Watershed Condition Statement: Flood Outlook


Flood Potential: Moderate
Ice Jam Potential: High

Issued to: local municipalities and school boards, local conservation authorities, emergency response agencies, health unit, media, NVCA board and staff

Date: February 19, 2018 (10:00AM)

Weather Conditions

The Nottawasaga Valley Conservation Authority advises that temperatures are forecast to reach 12 degrees Celsius on Tuesday, with daily highs expected to remain near or above freezing for the rest of the week. Rainfall amounts of approximately 25mm are forecast for both Family Day Monday and Tuesday, with an additional 5 mm on Wednesday. Warmer than normal temperatures late last week has caused snowpack to begin to melt.

Issues

The forecast warmer temperatures will continue the melting of snowpack resulting in an increase in water levels throughout the watershed. The forecast significant rainfall over three days will also contribute to increase in water levels. Stream banks can be slippery and unstable, which combined with extremely cold water temperatures can create hazardous conditions around our rivers and streams. There is also the potential for ice jams and localized flooding. No major flooding is anticipated at this time.

Actions

Hazardous conditions 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 Outlook Statement will be in effect until 4:00 p.m., Friday, March 2, 2018.
