On Wednesday at 10:56 p.m. a flash flood warning was issued by the National Weather Service in effect until Thursday at 2 a.m. for Jackson, Limestone and Madison counties.

“At 10:56 p.m., Trained weather spotters reported thunderstorms producing heavy rain across the warned area, with localized flash flooding reporting. Between 1 and 3 inches of rain have fallen. Flash flooding is ongoing or expected to begin shortly,” adds the weather service. “Flash flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as other poor drainage and low-lying areas.”

Locations impacted by the warning include Huntsville, Madison, Athens, Scottsboro, Moores Mill, Meridianville, Redstone Arsenal, Hollywood, Skyline, Gurley, Alabama A And M University, University Of Alabama In Huntsville, Harvest, Pleasant Groves, Ryland, Brownsboro, Maysville, Garth, Trenton and Hollytree.

According to the weather service, “Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles. Be especially cautious at night when it is harder to recognize the dangers of flooding. In hilly terrain there are hundreds of low water crossings which are potentially dangerous in heavy rain. Do not attempt to cross flooded roads. Find an alternate route.”

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 declared when flooding is on the verge of happening or is already underway.

• 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.

Weather service flood safety guidelines: Weathering the storm

In flood-prone regions or while camping in low-lying areas, understanding and following the weather service flood safety guidelines can be a lifesaver:

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:

• If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.

3. Disconnect utilities and appliances:

• If time allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.

4. 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.

5. 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.

6. 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.

7. Seek high ground if trapped:

• Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.

When heavy rain occurs, there is a risk of flooding, particularly in low-lying and flood-prone regions. It is important to never attempt to drive through water on the road, regardless of how deep it appears. According to the weather service, as little as 12 inches of rushing water can sweep away most vehicles. Prioritize your safety by staying informed and prepared.

Mastering wet roads: Safety tips for heavy rainfall

When heavy rain pours, the risk of flooding and treacherous roads rises. Here’s your guide from the weather service to staying safe during downpours:

Beware of rapid water flow:

• In heavy rain, refrain from parking or walking near culverts or drainage ditches, where swift-moving water can pose a grave danger.

Maintain safe driving distances:

• Adhere to the two-second rule for maintaining a safe following distance behind the vehicle in front of you. In heavy rain, allow an additional two seconds of distance to compensate for reduced traction and braking effectiveness.

Slow down and drive with care:

• On wet roads, reducing your speed is crucial. Ease off the gas pedal gradually and avoid abrupt braking to prevent skidding.

Choose your lane wisely:

• Stick to the middle lanes on multi-lane roads to minimize the risk of hydroplaning, as water tends to accumulate in outer lanes.

Visibility matters:

• Turn on your headlights and be careful of other vehicles to the rear and in blind spot areas as they are especially difficult to see through rain-spattered windows.

Watch out for slippery roads:

• The first half-hour of rain is when roads are slickest due to a mix of rain, grime, and oil. Exercise heightened caution during this period.

Keep a safe distance from large vehicles:

• Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and pass them swiftly and safely.

Mind your windshield wipers:

• Heavy rain can overload the wiper blades. When visibility is so limited that the edges of the road or other vehicles cannot be seen at a safe distance, it is time to pull over and wait for the rain to ease up. It is best to stop at rest areas or other protected areas.
• When stopping by the roadside is your only option, position your vehicle as far off the road as possible, ideally beyond guardrails. Keep your headlights on and activate emergency flashers to alert other drivers of your position.

In the face of heavy rain, these precautions can make a significant difference in ensuring your safety on the road. Remember to stay informed about weather conditions and heed guidance from local authorities for a secure journey.
