Low pressure interacting with Zeta will bring widespread heavy rainfall, areas of flooding, and gusty winds from the Ohio Valley to the East Coast. As a coastal storm develops off the Northeast coast on Friday, another round of heavy rainfall is possible for the northern Mid-Atlantic, with wintry precipitation over interior New England.

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.
