Powerful Pacific System Impacting the West; First Significant Snow for Portions of the East

Power Pacific system will continue to bring significant impacts for Pacific Northwest into northern California the remainder of the week. Dangerous coastal affects, heavy rain, flooding, strong winds, and higher elevation mountain snow continues. Meanwhile, a storm across the east is set to bring the first accumulating snow to many higher elevations of the Catskills into the central Appalachians. Read More >

BEHIND THE SCENES

This may look like nothing more than a room full of mainframe computers, and you'd be right! Hidden in a room located behind the operations floor are the "brains" behind the computers. There are two such rows. The mainframe computers powering AWIPS can be seen here. The other row contains the computing power for the WSR-88D radar.

You may wonder how we receive data or transmit the items we produce. The secret lies in the satellite dish seen below, on the right. This dish lives in our "backyard" and is our data connection to the world. All data entering or leaving the Weather Service travels by satellite through the Control Facility in Silver Spring, MD. The path the item takes varies slightly for outgoing and incoming items. For products we issue, after we compose and send it, it travels to the local River Forecast Center (RFC; for us, State College, PA or its backup site in Taunton, MA), through the Network Control Facility (NCF), and then through Telecommunications Gateway in Suitland, MD. Most incoming data comes straight from the NCF to all local Forecast Offices. Radar data and some local observations are exceptions; they too get funneled through the servicing RFC. In all cases, the data is bounced off satellites high above Earth each step of the way. Yet, data makes it between us and its destination in a couple of minutes. Our close proximity to the national transmittal source doesn't significantly reduce transmission time-- it might take a few seconds less for us. It truly is quite remarkable to think of how far and how fast the data travels.
