Residents across Pennsylvania are urged to exercise caution due to elevated wildfire risks prompted by a combination of dry and breezy conditions. The National Weather Service has reported that relative humidity levels may drop as low as 20 to 25 percent, with westerly winds gusting up to 25 mph. This critical fire weather affects Central Pennsylvania, including the Northern and Western Mountains, the Susquehanna Valley, parts of Northeastern Pennsylvania, and portions of Southeast Pennsylvania. Cities and towns within these regions should remain alert, avoid outdoor burning, and extinguish potential ignition sources like cigarettes. The increased fire danger is expected to persist throughout the afternoon and into the early evening. Residents are encouraged to check the Pennsylvania Department of Conservation and Natural Resources website for more information on wildfire prevention.

Pennsylvania experiences a humid continental climate with average precipitation of around 42 inches per year. Major surface flows include the Susquehanna River, Delaware River, and Ohio River. The Susquehanna River Basin encompasses 27,500 square miles and is home to numerous reservoirs and dams including the Conowingo Dam and Raystown Lake. Major tributaries of the Susquehanna include the Juniata River and West Branch Susquehanna River. The Delaware River Basin spans multiple states and contains several reservoirs and dams, such as the Francis E. Walter Dam and Beltzville Lake. The Ohio River Basin covers parts of western Pennsylvania and includes the Allegheny River and Monongahela River. Watershed and snowpack data can impact hydrology in these areas, particularly in relation to flooding and drought conditions.
