Locations impacted by the warning include Carlisle, Schlusser, Boiling Springs, Mount Holly Springs and Penn State Dickinson School Of Law.

Be aware of your surroundings and do not drive on flooded roads."Flash flood warning: Take action! A flash flood warning is issued when a flash flood is imminent or occurring. If you are in a flood-prone area, move immediately to high ground. A flash flood is a sudden violent flood that can take from minutes to hours to develop. It is even possible to experience a flash flood in areas not immediately receiving rain.Flood advisory: Be aware: A flood advisory is released when flooding is not expected to reach a severity level necessitating a warning. Nonetheless, it can still cause considerable inconvenience and, without exercising caution, potentially lead to situations that threaten life and/or property.A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.In flood-prone regions or while camping in low-lying areas, understanding and following the weather service flood safety guidelines can be a lifesaver:If you reside in a flood-prone region or are camping in low-lying terrain, the first step to safety is relocating to higher ground.If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.If time allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.If you notice sparks or hear buzzing, crackling, snapping, or popping sounds, evacuate without delay. Do not enter water that may carry an electrical charge.Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services. When heavy rain occurs, there is a potential for flooding, particularly in areas that are low-lying or prone to floods. It is crucial to never drive through water on the road, even if it appears shallow. According to the weather service, as little as 12 inches of fast-flowing water can carry away most vehicles. Prioritize your safety by staying informed and prepared.When heavy rain sets in, the risk of flooding and hazardous driving conditions rises. Whether it's prolonged rainfall or rapid runoff, being prepared is essential. Here are some valuable safety tips from the weather service to ensure you stay safe in heavy rain:Avoid parking or walking in close proximity to culverts or drainage ditches, as the swiftly moving water during heavy rain can potentially carry you away.The two-second rule for following distance is your ally in heavy rain. Extend it to four seconds to ensure safe spacing in adverse conditions.On wet roads, reducing your speed is crucial. Ease off the gas pedal gradually and avoid abrupt braking to prevent skidding.Stick to the middle lanes to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.Enhance your visibility in heavy rain by activating your headlights. Be particularly vigilant for vehicles in blind spots, as rain-smeared windows can obscure them.The first half-hour of rain is when roads are slickest due to a mix of rain, grime, and oil. Exercise heightened caution during this period.Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and pass them swiftly and safely.Heavy rain can overload the wiper blades. When visibility is so limited that the edges of the road or other vehicles cannot be seen at a safe distance, it is time to pull over and wait for the rain to ease up. It is best to stop at rest areas or other protected areas. When stopping by the roadside is your only option, position your vehicle as far off the road as possible, ideally beyond guardrails. Keep your headlights on and activate emergency flashers to alert other drivers of your position. By following these safety measures, you can significantly reduce risks and ensure your well-being when heavy rain pours down.
