On Sunday, November 17, 2013, Unisys Weather in Malvern, PA hosted a group of Girl Scouts competing in the FIRST LEGO League 2013 Nature’s Fury Challenge. The scouts were interested in how Doppler weather radar is used to detect and track tornadoes, and how this information is sent to the public. Unisys senior product engineer Mark Logan and weather program manager Brian Hughes displayed radar images generated by Unisys showing the powerful tornadoes that struck Moore and El Reno, OK in early 2013. In addition, the scouts were able to see “live” imagery of a tornado outbreak over Illinois and Kentucky.
UPDATE 11/4/13, 18:30 UTC: Due to this morning’s NOAAPort product outage, some of the 12Z model runs on Unisys Weather are showing blank images. We are currently going through the images and manually running the programs in order to correct the “blank” plots. Note: Customers subscribed to Unisys Weather Services are not affected by the NOAAPort product outage, as our OpsNet direct connection with the NWS Telecommunications Gateway was not affected.
UPDATE 11/4/13, 16:45 UTC: The NWS has switched the NOAAPort SBN uplink ( http://weather.noaa.gov/tgstatus/ ). Products have re-started on the NOAAPort service as of 16:30 UTC.
Unisys Weather Operations has detected an outage of the products on the NWS NOAAPort broadcast starting at 11:00am EST (16:00 UTC) on Monday, November 4, 2013. Unisys has been in contact with the NWS Network Control Facility (NCF) and is awaiting an update. This outage does not affect customers using the Unisys NOAAPort 5th channel.
Unisys has restored the 10-day GFS maps for Europe, South America, Australia, and East Asia. These maps restore the original 10-day forecast maps, and the “9 panel” GFS overview. Users may notice the GFS maps for days 8.5 through 10 will have a lower resolution of the plotted variables. This is due to the change in resolution to the GFS model after the 192 hour forecast.
Effective with the 1200 UTC run on July 25, 2013, the NWS transitioned the operational production of the weather models to the new Weather and Climate Operational Supercomputing System (WCOSS) system. See official notification for this change.
This switch has caused a shift in model delivery, and may be affecting Unisys weather processing for the models on the Unisys Weather site. We are analyzing the new delivery times, and making adjustments to the scripts to ensure the models are processed correctly. We are aware of the issues with the RAP model graphics production.
Unisys Weather experienced a major outage with our internet provider on Monday, June 10 at approximately 5:45pm EDT. An issue was identified with a major fiber optic cable in the Philadelphia area, knocking out access to our web servers including several data servers at the WeatherMax. Unisys data distribution on our backup circuits and satellite broadcast were not affected. Access was restored at around 5:40am EDT on Thursday, June 11. Customers are advised to use the toll free support phone number to report issues, as this outage also affected e-mail services.
