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.<\/p>\n<p>Flood warning: Take action. <\/p>\n<p>A flood warning is declared when flooding is on the verge of happening or is already underway.<\/p>\n<p>Flood advisory: Be aware. <\/p>\n<p>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.<\/p>\n<p>Flood watch: Be prepared. <\/p>\n<p>A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.<\/p>\n<p>Keeping safe during floods: Expert advice from the NWS <\/p>\n<p>In flood-prone regions or while camping in low-lying areas, understanding and following the NWS flood safety guidelines can be a lifesaver:<\/p>\n<p>Seek higher ground:<\/p>\n<p>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.<\/p>\n<p>Adhere to evacuation orders:<\/p>\n<p>When local authorities issue an evacuation order, promptly comply. Before leaving, secure your home by locking it.<\/p>\n<p>Disconnect utilities and appliances:<\/p>\n<p>If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.<\/p>\n<p>Steer clear of flooded basements and submerged areas:<\/p>\n<p>Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.<\/p>\n<p>Evacuate promptly for safety:<\/p>\n<p>If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity.<\/p>\n<p>Refrain from walking in floodwaters:<\/p>\n<p>Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.<\/p>\n<p>Seek higher ground when trapped:<\/p>\n<p>Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.<\/p>\n<p>When heavy rain occurs, there is a risk of flooding, particularly in low-lying and flood-prone regions. It is important to never attempt to drive through water on the road, regardless of how deep it appears. According to the NWS, as little as 12 inches of rushing water can sweep away most vehicles. Prioritize your safety by staying informed and prepared.<\/p>\n<p>Navigating heavy rain: Essential safety measures for wet roads <\/p>\n<p>Rain can turn roads into hazards. Stay informed and follow these tips from the NWS to ensure safety during heavy rainfall:<\/p>\n<p>Beware of swollen waterways:<\/p>\n<p>During heavy rain, avoid parking or walking near culverts or drainage ditches, where swift-moving water can pose a serious risk.<\/p>\n<p>Maintain safe driving distances:<\/p>\n<p>Use the two-second rule to maintain a safe distance from the car in front of you and allow an extra two seconds in heavy rain.<\/p>\n<p>Slow down and drive with care:<\/p>\n<p>On wet roads, slowing down is paramount. Gradually ease off the accelerator and avoid abrupt braking to prevent skidding.<\/p>\n<p>Choose your lane wisely:<\/p>\n<p>Stick to the middle lanes to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.<\/p>\n<p>Visibility matters:<\/p>\n<p>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.<\/p>\n<p>Watch out for slippery roads:<\/p>\n<p>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.<\/p>\n<p>Keep a safe distance from large vehicles:<\/p>\n<p>Don\u2019t follow large trucks or buses too closely. The spray created by their large tires reduces your vision. Take care when passing them as well; if you must pass, do so with caution.<\/p>\n<p>Mind your windshield wipers:<\/p>\n<p>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.<br \/>\nIf the roadside is your only option, pull off as far as possible, preferably past the end of a guard rail, and wait until the storm passes. Keep your headlights on and turn on emergency flashers to alert other drivers of your position.<\/p>\n<p>By following these safety measures, you can significantly reduce risks and ensure your well-being when heavy rain pours down.
