# Submitted by: JHWRF_PRE_MASTER
# Submits:
#   JHWRF_PREP_HYBRID for hours 0-12 (FIRST_PREP=0, LAST_PREP=2)
#   JHWRF_OCEAN_INIT, but only if MODEL=COUPLED if $stormlabel.holdvars.txt
#   JHWRF_WPS

# Primary scripts and parameter files:

#   scripts/exhwrf_pre_atmos.sms -- passes control to hwrf_pre_atmos.sh
#   ush/hwrf_pre_atmos.sh -- calls hwrf_link_input.sh to make symbolic
#      links to the GFS or GDAS data, as needed.  Also gets ALL of the
#      tcvitals entries for the current storm from the tcvitals file.
#   ush/hwrf_get_oper_loop.sh -- copies look current data to local areas
#   ush/hwrf_subset_gribs.sh -- subsets the GFS hour 0 grib file

# Primary executables:
#    wgrib
