Monsoonal moisture will produce showers and thunderstorms with heavy rain over parts of the Southwest, Great Basin, and Central Rockies through Monday. Flash flooding is possible, especially in and around burn scars and in areas of steep terrain. Heat will persist across the Central U.S. early this week, spreading into the Ohio Valley and Mid-Atlantic later this week. Read More >
Satellite broadcast is one method used by the NWS and others for disseminating the EMWIN data stream. Our goal is to make the data stream available nationwide, but not to provide detailed support (i.e. funding, manpower, or equipment) for state and local efforts to redistribute the data stream after down link.
The NWS broadcasts EMWIN on NOAA's GOES East and GOES West satellites. GOES East is at 75 degrees West, elevation 45 degrees (from the latitude of Washington, DC). GOES West is at 135 degrees West. Data is uplinked to satellite from the NOAA Command and Data Acquisition (CDA) Station on Wallops Island, VA.
The GOES downlink frequency for the EMWIN datastream is 1692.7 MHz. This broadcast is 19.2 kbps, using offset QPSK modulation with forward error correction.
The EMWIN data stream is also currently uplinked to the Telstar 5 Satellite, located at 97 degrees West. The center frequency of the Telstar 5 EMWIN signal is 12,185 MHz, subcarrier frequency is 1.065 MHz.
