SDG COUNTIES, Ontario - Residents of SDG Counties are urged to prepare now for a potentially-significant winter storm and an increased risk of flooding in the coming days.
Forecasts for this kind of storm are notoriously finicky, and while there is always the potential for systems to change direction or evolve in unexpected ways, it is always prudent to be prepared.
Environment Canada warns that our region may experience a prolonged period of freezing rain -possibly up to 24 hours - with ice accretion reaching 10–20 mm. This system begins late tonight or early Wednesday and may persist through Wednesday night. Freezing rain may fall heavily at times, and in some areas the precipitation may not freeze immediately, increasing the potential for localized flooding in low‑lying locations due to pooling water. Prolonged utility outages and significant damage to trees, structures, and power infrastructure are considered likely.
Local conservation authorities are also advising of enhanced flood risks as temperatures rise and rain intensifies. The Raisin Region Conservation Authority notes that warmer weather and incoming rainfall may cause high water levels, slippery banks, and flooding in low‑lying areas, emphasizing the need for early precautions such as securing loose outdoor items and ensuring sump pumps and backup generators are ready. Likewise, South Nation Conservation reports that ground conditions are saturated and rivers remain high; additional rainfall could cause ice movement, ice jams, and renewed flooding of floodplains and poor‑drainage areas. Residents in historically flood‑prone zones should take immediate steps to protect their property.
How you can prepare
Plan for power outages
With heavy ice expected, long‑duration power failures are possible. Stock up on enough heating fuel, firewood, propane, or backup power sources to last several days. Ensure generators are fueled, maintained, and operated safely outdoors.
Build an emergency supply kit
Prepare for at least 72 hours of self‑sufficiency. Include:
Non‑perishable food and bottled water
Flashlights, batteries, and candles
Medications and first‑aid supplies
Charging devices and battery packs
Warm blankets and clothing
Protect your home from flooding
Confirm your sump pump is working and equipped with a backwater valve.
Keep a portable backup generator and pump accessible.
Clear downspouts and ensure water drains at least 3 m from your home.
Make sure driveway culverts are free of debris.
Move valuables and equipment from basements or ground‑level areas.
Stay safe outdoors
Avoid walking or driving on icy surfaces. Steer clear of rivers, streams, or any water bodies - banks are unstable and ice is unsafe. Do not approach downed power lines.
