Weather Alerts in IW Pro: More Control Than Ever

/

IW Pro now includes a powerful set of Weather Alert controls, giving you more flexibility over what you see and how you see it.

Control official weather alerts and how they appear on the map

IW Pro displays official weather alerts from Environment Canada and the U.S. National Weather Service, and now you can fully customize how those alerts appear.

Customize the Alerts You Receive

You can now choose exactly which alerts matter to you.

Under Weather Alerts, you’ll find:

  • Canada Alerts and U.S. Alerts toggles

  • Full control over alert categories, including:

    • Tornado & Severe Storms

    • Winter Weather

    • Flooding

    • Tropical & Hurricane

    • Marine & Coastal

    • Heat & Fire

    • Wind & Air Quality

    • Geological Hazards

    • Public Safety

Choose which types of official alerts you want to see

Each category can be expanded so you can turn individual alerts on or off (for example, Blizzard Warnings, Snow Squall Warnings, or Severe Thunderstorm Watches).

Customize individual alert types within each category

This allows you to reduce noise and focus only on the alerts that matter most to you.

Turn Alerts On or Off Anytime

At the top of the section, you’ll see a simple Enable Alerts toggle.

  • Turn it on to display official alerts on the map

  • Turn it off to hide them completely

Control How Alerts Look on the Map

You can also adjust how alerts appear visually:

  • Alert Outline + Fill (on/off)

  • Outline Thickness

  • Drop Shadow

  • Transparency

Adjust how alerts appear with outlines, shadows, and transparency

This helps you balance visibility without overwhelming the radar view.

Instant Updates (IW Pro)

In addition to official alerts, IW Pro includes Instant Updates.

These are not official weather alerts. They are issued by the Instant Weather team to provide additional real-time insights, such as:

  • Rotation detected

  • Developing storm features

  • Other notable conditions

You can turn Instant Updates on or off separately, depending on how much additional information you want to see.

nstant Updates are separate from official alerts and provide additional real-time insights from the Instant Weather team

Why This Matters

Previously, it was not always clear:

  • Which alerts were being shown

  • Why certain alerts appeared

  • Or how to filter them

Now, you are in full control of both:

  • Official alerts from trusted sources, and

  • Additional insights from the Instant Weather team

If you have any feedback on the new alert settings, let us know. We are continuing to improve IW Pro based on your input.
