I just found out something that I thought might interest others.
If you’ve opened a Weather Watcher Severe Alert window and later open a Weather Watcher Forecast window you can revisit the alert by RIGHT clicking in the middle of the Forecast window and clicking on the Back option. It is not necessary to go to the Current Forecast window to revisit the alert.
The middle area of the forecast windows works best for this because locations closer to the edges bring up the Weather Watcher options menu rather than the IE options menu.
