Cochrane, Dryden, Fort Frances, Hearst, Kenora, Nipigon, Red Lake, Sioux Lookout, Thunder Bay, Timmins
MNR Southern Region
As of July 21st, 2014 water levels and flows for most of the region are at or near seasonal values. Forecast precipitation over the next five days is 0-20mm.
MNR Northeastern Region
As of July 21st, 2014 water levels and flows are elevated for portions in the North Bay - lower Northeastern region. Forecast precipitation over the next five days is 50-80mm.
MNR Northwestern Region
As of July 21st, water levels and flows for portions of Dryden, Kenora and Fort Frances districts remain quite elevated due to recent precipitation. Total forecast precipitation for the region is 50-100mm for the next five days.
A frontal system moving across the northern Ontario will bring sweltering temperatures, high humidity and significant rainfall to Kenora, Dryden, Thunder Bay, Nipigon, Hearst and Cochrane Districts over the next 2 days, especially in the area of an embedded deep low pressure area that will travel along the frontal wave over the next 24 – 36 hours.
From Lake of the Woods and the international border and Rainy River, to Atikokan and Upsala, heavy rainfall with amounts 30 – 50 mm can be expected starting near midnight tonight, along with severe thunderstorms that could contribute an additional 25 – 50 mm before morning.
The deep low pressure zone will move eastward along the frontal through the day tomorrow, giving similar quantities of rainfall to the Thunder Bay and Nipigon regions. General rainfall 30 – 50 mm is expected to occur along the frontal wave that will extend through Geraldton, Hearst, Kapuskasing, and Cochrane, while the low pressure system will move relatively quickly along the frontal zone, and exit eastward into Quebec overnight on Tuesday or early Wednesday morning.
Water levels and stream flows across a wide portion of Dryden, Kenora and Fort Frances districts remain elevated due to recent precipitation. Forecast precipitation, especially should thunderstorms develop is likely to result in the continuation, and in some areas, the increase of flooding in area lakes and rivers that are already in flood conditions.
Elsewhere through the Northwest and Northeast that will be affected by this system, the expected heavy rainfall with the added severe thunderstorms where they develop can overwhelm local drainage systems, and localized flooding can be expected.
A close watch on local forecasts and conditions is recommended. The message will be updated based on the changing weather/streamflow conditions.
This message will be in effect until (or updated before) July 23, 12:00pm
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. 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.
