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.

Why aren't the FEMA National Flood Hazard Layers showing on the ESRI Map? Possible reasons: There are no FEMA National Flood Hazard Layers for the location which you are viewing on ESRI Maps. The FEMA Web Mapping Service (WMS) is down. Note: Your zoom level may have changed. ESRI's zoom levels must be between 14 and 16 to show National Flood Hazard layers.

38	The river level will be overtopping the levee protecting the town of Orick and adjacent areas. The entire delta area from Prairie Creek downstream to the mouth will be innundated. Travel through the area will be severely restricted with numerous road closures, including Highway 101. All persons in the area should take appropriate action to protect life and property, and move to higher ground as necessary.
37	The river level is at the top of the levee protecting the town of Orick and adjacent areas. Many roads in the delta area may be flooded and impassable including Highway 101. All persons in the area should take appropriate action and move to higher ground if necessary. High tides and strong onshore winds will amplify effects.
36	The river is within 1 foot of top of levee. Flooding of some roads in the Orick area is likely. Persons living or working in areas protected by the levee should be prepared to take appropriate action and move to higher ground if necessary. High tides and strong, onshore winds amplify effects.
35	The river is within 2 feet of the top of the levee. Flooding of roads in the Orick area is possible. Persons living or working in areas protected by the levee should be prepared to take appropriate action and move to higher ground if necessary. High tides and strong, onshore winds amplify effects.
