The extremely dangerous heat wave continues across the East Coast and much of the South-Central U.S. today. Record high temperatures are expected for some areas especially across the Mid-Atlantic where extreme heat risk conditions reside. There is a Slight Risk (level 2 of 5) of severe thunderstorms today for the northern Mid-Atlantic into portions of southern New England. Read More >
(For Broadcasters) NWWS is one of two NWS dissemination systems that can activate the local Emergency Alert System (EAS). NOAA Weather Radio All Hazards (NWR) is the other system.
SATELLITE: NWWS product stream is available over NWS Satellite Broadcast Network (SBN/NOAAPORT) Channel 201 using a 1.8m or above satellite dish and receiver configuration; and
INTERNET: NWWS product stream is available over the “Open Interface” (NWWS-OI); requiring user_ID and password issued by NWS and an XML / XMPP software client reader (either developed or commercially purchased).
NOTE: All NWS products can be received via the Internet via FTP and over the SBN/NOAAPORT Channels 101-108.
See Product Dissemination (https://www.weather.gov/NWWS/dissemination for additional alerts and warnings dissemination methods available to the public.
All Users are recommended to use both SBN/NOAAPORT Channel 201 via 1.2m dish or greater, with a low noise band filter, and satellite receiver unit, and the NWWS Open Interface (NWWS-OI) via the Internet for high product availability using a NWS issued user_ID and password through an XML/XMPP client (developed of purchased commercially).
NWWS products start as text-based messages using the World Meteorological Organization (WMO) standard format (https://www.weather.gov/tg/head/). Most NWS dissemination methods leave the NWWS product format unchanged. However, the NWWS-OI is in XML/XMPP format allowing all identified users to access the product stream via a one-way chatroom based on a XMPP client.
See https://xmpp.org/software/clients.html.
See Product Dissemination (https://www.weather.gov/NWWS) for additional methods and formats.
The 75 word per minute NWWS landline system was discontinued on October 11, 1989. The first computer system was developed by ConTel ASC in 1989. ConTel merged with GTE in 1991. The latest NWWS system was designed, developed, and leased from Computer Science Corporation (CSC) from 1999 to 2015.
The current NWS enterprise solution became operational July 1, 2015.
Common Alert Protocol (CAP) version 1.2 is available experimentally. It's currently a WMO header wrapped message on SBN/NOAAPORT PID 101-108 only.

Additional development is in process to place CAP v1.2 on https://alerts.weather.gov. Implementation Date - TBD
More information on CAP v1.2 can be found at http://docs.oasis-open.org/emergency/cap/v1.2/CAP-v1.2.html
NWWS products are also available over the Internet via NWS anonymous FTP, via NOAA Weather Radio All Hazards (NWR), telephone, pager, and via commercial provider(s).

PROBLEM: If you did not completely exit the XMPP program before shutting down, a “phantom” account will continue to exist. This “phantom” account will prevent you logging into the NWWS-OI. Do not ask for account reset. RECOMMENDED SOLUTION: Empty the cache and then log back in using the assigned user_ID and password.
