The National Weather Service issued a coastal flood warning at 11:18 a.m. on Wednesday valid for Thursday between 1 a.m. and 1 p.m. for Mobile and Baldwin counties.

“Significant coastal flooding expected,” can be expected according to the weather service. “Around 3 feet inundation, water severely impacts portions of Bienville Blvd on the west end of Dauphin Island. Significant flooding with several feet of water on portions of Bienville Blvd. The last three miles of Bienville Blvd becomes impassable and is usually closed at these levels. Water will be underneath numerous homes (most of which are elevated) on the west end of the Island. Parts of the causeway leading to Dauphin Island are often closed due to coastal flooding. Most portions of Shell Belt and Coden Belt Roads are closed and impassable due to flood waters. Fort Morgan Road between mile markers 4 and 6 become flooded. Minor beach erosion along the Gulf beaches occurs, but no significant flooding of normally dry ground occurs.”

“Numerous roads may be closed. Low-lying property including homes, businesses, and some critical infrastructure will be inundated. Some shoreline erosion will occur. Breaking waves can sweep people off jetties and docks, and into dangerous seas. Life-threatening swimming conditions and significant beach erosion can be expected. Rip currents can sweep even the best swimmers away from shore into deeper water,” adds the weather service. “Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Everyone should remain out of the water due to life-threatening surf conditions. Stay off of jetties, piers, and other waterside infrastructure. 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.”

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 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.

Navigating floods: weather service flood safety guidelines for weathering the storm

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:

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.

Follow 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:

Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.

Evacuate promptly for 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 just 6 inches of swiftly moving water can forcefully knock you off your feet.

Seek high ground if 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 rainfall, there is a risk of flooding, especially in low-lying and flood-prone areas. Remember to never drive through water on the road, even if it seems shallow. According to the weather service, as little as 12 inches of rapidly flowing water can carry away most cars. Stay safe by being prepared and informed.
