Here is today's summary of NHC computer operations:
--- Craig Mattocks


1. In an effort to comply with mixed-case text guidelines, TAFB forecasters  
began issuing the Tropical Weather Discussions (TWDAT and TWDEP products)  
with a mixed-case Mass News Disseminator (MND) header block, eg:

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
752 PM EDT SUN JUN 5 2016

Note that the issuance date/time line must remain in ALL-CAPS until AWIPS  
build 16.2.2 is installed due to an incompatibility with NWRWAVES (NOAA  
Weather Radio With AllHazards VTEC Enhanced Software).

Unfortunately, this change in the product headers cused a text parsing  
error so the products could not be displayed correctly on NHC's web site.  
TSB Web Developer Dave Zelinsky had to scramble on a weekend to fix the  

Forecasters are advised to coordinate with TSB before making any changes  
like this.

2. TAFB forecasters reported that the surface progs would not launch from  
the Cumulus N-AWIPS workstation at 06Z on Saturday, June 4 (workstation  
hung up). They were successfully launched from Crappie. After rebooting the  
Cumulus workstation, the scripts began running fine.

3. The OFFN04 (NAVTEX marine forecast, Miami) product crashed several times  
for 5:30 am issuances. To work around this problem, the previous version  
was retransmitted and the time was changed. TAFB Surface Anayst Evelyn  
Rivera-Acevedo discovered that the weather type "SQ" (squall) was not  
defined in the wxHierarchies() function/def in the GFE Python script for  
this product. She added it to the function, which corrected the problem.
1. There have been multiple problems importing the EMX/EMXI/GFSI forecast  
aids in the ATCF during TS Colin. This is a NCEP problem, caused by the  
Marchok vortex tracker not being able to locate the center of the weak,  
disorganized storm.

2. The SST anomaly plots on NHC's web site:


did not compare well with those on the Climate Prediction Center's web site:


TSB Developer Matt Overlinde discovered that the average SST needed to be  
computed for the middle (15th day) of the month, instead of the first of  
the month. This correction remedied the cold bias in the western Atlantic.  
The SST anomalies in the NHC product are now in much better agreement with  
those computed by CPC.

3. Noise problems continue with the Hurricane Hotline, despite recent work  
by AT&T technicians in Silver Spring. NCO is monitoring thia issue.

4. Web-launch errors occurred for social media products due to a missing  
account on the backup web server (hsu at nhc-vm-www02). A different, shared  
account was used, so the product successfully posted to the web. TSB Web  
Developer Dave Zelinsky and NCO SysAdmin Brian Maher fixed this problem.

5. RSO (Rapid Scan Operations) satellite imagery is still not available.  
TSB Developer Monica Bozeman will create a McIDAS alias that points to the  
NESDIS location in order to ingest the imagery.
