On Saturday at 3:16 a.m. the National Weather Service issued a coastal flood warning valid for Saturday between 6 a.m. and 10 a.m. The warning is for Coastal Bryan and Coastal Chatham as well as Liberty and McIntosh counties.
"One to two feet of inundation above ground level expected along shorelines and tidal waterways (10.4 to 10.6 feet Mean Lower Low Water at Fort Pulaski)," states the NWS. "High tide will occur around 8 a.m. this morning at Fort Pulaski. Saltwater inundation will be possible 1 to 2 hours before and after high tide."
"Numerous roads will be flooded, along with some properties. Highway 80 to Tybee Island will be impassable," describes the NWS. "Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth."
Understanding the differences between 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 doesn't guarantee that flooding will occur, but it signifies that the possibility exists.
When floods strike: Guidelines from the NWS for your protection
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 NWS 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:
When local authorities issue an evacuation order, promptly comply. Before 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.
Avoid 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.
Stay away from floodwaters:
Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock 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 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 NWS. Prioritize your safety by staying informed and prepared.
