"Flash flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as other poor drainage and low-lying areas." Locations impacted by the warning include Lancaster, Columbia, Millersville, Willow Street, East Petersburg, Paradise, Salunga-Landisville, Strasburg, Mountville, Smithville, Safe Harbor, Lampeter, Intercourse, Conestoga, Washington Boro, Gordonville, Bird-In-Hand, Smoketown, Refton and Millersville University. According to the weather service, "Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. 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.Floods can pose a significant threat, especially if you live in a flood-prone area or find yourself camping in a low-lying region. To ensure your safety, the weather service offers essential flood safety guidelines:If you're in a flood-prone area, or if you're camping in a low-lying spot, move to higher ground as a first step.If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity.Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.In the event you become trapped by moving water, make your way to the highest point available and contact emergency services by calling 911. During periods of intense rainfall, the risk of flooding increases, particularly in low-lying and flood-prone areas. It is imperative to avoid driving through any water on the road, even if it seems shallow. According to the weather service, most cars can be swept away by just 12 inches of rushing water. Prioritize your safety by staying informed and prepared.When heavy rain strikes, safety is paramount. Equip yourself with these guidelines from the weather service to navigate wet roads and avoid hazards:During heavy rain, avoid parking or walking near culverts or drainage ditches, where swift-moving water can pose a serious risk.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, slowing down is paramount. Gradually ease off the accelerator 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.Turn on your headlights and be careful of other vehicles to the rear and in blind spot areas as they are especially difficult to see through rain-spattered windows.The initial half-hour of rain is when roads are slickest due to a mixture 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.Overloaded wiper blades can hinder visibility. If rain severely impairs your vision, pull over and wait for conditions to improve. Seek refuge at rest areas or sheltered spots. 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. In the face of heavy rain, these precautions can make a significant difference in ensuring your safety on the road. Remember to stay informed about weather conditions and heed guidance from local authorities for a secure journey.
