issued a special weather statement and a frost advisory across Chatham-Kent.

Officials say water levels are expected to rise

“The precipitation forecast for the weekend calls for total accumulations between 30 mm and 50 mm,” SCRCA officials said in a media release.

“Water levels are anticipated to rise with the potential for localized flooding in floodplain areas, parks and farm fields throughout the region. Soils are expected to be saturated from the rain and could contribute to ponding, increased runoff into watercourses, and possible increased erosion and seepage issues.”

SCRCA officials added: “High amounts of rainfall in a short period of time can lead to increased runoff and flash flooding, particularly in urban areas. River banks are expected to be slippery, with possible minor erosion. Residents are reminded to avoid watercourses and flooded areas due to slippery banks and cold, swift moving water. Children and pets should be kept away from the water.”

The Conservation Authority continues to monitor watershed conditions and will issue advisories to municipalities and media should flood
issues arise.

Municipal emergency response staff and road superintendents should monitor local conditions closely.

This message from the SCRCA will remain in effect until Monday, October 28, 2019 unless otherwise updated.

Environment Canada says a significant rainfall is possible Saturday night into Sunday morning.

“A low pressure system will approach Southern Ontario late Saturday with rain developing over the area Saturday afternoon. Rain, heavy at times, will continue through Saturday night into Sunday morning,” forecasters say.

“Total rainfall amounts of 30 to 50 mm are possible, with the heaviest rain falling overnight Saturday. Gusty easterly to southeasterly winds up to 60 km/h are possible. Rain will taper to scattered showers near midday Sunday.”

Rainfall warnings are not expected to be issued for this event, Environment Canada officials say.

“Ensure that storm drains are clear of leaves and other debris. Heavy downpours can cause flash floods as well as water pooling on roads. Local power outages are possible,” forecasters say.

Forecasters have also issued a frost advisory across Chatham-Kent.

“Frost may damage some crops in frost-prone areas. Temperatures are expected to drop to the freezing mark or below tonight. Take preventative measures to protect frost-sensitive plants and trees,” forecasters say.
