|
|
</span><small>This simple scenario describes using MakeHazard to create
|
|
one hazard. It assumes you<br>
|
|
are starting with no hazards in your Hazard grid.<br>
|
|
<br>
|
|
1. Start MakeHazard:<br>
|
|
<br>
|
|
<img style="width: 800px; height: 497px;" alt="Make Hazards Tool"
|
|
src="images/MakeHazards.png"><br>
|
|
<br>
|
|
2. Select the Hazard you wish to create under the Hazard List.<br>
|
|
<br>
|
|
<img style="width: 800px; height: 497px;" alt="Make Hazards 2"
|
|
src="images/MakeHazards2.png"><br>
|
|
<br>
|
|
3. Select the start and end time for the hazard you are creating.<br>
|
|
<br>
|
|
<img style="width: 800px; height: 497px;" alt="Make Hazards 3"
|
|
src="images/MakeHazards3.png"><br>
|
|
<br>
|
|
4. Select the zones for this hazard. Note: If you do not select zones
|
|
at this step, the hazard type and time range will<br>
|
|
be applied to the current active edit area in GFE.<br>
|
|
<br>
|
|
<img style="width: 800px; height: 497px;" alt="Make Hazard 4"
|
|
src="images/MakeHazards4.png"><br>
|
|
<br>
|
|
5. Press Run/Dismiss. The tool will close, and a temporary hazard grid
|
|
will be created. Notice in the example<br>
|
|
below, the grid name in hazISW, the temporary grid for an Ice Storm
|
|
Warning.<br>
|
|
<br>
|
|
<img style="width: 800px; height: 497px;" alt="Make Hazards Temp Grid"
|
|
src="images/MakeHazardTempGrid.png"><br>
|
|
</small><span style="font-weight: bold;"></span></big><br>
|
|
6. The final step to creating a simple hazard is to run the <a
|
|
href="MergeHazards.html">MergeHazards</a> tool, which will recombine
|
|
all <br>
|
|
temporary grids back into the actual hazard grid.<br>
|
|
<br>
|
|
<img style="width: 800px; height: 497px;" alt="Finished Hazard grid"
|
|
src="images/MakeHazardHazGrid.png"><br>
|
|
<br>
|
|
At this point, you can run the formatter launcher, and create your
|
|
hazard products. <br>

<li>Run <a href="SeparateHazards.html">SeparateHazards</a> to break

|
|
<li>Click on the temporary hazard grid.</li>
|
|
<li>Run <a href="MakeHazard.html">MakeHazard</a> and adjust the
|
|
times or areas of the grid.</li>
|
|
<li>If you wish to remove the hazard completely, simply delete the
|
|
temporary grid.</li>
|
|
<li>Run <a href="MergeHazards.html">MergeHazards</a> to recombine
|
|
the temporary grids.</li>
|
|
<li>Save, Publish, and run Formatter launcher for the hazard.<br>
|
|
</li>
|
|
</ul>
|
|
<big>
|
|
The Hazards grid will be locked when you run the SeparateHazards
|
|
procedure to prevent conflicts from other users. <br>

instance, if you have a Winter Storm Warning (WS.W) from 12Z to 22Z,

but you need to talk<br>

about snow in the west and freezing rain in the east, you might want to
|
|
break this into two <br>

segments. Here is an example using MakeHazard:</small></span></small></span><span

<br>

<span style="color: rgb(0, 0, 0);">Step 1: Run MakeHazard for the first

segment. Enter 1 in the ETN/Segment Number box. Press Run.<br>

|

|
|
<br>
|
|
Step 4: Save and publish your hazard grid. Although it looks like one
|
|
area, note the difference in the legend. <span
|
|
style="font-style: italic;">Note that you can switch the Hazards
|
|
display to a combination of Image and Bounded Area, and then increase
|
|
the Line Width in order to see the different segments.</span><br>

|

|
|
<br>
|
|
Step 5: Run the product. Notice that although VTEC codes are the same
|
|
and headlines are the same,<br>
|
|
that the product has been forced into two segments.<br>
