Here is today's summary of NHC computer operations:

----------

TAFB:
1. Update on errors when pulling up the Objective Aids panel in the TAFB  
version of ATCF on the crappie workstation. A team of TSB developers was  
unable to replicate this problem, which is known to be intermittent. The  
only viable explanation could be that this occurred when the (large) ATCF  
decks were being rsync'ed (copied) from atcfsvr1 to atcfsvr2, which happens  
every 20 minutes via cron. If this problem becomes more pervasive, then TSB  
will reinvestigate.

2. Forecasters are reminded not to launch N-MAP and ATCF concurrently on  
the same N-AWIPS workstation. This causes NMAP to crash when a user  
attempts to use the distance-measuring tool (blue icon) in NMAP, requiring  
a reboot of the N-AWIPS workstation.

3. The GFE seems to be running slow at both the Atlantic and Surface  
Analysis desks. TSB AWIPS SysAdmin Chris Mello will investigate.

4. No preTCM files are available for systems that are forecast by CPC  
[CPHC?]. This should be an item to address for next hurricane season.

Explanation from TSB's Matt Sardi:

NHC transitioned a copy of our preTCM generation script  
${ATCFSCRIPTS}/create_pretcm_rcl.pl to CPHC so they could produce preTCMs  
locally on their ATCF server.

The problem is downstream: NHC sends our preTCM to our AWIPS and the  
product is pushed out to a list of WFOs. Since CPHC has just one WFO, HFO  
in Honolulu, pushing to the HFO AWIPS is all they need locally.

Unfortunately, since the preTCM/RCL is only saved on HFO's system, TAFB  
won't have access. For TAFB to see CPHC generated preTCM/RCLs, TSB  
developers will need to work with Honolulu to set up the triggers and a  
send script on their system. Since we don't have access to their AWIPS,  
Matt will need to work with their technical people in Honolulu with AWIPS  
knowledge. This will require inter-office coordination [across 6 timezones].
HSU:
1. There is an N-MAP application that NHC uses that creates VTEC code for  
tropical storm and hurricane watches and warnings. There is a bug in this  
code that is improperly coding the message. Specifically, the code has  
trouble with properly cancelling a TS Warning when changing from a TS  
Warning and Hurricane Watch to a Hurricane Warning for the same area. A fix  
for this problem is needed as soon as possible. TSB Chief Mark DeMaria has  
submitted an NCO Help Desk ticket with Priority Level: 1 - Immediate  
(ASAP/1 hour) on this issue.

2. A Pre-TCV and a National TCV were issued on TS Hermine. However,  
Hurricane Specialists had problems with the finalized hazards grids for  
Hermine for the 21Z advisory. TSB will followup with HSU to streamline the  
process.

3. The initial version of the 03Z storm surge watch/warning graphic was  
corrupted. TSB developer Matt-of-all-trades Sardi was able to quickly  
remove it from NHC's web site, allowing SSU to re-create and repost the W/W  
graphic successfully.
Other items:
 From the SDM's log:

1. Assessment of GOES-13 (GOES-E) satellite image data quality for model  
input.

NESDIS' Jason Taylor stated that Star Tracker 3 [navigation system]
is still an issue. NESDIS is requesting that any customer input
regarding the quality of the products be communicated to NESDIS.
This will assist NESDIS is deciding whether to initialize Star
Tracker 2. Initializing Star Tracker 2 would not have the same
thermal characteristics, so the products would be different.
Therefore, this is not the preferred solution for NESDIS. NCO
Director Ben Kyger requested an open item to follow-up with EMC
for a technical assessment on the impacts of this issue on data
quality for the models.
