IW StormRisk storm track arrows and colour key

/

The StormRisk storm track arrows have been added so that you can see the predicted direction of travel of the storm(s).

With the radar turned on:

Here are some examples of the colours of the outlines with the Total Severe Risk percentages. Note that the thickness of the outline also increases when the risk increases as well. You can see that in some of the examples where there is another outline present in the screenshots (24-48).

Note that the black colour for greater than 85% is a bug. You will not be able to see against the black map but it will show up well when radar is on.

IW StormRisk is live

/

IW StormRisk is live for all IW Pro users and combined alert polygons are live in Canada as well!

To turn on IW StormRisk just click on the menu (three bars at the top left) and click to turn it on:

IW StormRisk only works as far north as 51N (basically just south of Calgary) but we have plans to extend it further north to 55N, which will include locations like Saskatoon and Edmonton.

The thickness of the outline is related to the risk level as well as the colour of the outline is related to the type of risks. Here are some examples:

Look for irregular shapes and click on them to see the IW StormRisk:

Mosaic Radar Layer

Measurement tool in single mode

/

There is now a measurement tool that you can uses when you are in single mode.

  1. Choose Single Mode with any of the products.

  2. Click on the small open circle on the right side of the screen.

  3. With your mouse (PC) or finger (mobile) choose the center point from which to measure and hold until you reach the point you wish to measure the distance to.

  4. The radius of the circle (distance) will be displayed on the screen.

  5. You can also use this circle to “mark” a location and then zoom out.

  6. Click on the small circle again to remove the measurement circle.

In the above example Sussex was chosen as the center mark and I picked a random distance so that when I zoomed out I could see the location of Sussex.
