Coastal flood advisory issued for Mobile and Baldwin counties until Monday morning

The National Weather Service issued a coastal flood advisory at 3:07 a.m. on Sunday valid from 6 p.m. until Monday 6 a.m. for Mobile and Baldwin counties.

"Minor coastal flooding expected," describes the weather service. "At 1.5 to 2.0 feet MHHW, the lowest portions of the US 90/98 Causeway at the I-10 interchange begin to observe splashover and standing water resulting in minor flooding around the eastbound I-10 on-ramps. The US 90/98 Causeway usually remains open, but brief closures of the eastbound, outside lane due to standing water and debris on the road is possible. Expect minor flooding of docks, piers, boat ramps and other low-lying areas across portions of northern Mobile Bay."

"Flooding of lots, parks, and roads with only isolated road closures expected," 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."

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.

Staying safe during a flood: Recommendations from the weather service 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 reside in a flood-prone region or are camping in low-lying terrain, the first step to safety is relocating to higher ground.

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:

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.

Refrain from walking in 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:

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. Prioritize your safety by staying informed and prepared.
