It appears that some satellite imagery has been restored, but that the feed of satellite data used for models remains somewhat incomplete. “The last update I received was that we are not yet fully restored, but there has been some improvement in datasets for the models,” said Chris Vaccaro, National Weather Service spokesperson. A technical notice from the National Weather Service stated the “majority” of satellite data has become available for the models.
Since at least Tuesday, some satellite data – an important input to weather prediction models – has stopped flowing into the National Weather Service due to an apparent network outage.
At 1 p.m. today, the National Weather Service’s National Center for Environmental Prediction (NCEP) issued the following statement cautioning the outage could impact forecast quality:
NCEP HAS NOT RECEIVED A FULL FEED OF SATELLITE DATA FOR INPUT INTO THE NUMERICAL MODELS SINCE 22/0000Z…POTENTIALLY IMPACTING THE MODEL FORECASTS.NESDIS AND NCEP ARE INVESTIGATING THE ROOT CAUSE OF THE ISSUE. ONCE THE SITUATION IS RESOLVED ANOTHER MESSAGE WILL FOLLOW.
