A series of Alberta Clipper type low pressure systems will sweep through the province in the next five days bringing in slightly warmer weather for Southern Ontario. Daytime temperature will be around 0 to 5 degrees centigrade intermittently in the next 5 days for the south. For the northeast daytime temperatures will remain sub-zero for the next few days with slight warming on Monday pushing it slightly above zero degrees. Night time temperature will be sub-zero for much of the province in the next five days. There is minimal forecast snow and/ or rain in the range of 5 to 10 mm/cm for southern Ontario due to these systems.
Stream flow conditions in the province are mostly within the seasonal range. Most lakes and streams are frozen at this time of the year. Snow cover in the south ranges from 20 cm to 80 centimetres. Forecast warm weather in the next few days could result in some snow melt and localised flooding mainly due to drainage issues or ice jams. No major flooding issues are expected. A close watch on local conditions is recommended.
This message will be in effect until March 10th, 2014 5:00pm.
What are Provincial and Local Flood Messages?
In Ontario, there are two main types of flood messages: local messages and provincial messages. Local messages are issued by conservation authorities, or by MNR districts in areas that are not serviced by conservation authorities. Provincial messages are broader, high-level messages issued by MNR's Surface Water Monitoring Centre to local agencies and partner ministries to alert them to potential flooding.
Your local conservation authority is responsible for local flood messaging and your local municipality is responsible for on the ground flood response. For more information on your local situation, check with your conservation authority or municipality. If you live in a community that is not serviced by a conservation authority, any flood watches or flood warnings in your area are issued by the nearest MNR district office. See Who to Contact for Flood Information.
Types of Provincial Flood Messages
- The Provincial Flood Watch provides consistent and timely technical information regarding flood potential to those agencies that must respond to or deal with flood emergencies. The message prepares the provincial emergency response system for flood conditions that may develop somewhere in the province.
- The Provincial Watershed Conditions Statement provides information on provincial watershed conditions relative to the flood potential. The report also provides an outlook of expected spring flood conditions.
Types of Local Flood Messages
- Flood Warning indicates flooding is imminent or occurring within specific watercourses and municipalities.
- Flood Watch indicates the potential for flooding exists within specific watercourses and municipalities.
- Watershed Conditions Statement indicates a potential for flooding or other conditions that pose a risk to personal safety, such as high flows, unsafe ice, and high lake levels. There are two types of statements:
- Water Safety indicates that high flows, melting ice or other factors could be dangerous for such users as boaters, anglers and swimmers but flooding is not expected.
- Flood Outlook gives early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high winds or other conditions.
