Tip #1:  For a hazard event, if any zone in the hazard will remain in effect for the same Hazard Type, do not end the hazard. Instead, select the hazard event in the Console, right-click on the zones to be removed, then select by Maps to create a new hazard event for these zones.

Tip #2: To help make the GFE and Hazard Services hazards easier to distinguish when overlaid, change the Alpha channel of the GFE Hazards grid.
