Tropical Hazards
GFE must be running on your workstation.
1. A yellow banner will display on GFE notifying you a TCV has arrived. The yellow banner will instruct you to run the PlotTPCHazards from the Hazards menu.
4. Under the Hazards drop down menu,
click PlotTPCHazards. This will
plot the TPC-issued tropical hazards into the Hazards grid. Click on the
Hazards grid to view the TPC hazards.
Since the PlotTPCHazards operates
directly on the Hazard grid, if other TPC hazards were in effect for part
of the new area, the tool will take care of the needed replacements (i.e.
HU.A becoming a HU.W).
5. Click on the blue disk to Save the Hazards grid. Ensure Hazard is selected and click Save Weather Elements.
Creating a Tropical Watch or Warning for Marine Zones
Each WFO is responsible for issuing tropical
storm and hurricane hazards for marine zones. These marine hazards should
closely match any TPC-issued coastal hazards in both area and threat. If
a cyclone is expected to only affect marine zones, create the hazards as
needed. No TCV is needed.
1.Click on the Hazards grid to display the current hazards on the screen.
2. Click MakeHazard from the Hazard drop down menu.
3. Select Tropical Cyclone from the list of choices. This
will bring up the interface below. Choose the hazard you wish to create.
If a marine zone is not expected to experience cyclone hazard conditions,
but you wish to include them in the HLS, choose HU.S.
4. Left click and drag any marine zone(s) you wish to add. The selected area will become red when added.
5. Adjust the beginning and end times accordingly. The valid time in GHG should cover the expected time of the hazard. Remember that tropical hazards always receive an end time of 000000T0000Z (until further notice) in the HLS and will need to be manually cancelled.
6. Click Run if other hazards need to be created or Run/Dismiss
if this is your final hazard to be created.
7. Repeat process for any other hazard to which you wish to add marine zones. If you are upgrading any hazards, make sure to delete the watch grids before proceeding.
8. In the Hazards drop down menu, click MergeHazards.
9. Click on the blue disk to Save the Hazards grid. Click Save Weather Elements.
10. After creating any needed inland hazards, create and transmit the HLS.
Adding Inland
Tropical Hazards
1. Click on the Hazards grid to display the current hazards on the screen.
2. Click MakeHazard from the Hazard drop down menu.
3. Select Inland Tropical Cyclone from the categories of hazards and choose the type of inland hazard you wish to create. If a land zone is not expected to experience cyclone hazard conditions, but you wish to include them in the HLS, choose HU.S.
4. Using the slider bars on the right, choose the timeframe you are forecasting the conditions to occur.
5.Left click and drag any inland zone(s) you wish to add. They will become red when added.
6. Click Run if other inland hazards
need to be created or Run/Dismiss if this is your final hazard to be created.
7. Repeat process for any other inland hazard you wish to create. If you are upgrading any hazards, make sure to delete the watch grids before proceeding.
8. In the Hazards drop down menu, click MergeHazards.
9. Click on the blue disk to Save the Hazards grid. Click Save Weather Elements.
10. After creating any needed mairne hazards, create
and transmit the HLS.
Upgrading the Tropical Hazards
3. If the warning will be similar in area and time, click on the hazard you wish to upgrade, then select MakeHazard. Then proceed to Step 6. .
4. If the warning is quite different in area and time than the watch, right click over the watch, drag down to Delete Grid and release mouse button.
5. Follow either Adding Marine Zones to a Tropical Watch or Warning or Adding Inland Hazards to the Grid to create the new, upgraded hazard(s).
3. Click on the tropical hazard grid you wish to edit, then click MakeHazard from the Hazard drop down menu.
4. Left click once on each red inland or marine zone you wish to remove. They will change to the default black background of the tool. If these zones are desired in future HLS issuances, add the HU.S hazard to them. See either Adding Marine Zones to a Tropical Watch or Warning or Adding Inland Hazards to the Grid.
5. Click Run or Run/Dismiss at the bottom of the tool.
6. Repeat process for any other tropical hazard from which you wish to clear an area.
7. In the Hazards drop down menu, click MergeHazards.
8. Click on the blue disk to Save the Hazards grid. Click Save Weather Elements.
9. Create and transmit the HLS.
Cancelling/Ending Tropical Hazards
1. Click on the Hazards grid to display the current hazards on the screen.
2. In the Hazards drop down menu, click SeparateHazards. A temporary hazard grid will be created for each hazard in effect.
3. Click on the watch you wish to cancel, then right click and hold for menu.
4. Drag down to Delete Grid and release mouse button.
5. Repeat process for any other hazard you wish to end.
6. In the Hazards drop down menu, click MergeHazards.
7. Click on the blue disk to Save the Hazards grid. Click Save Weather Elements.
8. Create and transmit the HLS.
The only product needed for the tropical hazards is the HLS. The NPW will not be used for tropical hazards and the CWF will only contain the tropical headlines, not the VTEC.
1. If hazards are currently separated into temporary hazard grids, finish your edits then click MergeHazards from the Hazards drop down menu.
2. Click on the blue disk to Save the Hazards grid. Click Save Weather Elements.
3. On the Products drop down menu, click Publish to Official. Make sure to publish all times!
4. Under the Products drop down menu, click Formatter Launcher.
5. In the Formatter Launcher window, click Products, then choose Hazard --> Hazard_HLS (Baseline) or Hazard_HLS (ER HLS).
6. Click on the silver gear button to start the chosen formatter.
7. If using the baseline formatter, select your storm type
and enter the storm name. If using the ER HLS, select your NHC package family.

8. If previous text is desired, select use previous HLS.
9. If desired, select each VTEC type and delete and/or reorder the subheadlines.
10. Click OK to run the HLS.
11. Edit every segment, making sure NOT to change the subheadline names. You can delete any subheadlines you do not wish to include in the final HLS.
12. QC the product, and run the spell checker. The TR and
HU hazards will have a hazard end time of 000000T0000Z for UFN. This is
correct.
13. When you are ready, click Transmit to send the product.
Click Transmit again on the transmit window which comes up to actually issue
the product.
14. Check the GHG Hazards Monitor to ensure your hazards
are there which verifies the transmit was successful.
