Here is today's summary of NHC computer operations:
--- Craig Mattocks
1. N-AWIPS issues: Yesterday's 15Z danger graphic for TD Two-E did not have
the wind speed probabilities (WSPs) overlaid on it. This was an unintended
consequence of turning off the legacy script that generates the WSP web
graphics, which also creates the Gempak WSP files. Dave Zelinsky turned the
legacy crontab entry back on and edited out the send-to-web calls to fix
2. GFE/NCP issues: None of the three forecasters on-shift could not log
into the Collaboration server. Trouble Ticket #136877 was opened with NCF
yesterday. Lead Forecaster Jeff Lewitsky began troubleshooting with the
NCF. The NCF told TAFB to select "chat-ncf" as the server when logging in,
instead of "Primary chat2-ncf". Forecasters could not enter the "marine"
chat room because that bookmark also pointed to "chat2-ncf". All users
should remove that bookmark by right-clicking on it, then selecting the
upside-down reveal triangle "Public Room Search" and right-click
on "marine" to add a new/correct bookmark.
3. Nearshore Wave Prediction System (NWPS): The swing shift yesterday
reported that the 18Z run for the Atlantic/NH2 domain did not complete or
return to GFE. Investigation revealed that the 18Z run came into AWIPS/GFE
at 0700Z today (about 14 hours after it was triggered). The 00Z run,
triggered on the midshift, had no trouble. The 12Z run, triggered this
morning at 11Z, has not completed or come into GFE. These problems are
probably caused by Storm Surge Unit activity on the sardine server - very
few CPU cores available for the Swan wave model. TSB is researching other
computational platforms on which to deploy the NWPS.
4. An accelerated RFC was implemented by NCO yesterday at 1604Z to upgrade
the Ballyhoo N-AWIPS workstation to the same graphics driver and system
configuration as the Cumulus N-AWIPS workstation.
5. Miscellaneous issues: The Storm Surge Unit is using the debout standing
workstation for innundation graphic creation during the ongoing national
TCV and storm surge watch/warning collaboration testing.
1. ATCF issues: The wind radii guidance was slow to appear for the 15Z
package yesterday, but was on time for the 21Z package.
2. ATCF issues: The EGRI (UK Met Office model, 6-hr interpolated) track is
not in the ATCF. Appears that this occurred much of yesterday.
Senior Hurricane Specialist Mike Brennan investigated and determined that
the 12Z EGRR text tracker (see the GTS bulletin below) dropped TD Two-E
before 12 hours, so the EGRI/2 trackers did not show up yesterday

The tracker output should be available in the ATCF now since the 00Z run
carried the storm out farther in time.
3. ATCF issues: The 18Z HWRF track only showed the initial location of the
system with no track thereafter, despite the model showing a coherent
Mike Brennan determined that the 18Z HWRF tracker dropped TD Two-E after
the initial time, so the HWFI (HWRF-interpolated) tracker was missing at
00Z last night:
EP, 02, 2017053118, 03, HWRF, 000, 135N, 980W, 33, 1004, XX, 34, NEQ, 0000,
0000, 0000, 0000, -99, -99, 139, 0
It has been carrying the storm a little longer in subsequent cycles, but
the 06Z only goes out to 42 hours. See the TC Vitals file:
This is probably due to a detection rule violation in Tim Marchok's tracker
software - it is not able to follow a shallow/weak storm or one with a
large horizontal displacement across multiple vertical levels (severe tilt,
lack of vertical coherence).
4. Miscellaneous issues: The TC Graphics at 03Z were run immediately after
the TCM was issued. It plotted the new forecast but showed the old time and
previous watch area. Reran at 0240z.
TSB Developer Dave Zelinsky reminded the Hurricane Specialists that the TCM
(forecast advisory) and TCP (public advisory) are required inputs to the TC
graphics, so both must be transmitted before the TC graphics can be run.
This is not new in 2017.
1. NESDIS STAR IT completed its network maintenance and is in the process
of resuming normal data flows. Himawari-8 and METEOSAT IODC distribution
expected to begin around 13:00 EDT; back-filled data to take a little while
1. Adjust route filtering on the NCEP core network to allow the routes for
the Hurricane Hotline to reach the Alaska Region. To be implemented on
Thursday, June 8 at 1900Z (3 pm EDT).
2. On WCOSS, add new project codes HMON-T2O and HMON-OPS to allow jobs for
the new HMON (Hurricanes in a Multi-scale Ocean-coupled Non-hydrostatic)
model to be run with their own accounting codes. To be implemented on
Tuesday, June 6 at 1600Z (noon EDT) on the WCOSS production supercomputing
