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.

5 Significant and widespread inundation is occurring along the lower Tidal Potomac and adjacent tidal tributaries. Numerous roads and structures are affected.
3.5 Water covers roads on St. Georges Island, is in yards, and approaching structures. To the east, inundation is occurring at multiple marinas off St. Mary's River, Smith Creek, and Jutland Creek.
3 Yards are flooded on Saint George Island, and water will begin covering the road leading to the island, especially if there is wave action.
2.7 Water begins to go over a portion of the bulkhead near the Straits Point bridge, and also covers yards in the St Georges Creek and St Marys River areas.
