Occasionally, only a subset of zones under a hazard will
need to be extended while the rest will be allowed to expire. The following
steps are the correct way to accomplish this. Using other means will cause dissemination
issues with the product due to confusing VTEC.
The graphic below shows the existing hazard that is about to expire.
Open the MakeHazard tool by clicking Hazards
--> MakeHazard from the GFE menu bar. Do NOT pre-select
(i.e. prime with) the existing hazard as that will cause a change
in the expiring zones, which is not desired.
Select the desired hazard subgroup (i.e. Marine),
hazard, zone(s) and times. Always start at the current time and
have it end in the number of hours you wish to extend the hazard.
Run MergeHazards by clicking Hazards --> MergeHazards from the
GFE menu bar. You will have at least 2 hazard grids, the original hazard and
a new grid with just the zone(s) being extended.
Save and Publish the entire hazard grid.
Run the appropriate formatter by clicking Products --> Formatter Launcher
from the GFE menu bar then selecting your formatter (i.e. CWF) and clicking
the silver gear button.
Make the necessary changes to the text of your product. Note you will have
one segment for EXP and another for the EXT.
Run the spell check by clicking Edit --> Spell Check from the product
