The National Weather Service issued an updated flood watch at 9:45 p.m. on Tuesday in effect until Friday at 8 a.m. for Dillon, Florence, Marion, Williamsburg, Horry and Georgetown counties.
The weather service comments, “Flash flooding caused by excessive rainfall continues to be possible.”
“Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations,” adds the weather service. “Be especially cautious at night when it is harder to recognize the dangers of flooding.”
This watch is in effect until Friday at 8 a.m.
Breaking down weather alerts: advisories, watches, and warnings
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 warning: Take action!
A flood warning is issued when flooding is imminent or occurring.
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.
Flood watch: Be prepared:
A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.
Be flood-ready: Expert guidance from the weather service for your safety
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:
Move to higher ground: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.
Adhere to evacuation orders:If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.
Disconnect utilities and appliances:If time allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.
Steer clear of flooded basements and submerged areas:Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.
Swift evacuation for your safety: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.
Refrain from walking in floodwaters:Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.
Seek higher ground when trapped: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 heavy rain, flooding is possible, especially in low-lying and flood-prone areas. Never drive through water on the road, even if it does not appear to be deep. It takes just 12 inches of rushing water to carry away most cars, according to the weather service. Stay safe by being prepared and informed.
Rainy roadways ahead: Essential safety tips for heavy rain
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:
Beware of rapid water flow:In heavy rain, refrain from parking or walking near culverts or drainage ditches, where swift-moving water can pose a grave danger.
Maintain safe driving distances:Adhere to the two-second rule for maintaining a safe following distance behind the vehicle in front of you. In heavy rain, allow an additional two seconds of distance to compensate for reduced traction and braking effectiveness.
Slow down and drive with care:If it is raining and the roads are wet, slow down. Take your foot off the accelerator and let your speed drop gradually. Never use the brakes suddenly because this may cause the car to skid.
Choose your lane wisely:Stick to the middle lanes on multi-lane roads to minimize the risk of hydroplaning, as water tends to accumulate in outer lanes.
Visibility matters:Enhance your visibility in heavy rain by turning on your headlights. Watch out for vehicles in blind spots, as rain-smeared windows can obscure them.
Watch out for slippery roads: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.
Keep a safe distance from large vehicles:Don’t 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 quickly and safely.
Mind your windshield wipers: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.
By following these safety measures, you can significantly reduce risks and ensure your well-being when heavy rain pours down. Stay informed about weather conditions and heed advice from local authorities to make your journey safe and sound.
