Urgent for you to know:
- Due to an operational issue with data transmission from the GOES-East satellite, real-time data including streamflow is not transmitting for approximately 25-30% of sites, primarily in the eastern portion of the U.S. and territories. When the GOES-East satellite transmissions resume, real-time data will begin flowing again to all sites.
