🛠️ Requested Features (Updated May 2025)

/

We appreciate all the suggestions that have come in from our awesome community! Some of these features are already in development or under consideration, while others may take time depending on feasibility and system performance. If you have more ideas, feel free to reach out as your feedback helps shape IW Pro.

✅ Already Requested (From Aug 10, 2023)

  • Lighter coloured map option
    A more contrast-friendly map theme for better visibility during daylight or in low-contrast setups.

  • Drop-down boxes for radar products and elevation/tilts
    In addition to arrows, having a drop-down menu can help quickly select specific options.

  • Switch settings to on/off toggles instead of dropdowns
    Aimed at improving mobile usability, especially on touch-based browsers with limited UI support.

  • Include timestamp info in alerts
    More detail about when each alert was issued or last updated.

  • Auto-load new frames during radar animation
    Improve Live Mode so new frames are seamlessly added during playback.

  • Different error messages when a radar station is down
    Distinguish between “station offline” and “network/load issue” to help users troubleshoot faster.

📝 New Suggestions (2024–2025)

  • Lightning and alerts in Historical Mode
    Currently, historical radar does not display lightning or alerts. This is a frequently requested feature.

  • Improve Great Lakes visibility
    Some users have noted the lakes are hard to see (black on almost black). A visual update is under consideration to make them stand out more clearly.

  • Improve accuracy of storm track arrows
    Arrows occasionally point in the wrong direction. Watching a few frames of reflectivity can help, but backend refinements are planned.

  • Precipitation type (snow/rain/etc.) in station radar
    Currently shown only in Mosaic Radar; users would like to see this per station if feasible.

  • Map and radar layer customization
    This is on the roadmap! Many users have asked to customize map backgrounds, radar colours, and toggle overlay layers.

⚠️ Features Temporarily Unavailable

  • U.S. Alert Descriptions
    These were lost during a rollback to a previous version and are currently not displaying. We plan to restore them in a future update.

  • Environment Canada Thunderstorm Forecasts
    This feature is temporarily unavailable but will return in a future version.

Included in this video is what can be seen on radar.

Tip for map on mobile devices

/

On some mobile devices if you select Desktop site in Chrome you will see more of the map. Click the three dots to select Desktop site.

Teressa M reported that is works well with a Samsung S20.

White screen on mobile - Update Aug 15

/

Update Aug 15:

A possible solution to a white screen on a mobile device is to clear the browsing data on chrome. Specifically the Cookies and Site Data. You may see a spinning circle or a plain white screen.



Update Aug 9: The white screen when logging in should no longer be an issue. You should get the password box in portrait now.

If you are only seeing a white screen when you click on the link for IW Pro please turn your device sideways (landscape mode) and then the password box will pop up. You can turn it back to portrait mode after entering your password.

Hail spike example

/

You need to turn off Canadian Noise Radar Reduction to see it and don't forget to reload the page when you make a change to a setting. When hail is really large you can get a spike. "A hail spike or three body scatter spike (TBSS) is an artifact on a weather radar display indicative of large hail. They are identified by a spike of weak reflectivity echoes that extend out from a thunderstorm, and away from the radar site." https://en.wikipedia.org/wiki/Hail_spike

How to read radar

/

There are some great YouTube videos that describe how radar works and how to read radar. While they use different apps the principles are the same.

We will add some of our own videos later as our app has some unique features that other apps do not have.

Live Mode vs Regular Mode vs Historical Mode

/

When you are in Live Mode IW Pro will auto load new frames when they are available. If you don’t have Live Mode on (you can turn it on in settings) then you will see the last frame that you loaded.

Note that if you are playing a series of frames it will not automatically add a new frame unless you reload.

If you wish to see past radar data you can click on the UPDATED AT Time to change the date and time.

Here is the Didsbury, AB EF4 tornado in historical mode:

Canadian Alerts

/

IW Pro has the fastest alert polygons & radar loading in Canada.

To turn this feature on/off go to settings (the three bars in the upper left hand corner).

You can also control which alerts are displayed including IW Instant Updates.
