In a follow-up statement Monday, Buchanan said the communications delay
resulted from a damaged fiber optic cable at the Weather Service’s
Dallas-Fort Worth office.
“The cable outage caused that office to switch from its primary,
land-based communication network to a backup satellite-based network that
serves every NWS field office,” she wrote. “The uptick in messages flowing
to the central message handler from NWS Central Region offices due to the
severe weather, combined with the performance characteristics of the
satellite network in use at a co-located site, slowed down the queue of
message transmissions and created a brief backlog across multiple
offices.”
