NWWS is a
satellite data collection and dissemination system operated by
the National Weather Service
(NWS). Its purpose is to provide state and federal
government, commercial users, media, and private citizens with
timely delivery of meteorological, hydrological, climatological,
and geophysical information. The vast majority of
NWWS products are weather and hydrologic
forecasts and warnings issued around the clock from 141 NWS offices
nationwide (see Product
Collection and Dissemination).
element of the NWWS mission is providing rapid
delivery of critical NWS issued severe weather warnings and watches.
All products in the NWWS datastream are prioritized, with weather
and hydrologic warnings receiving the highest priority (watches
are next in priority). This allows special handling
and delivery of warning products ahead of other less critical
weather forecast products. NWWS delivers severe weather
and storm warnings to users in 10 seconds or less from
the time they are issued, making it the fastest delivery
system available for these very time sensitive products.
Administration, maintenance, and field support is provided by
Information Systems LLC, under NWS contract.
