If the above button doesn't work... with your RIGHT mouse button, click [HERE] and select "Refresh" or "Reload Frame" from the menu that pops up. This radar now has Stormtracking. When there are strong storms in the area, our computer will plot red arrows showing the direction of the storms. The white dot shows the location of the storm at the time in the blue box. The tip of the arrow is where the storm will likely be 30 minutes later.
