How should our office tone alert tropical hazards on NWR?
• How can I know what zones to expect from the NHC breakpoints? • NWSHQ and NHC worked with the regions/WFOs to come up with a list of zones that will be generated with the various breakpoint segments. That file can be found here. Look for your office and read the instructions at the top on how to determine which zones will be included when there are multiple tropical hazards involved. • How can I prevent bad VTEC and/or UGCs? • Follow the training! The NWS learning center course outlines the correct way to create and edit the various hazard grids and the subsequent HLS. Many offices run through the pertinent sections prior to a landfalling cyclone. The tropical jobsheets can also be utilized during operations. • NEVER preselect an NHC hazard grid before going into MakeHazard. It can cause zones to be dropped from active hazards. OB8.3.1 will not allow this to happen. OB8.3.1 begins deployment in late September. • Use MakeHazard to edit tropical grids. Do not try to add or delete areas
