NORTH STORMONT, Ontario - The Raisin Region Conservation Authority (RRCA) is issuing a Flood Outlook Statement for the RRCA jurisdiction.
Beginning mid-day on Wednesday March 22, air temperatures are forecast to climb above zero and may remain above zero continuously for two to three days. On Thursday March 23 temperatures are expected to peak above 5°C and 10-20 mm of rainfall is forecast.
The forecasted combination of rainfall and snowmelt is expected to rapidly increase water levels and flows in local watercourses beginning on Thursday, March 23. Flooding of low-lying areas normally water-covered in spring is possible: Watercourses are currently expected to reach their highest levels of February and March so far this year (however, water levels are not expected to exceed those of early January). The RRCA encourages residents to take extra caution near water bodies and secure items that may float away as water flows increase.
Under the current weather forecast, water levels are expected to peak on March 24-25. Water levels are then expected to begin an overall decline through the following days.
This statement is in effect until Monday, March 27, 2023, at 4 p.m. The RRCA will continue monitoring water levels and weather forecasts as part of the Flood Forecasting and Warning program. Updates will be provided as conditions change.
