#  This script creates a NIMNAT message, WCL product, and WOU product for training on the 
#  Watch by County procedure. It saves the trainer from having to edit the WCL and WOU
#  products each time the training is done.
#
##############################################################
#
#  The script creates a unique (different time) NIMNAT message and writes it to the local
#  text database.  The script also creates a WCL product with pre-configured counties and
#  a 1 hour expiration time.  The operator and trainee can choose whether to use a different
#  set or the same set of counties for the WOU product.  (Note that the counties are pre-
#  configured in this training script.)  Once a decision is made, the script will write the 
#  WOU product to the locat text database.  
#
#  NOTE:  
#
#  The program does NOT have the WOU product as a practice product.  It is a test product and 
#  the WOU CAN BE SENT OUT TO THE WORLD--SO BE CAREFULL.

#  Edit this section for your CWA.
#
#    Define the following variables:
#
#  WCL_FIPS_COUNTIES:  The FIPS codes for the counties you want to be in the WCL product 
#   Ex.  Montana counties 71 and 105 would be MTC071-105
#       Don't end the variable with a dash.
#
 WCL_FIPS_COUNTIES="MTC071-105"
#
#
# WCL_COUNTY_NAMES:   The names of the counties in the WCL product
#   Ex.  "Phililips     Valley"    These counties would be in the watch
#   Suggestion: Keep it short so all fit on one line or you can use \n for a new line.
#
 WCL_COUNTY_NAMES=" PHILLIPS            VALLEY"
#
# 
# STATE:  The two letter abbreviation of the state where the watch is for.
#  Ex. "MT" for Montana
#
 STATE="MT"
#
#
# STATENAME: The name of the state where the watch is for. 
#  Ex. "MONTANA"   All in caps for product.
#
 STATENAME="MONTANA"
#
#
# WOU_CHANGES_UGC:  FIPS codes for the counties in the watch.  This is for when the list will be 
#                   different from the WCL list.
#   Ex. MTC019-071-105 
#     Added county 19 to the UGC line.  Remember the FIPS codes should be in order. 
#     Note:  No dash at the end of the line and they must be in the same state.
#
 WOU_CHANGES_UGC="MTC019-071-105"
#
#
# WOU_CHANGES_NAMES: County names for the WOU product if different from the WCL product.
#  Ex.  "DANIELS       PHILLIPS    VALLEY" 
#
 WOU_CHANGES_NAMES="DANIELS       PHILLIPS    VALLEY"
#
# 
# HOURS_Z: Hours from Z time.  MDT is 6, MST is 7, EDT is 8. 
#
 HOURS_Z=6
#
#
# TIMEZ: TIME ZONE.  Ex. MDT
#
 TIMEZ="MDT"
#
#
#########
#
# The following variables can be edited.  However, you do not have to.
#
# WFO:  Local WFO code  (Ex. GGW)
#
 WFO=${FXA_LOCAL_SITE}  
#
#
# WATCH_NUMBER:  SPC Watch number.  This will also decide the WOU product that is issued.
#   Note:  This must be a 4 digit number.
