The Nottawasaga Valley Conservation Authority advises that the Flood Outlook Statement issued February 19, 2018 is now upgraded to a Flood Watch.
Approximately 20-30mm of rain has already fallen across the watershed, with an additional 15-20mm forecast through Wednesday morning. Temperatures are forecast to reach 13C on Tuesday. Environment Canada has issued a rainfall warning stating that total rainfall amounts from Monday through Wednesday may be in the 50 to 75mm range.
Water levels are currently rising as a result of recent rainfall and snowmelt. The forecast additional rainfall on frozen or saturated ground will further increase water levels in area streams. Where river ice is still present, there is the potential for ice jams. Water could overflow banks and cause flooding in some areas. Widespread flooding is not anticipated at this time.
Municipalities, emergency services and individual landowners in flood-prone areas should be on alert.
Hazardous conditions may exist around all waterbodies, as there is a high risk of life-threatening injury if a person falls into the extremely cold water. The public and especially children are advised to stay away from all waterbodies.
The Nottawasaga Valley Conservation Authority continues to monitor river and stream conditions and will issue additional messages as conditions warrant. This Flood Watch Statement will be in effect until 4:30 p.m., Friday, February 23, 2018.
