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


1. GFE/NCP issues: Matt Sardi worked with Jeff Lewitsky to troubleshoot the  
issue of RWPS model results not appearing in GFE/D2D for both the Atlantic  
and Pacific domains. Matt confirmed the data was available on the EMC Polar  
server (polar.ncep.noaa.gov). He ran things from the command line and  
successfully pulled in the data for both basins. Thus, the issue appears to  
be with the crons. He will monitor the dataflow on Friday (after adding  
enhanced logging to the ingest scripts) and make changes to the cron if the  
current setup that he modified does not work.

2. GFE/NCP issues: Update - the pre-Wind Speed Probabilities for 06z  
successfully came in at 0830Z.
1. AWIPS-2/NCP issues: HSU encountered MAJOR problems with the National TCV  
at 5, 8 and 11 pm as indicated in the HSU shift log. HSU had another  
incident where erroneous forecast zones were added to the national TCV (WFO  
El Paso's EPZ zone this time), as well as problems running StormInfo and  
other National TCV procedures. For the 5 pm TCV, HSU called NCF (who  
elevated the zone issue to their programmers). Shannon White once again  
removed the erroneous grids, allowing HSU to rerun the formatter and  
transmit a correct version.

TSB Developer Dave Zelinsky updated critical NCF ticket #139509 and opened  
a new critical ticket (#139894) on the StormInfo errors/problems (the tool  
wouldn't run) reported by the evening shift. He forwarded Shannon White's  
summary as well as Mike Brennan's instructions to HSU regarding the  
National TCV.

Re: National TCV - The problems running StormInfo are user error. If  
forecasters don't click on the now/future part ISC grid to make it "active"  
before running storm info, it will fail.

2. The Time of Arrival (ToA) graphic for Advisory 9 had a contour off the  
Delmarva coast, which none of the other advisories did. Because the  
forecast winds reached the coast, the wind speed probabilities exceeded 5%  
there. The graphic was designed to include any probabilities greater than  

3. N-AWIPS issues: Product generation won't open/NMAP window crashes when  
trying to click product generation on the Pacific N-AWIPS workstation  
(Sawfish). Cannot create the watch/warning graphic on that workstation. TSB  
will investigate.

4. N-AWIPS issues: Ridges workstation had a temporary lock-up caused by a  
sudden surge of CPU activity. Cause of the CPU surge is unknown.

5. ATCF issues: A remote user complained of an error in the alignment of  
the wind radii values in the TCM (Forecast Advisory) during TS Cindy. TSB  
Developer Craig Mattocks will work on correcting this error.
Other items:
1. ECMWF model data outage (paraphrased from the SDM's log): At 1007Z  
yesterday, NHC's Dave Zelinsky inquired about the missing 00Z ECMWF data.  
SDM notified him of the current ECMWF production issues. ... ECMWF reported  
that they had file system problems on one of their dissemination servers.  
They took the server out of operations, and re-transmitted all products  
that were problematic. This caused a 1-hour delay in delivery of the model  
1. Accelerated RFC 242 - Added Southern Region (SR) Hurricane Threats and  
Impacts (HTI) graphics to local products page. Edited HLS (Hurricane Local  
Statement) processing to add a link to the new SR HTI graphics and local  
portals to the "NWS Local Products" page. Removed link to the old HTI  
webpage. Implemented on Monday, June 19 at 1500Z (11 am EDT).

2. RFC 243 - Update to tc_graphics package to better handle intermediate  
upgrade of a Potential Tropical Cyclone. When TCs are upgraded  
from "Potential Tropical Cyclone" to "Tropical Storm" an additional check  
in the code is required so that the existing wind radii information can be  
used. To be implemented on Monday, June 26 at 1300Z (9 am EDT).

3. RFC 3403 - Upgrade bandwidth of NHC current circuits (ETH1000C2-17095291  
& ETH1000C1-17095304) from 200Mbs to 1Gbs. Centurylink will perform a  
provider side bandwidth increase on the existing circuit. There is a  
possibility of service interruption/degradation during two 20-minute  
windows (1530Z - 1550Z and 1620Z to 1640Z), even though there are two  
circuits, since NCO will have to manually transition a circuit to standby  
state before the upgrade is performed. Route convergence will occur during  
this process which might cause traffic to be dropped during the transition  
which will require sessions to be re-established. Was to be implemented on  
Tuesday, June 20 at 1530Z; postponed to Wednesday, June 28 at 1500Z (11 am  

4. RFC 3437 - At NHC's request, add alerts to send the Wind Speed  
Probability North America 0.5 degree AWIPS grid files  
tpcprblty.YYYYMMDDHH.g231.2 and tpcprblty.YYYYMMDDHH.g231.2.grib. Was to be  
implemented on Tuesday, June 20 at 1410Z; postponed due to CWD until  
Thursday, June 22 at 1400Z (10 am EDT).

5. Implement Storm Surge Watch Warning (SSWW) and Tropical expressions of  
uncertainty updates to the following applications on weather.gov:
- forecast-v3
- alerts-v2
- api
- forecast
- alerts
- wwamap
This RFC may be accelerated for implementation on Thursday, June 22 (time  
TBD but will not occur until after CWD ends at 1200Z/8 am EDT on Thursday,  
June 22).
