Excessive heat warnings persist across the Desert Southwest, while the heat and humidity lingers along the East Coast. An extensive zone of strong to severe thunderstorms with damaging winds and locally heavy rain are expected along a strong cold front from New England to the south-central Plains. Finally, elevated fire weather threats/red flag warnings are likely across the Inter-mountain West. Read More >

| Background Information |
The Hydrologic Services Area (HSA) encompasses portions of four states: Western Pennsylvania The northern panhandle of northern West Virginia East Central Ohio Garrett County Maryland
The Monongahela, Allegheny and Upper Ohio River are the primary streams in this HSA. These form the headwaters of the Ohio River. Major tributaries include the Beaver, Clarion, Cheat, and Youghiogheny Rivers. In December 1994, the Pittsburgh HSA added most of the Muskingum River basin in East Central Ohio to its HSA.
HSA rivers flow through many heavily-populated river valleys, including the city of Pittsburgh. Pittsburgh is the largest inland port in the nation. When seaports are considered, Pittsburgh ranks 11th. Commercial barge traffic on the primary streams has a significant impact on the economy of the four-state region. According to a Port of Pittsburgh Commission study released in July 1996, these rivers generate nearly 120,000 jobs and $5.2 billion in wages annually.
Most commonly, hydrologic problems occur when heavy rain falls over moderately steep/mountainous headwater areas, resulting in flash flooding in narrow, populated valleys. Among the nation's fastest responding mainstem river systems, flooding on the HSA's rivers occurs when synoptic-scale systems bring widespread rainfall. Ice jams and moderate rainfall on snow during the cooler months can also produce significant flooding.
The Pittsburgh HSA has over forty forecast points. Forecast guidance is provided by the Ohio River Forecast Center (OHRFC) in Wilmington, Ohio. In addition to daily river stage forecasts, the Pittsburgh Forecast Office issues River Ice Statements at least twice weekly during ice season.
The following graphics show all the forecast points that we forecasts stages for on a daily basis.

River Ice Jams are also a big problem on the Allegheny River in the winter and spring. Check out ourAllegheny River Ice Jam Map
