THIS FLOOD WATCH IS NO LONGER ACTIVE.
PLEASE READY THE FLOOD WATCH UPDATE ISSUED ON FEBRUARY 21ST
Message # 2022-02 Issued: 12:30 p.m., Wednesday, February 16, 2022
Subject: FLOOD WATCH issued for all waterbodies and watercourses in the Region
Issued to: Municipalities of Selwyn, Douro-Dummer, Asphodel-Norwood, Otonabee-South Monaghan, Cavan Monaghan, City of Kawartha Lakes, City of Peterborough and Trent Hills, and ORCA’s other partners in flood emergency management.
This FLOOD WATCH is issued to alert municipalities, residents, and businesses that floods are possible.
A low-pressure trough will bring soaring air temperatures reaching 6-7 degrees Celsius. Air temperatures will continue in this range over the next 36 to 48 hours ahead of an arriving cold front. Also, ahead of the cold front is a total of 15 to 25 millimeters of rain. Depending on how the system tracks, there is a possibly that as much as 50 millimeters of rain will fall. As the cold front pushes into the region, there will be strong winds, a drop in air temperatures, and we will receive snowfall of 15 to 20 centimeters. This mix of vastly varying air temperatures, strong winds, differing forms of precipitation will make for messy conditions. Uncertainty in total rainfall amounts translates to a possibility of flooding.
Current conditions include frozen ground covered by a snowpack that is 25-30 centimeters deep with a water content of 85-90 millimeters. Modelling of the warm air temperature/rain event shows 35-40 millimeters of rainfall/snowmelt will be available for run-off, possibly as much as 65 millimeters. However, the snowpack will absorb 5 to 10%, helping to lessen the amount of rainfall/snowmelt to be released into area rivers, streams, creeks, and wetlands. Ice cover break-up is not expected.
Area residents can expect ponding of water in low-lying areas because frozen ground conditions will prevent absorption, followed by the freezing of this water as the air temperatures change back to below zero. Also, ponding will occur around culverts and drainage basin that are not open or are restricted due to snow, ice and/or debris. Residents and businesses along the shores of area waterbodies and watercourses, especially those located in low-lying areas, are strongly encouraged to keep a close watch for possible flooding and to take action to limit or prevent damages due to potential flooding.
