An updated coastal flood advisory was issued by the National Weather Service on Thursday at 5:46 a.m. valid for Thursday between 1 p.m. and 4 p.m. for Horry and Georgetown counties.
“Up to one half foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways,” explains the weather service. “Affected areas listed are based on average tide conditions. Additional locations may experience flooding during periods of heavy rainfall, high winds, or other factors.”
“Vulnerable causeways to and from local beaches may experience minor coastal flooding. Low-lying roads and locations along the Intracoastal Waterway and adjacent tidal creeks may observe minor coastal flooding. Check with local officials for the latest information regarding coastal flood impacts and closures. Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water,” states the weather service. “If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. Swim near a lifeguard. If caught in a rip current, relax and float. Don’t swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.”
This advisory is in effect until 4 p.m.
Understanding the differences between advisories, watches, and warnings
Flash flood warning: Take action!
A flash flood warning is issued when a flash flood is either imminent or already occurring. In flood-prone areas, it’s crucial to move immediately to higher ground. A flash flood is a sudden and violent inundation that can develop within minutes to hours, and it can even happen in areas not currently experiencing rainfall.
Flood warning: Take action!
A flood warning is issued when flooding is imminent or occurring.
Flood advisory: Be aware:
A flood advisory is issued when flooding is not expected to be bad enough to issue a warning. However, it may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may 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
In flood-prone regions or while camping in low-lying areas, understanding and following the weather service flood safety guidelines can be a lifesaver:
Seek 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 permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.
Avoid basements and submerged areas:Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.
Swift evacuation for your safety:If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity.
Stay away from floodwaters:Never attempt to walk through floodwaters, even if they appear shallow. Just 6 inches of fast-moving water can forcefully sweep you off your feet.
Seek high ground if trapped:Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.
During periods of heavy rainfall, especially in low-lying and flood-prone areas, the risk of flooding escalates. Remember this crucial advice: never attempt to drive through water on the road, even if it appears shallow. According to the weather service, as little as 12 inches of rapidly flowing water can carry away most vehicles. Prioritize your safety by staying informed and prepared.
