Web Portal Changes: The Advanced Hydrologic Prediction Service (AHPS) hosted at https://water.weather.gov will be replaced by the National Water Prediction Service (NWPS), with a target of Spring 2024. Existing AHPS content and features will be preserved and expanded within NWPS. The NWS is now accepting feedback on NWPS. Please visit https://www.weather.gov/owp/operations for more information.

Experimental National Water Center Products: Flood Inundation Mapping services are now available for 10% of the U.S. population. Please visit https://www.weather.gov/owp/operations for more information. The National Hydrologic Discussion, Area Hydrologic Discussion, Flood Hazard Outlook, and real-time geospatial services depicting River Forecast Center and National Water Model forecasts, continue to be accessible via the URL above, as described in the StoryMap here.

25 FEMA 0.2 percent flood level.
24 Major flooding in Westbrook. Inundation is around the FEMA 1 percent flood level. Floodwaters cover Route 302 cutting off access between Portland and Westbrook, inundating several businesses and homes on the north side of the river. Flooding to properties along Riverside Street incuding storage buildings. Materials should be moved to higher ground. This is a dangerous situation.
23 Backwater from Mill Brook floods properties off Forest Avenue and East Bridge Street in Westbrook.
22 Forest Avenue in Portland and Bridgton Road in Westbrook cut off by floodwaters. Water up to properties along River Street in Westbrook. The flood level is comparable to that of Hurricane Bob in 1991.
21 Flooding along Route 302 and East Bridge Street in Westbrook. Water Street flooded near Mentor Street with residential properties impacted.
16 Minor flooding with water encroaching upon East Bridge Street in Westbrook and Route 302. Riverbank Park in Westbrook floods. Sappi Wastewater Drive access cut off by floodwaters.
15 Minor flooding affects storage yards of industrial businesses on Warren Avenue in Westbrook. Property should be relocated to places which are 5 feet higher than nearby river banks to avoid being flooded or isolated.
14 Water approaches the backyards of properties along Water Street in Westbrook and Riverside Street in Portland.
12.5 River comes out of its banks and floods portions of Fraser Field. High flows make recreational activities hazardous.
