Environment Canada Map: Radar and Wind Turbine interference

Environment Canada
The radar site locations are marked with a black dot. A green circle shows a 50 kilometre radius around the radar.  Inside this 50 kilometre ring, potential interference with the radar may exist and direct consultation is strongly suggested. Major roads and cities are indicated in dark blue.

The colour display surrounding the radar(s) represents whether wind turbine blades could be seen by the respective radar (in yellow) and if the wind turbine towers can be seen (in red). The visibility maps have been created for turbine models with turbine tower heights of 100 meters and blade lengths of 50 meters (for a total blade height of 150 meters). If any part of a turbine is visible to a weather radar, interference is expected, but if the turbine tower is visible (in red) more severe impacts may occur. Any region not covered by the colour display indicates that a wind turbine with a total height of 150 meters should not be visible to the radar. However, a turbine with a blade height greater than 150 meters may be seen and further analysis is necessary. View Map

  1. Environment Canada can accommodate wind developers because the Ontario IWT sites are also covered by official U.S. Doppler Radar sites? And this even includes Ottawa.

    http://radar.weather.gov

    Click on any of the blue dots for radar coverage of the areas. Page bottom box for “Mosiac Sections” for how much of Ontario is covered by U.S. Doppler Radar for complete picture.

    Rural Ontarians can use information on the whole picture/situation and not just part of it. Lake Huron is covered by radar stations in Detroit and Central Northern Michigan which also includes part of Ontario.

  2. During the weather event last night, the lights in the house kept dimming for a second and then back to normal. Happened dozens of times.
    I didn’t dare to turn on any electronics.

    • I also disconnect when that happens but the storm passed north of here so could view both radar sites.

      U.S. Doppler radar also has green boxes to show where flooding is expected but not shown for Canada.

      None of the U.S. warning boxes are shown on radar images that cover Canada. For Canada weather warnings/alerts are done by Environment Canada.
