ALERT: Update on status of the nationwide data transmission error that prevents stream gauge data collected at affected locations from being displayed on the Advanced Hydrologic Prediction Services (AHPS) webpages. The USGS has restored the transmission from all of their gauges or has placed them in a seasonal outage (some Alaska gauges). There are a few USGS gauges that the NWS is not yet receiving the new transmissions and NWS is working to get that data by alternate means. A map of the status of USGS gauges is here. The status map of gauge outages from other agencies is here. The situation has greatly improved and will continue to improve but at a slower pace. The outage maps will now be updated once per week on Thursday. We apologize for the service interruption and hope to have the data restored as soon as possible.

The lowest homes in the flood plain are threatened near Vienna and in northern Jackson County. Livestock should be removed from the flood plain from the headwaters to Lake Texana.
30	Moderate lowland flooding occurs as water inundates County Road 283. Livestock could be cut off and should be removed from the flood plain.
29	Minor lowland flooding begins as water reaches the right approach to the bridge at County Road 283. Livestock should be removed from vulnerable areas of the flood plain.
26	Overbank conditions begin with water into low areas of the flood plain with little damage.
19	Flow exceeds banks into lowest areas of the flood plain with no damage.
