On Wednesday at 2:47 p.m. a coastal flood advisory was issued by the National Weather Service valid for Thursday between 8 a.m. and 2 p.m. for Mobile County.
“Minor coastal flooding expected,” describes the weather service. “Minor flooding may impact portions of Bienville Blvd on the west end of Dauphin Island and portions of Shell Belt and Coden Belt Roads.”
“Flooding of lots, parks, and roads with only isolated road closures expected. Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water,” says 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.”
Breaking down weather alerts: 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.
Weather service flood safety guidelines: 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:
1. Move to higher ground:
- 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.
2. Adhere to evacuation orders:
- When local authorities issue an evacuation order, promptly comply. Before leaving, secure your home by locking it.
3. Disconnect utilities and appliances:
- If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.
4. Avoid basements and submerged areas:
- Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.
5. Evacuate promptly for 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.
6. 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.
7. Seek higher ground when trapped:
- Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.
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 NWS, as little as 12 inches of rapidly flowing water can carry away most cars. Prioritize your safety by staying informed and prepared.
