At 5:08 p.m. on Wednesday, the National Weather Service issued a flood advisory in effect until 8:15 p.m. for Arapahoe and Douglas counties.
The NWS informs, “Urban area and small stream flooding caused by excessive rainfall is expected.”
“Minor flooding in low-lying and poor drainage areas. Ponding of water in urban or other areas is occurring or is imminent,” states the NWS. “Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles. Excessive runoff from heavy rainfall will cause minor flooding of small creeks and streams, highways, streets, underpasses, drainage areas and other low lying spots.”
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 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 does not mean flooding will occur, but it is possible.
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 reside in a flood-prone region or are camping in low-lying terrain, the first step to safety is relocating to higher ground.
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.
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 sounds, evacuate without delay. Do not enter water that may carry an electrical charge.
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 higher ground when 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 NWS, as little as 12 inches of rushing water can sweep away most vehicles. Prioritize your safety by staying informed and prepared.
Navigating rainy roads: Safety tips for wet weather
When heavy rain strikes, safety is paramount. Equip yourself with these guidelines from the NWS to navigate wet roads and avoid hazards:
Beware of rapid water flow:
Avoid parking or walking in close proximity to culverts or drainage ditches, as the swiftly moving water during heavy rain can potentially carry you away.
Maintain safe driving distances:
The two-second rule for following distance is your ally in heavy rain. Extend it to four seconds to ensure safe spacing in adverse conditions.
Slow down and drive with care:
On wet roads, reducing your speed is crucial. Ease off the accelerator gradually and avoid abrupt braking to prevent skidding.
Choose your lane wisely:
Stay toward the middle lanes – water tends to pool in the outside lanes.
Prioritize visibility:
Enhance your visibility in heavy rain by turning on your headlights. Watch out for vehicles in blind spots, as rain-smeared windows can obscure them.
Watch out for slippery roads:
Be extra careful during the first half hour after rain begins. Grime and oil on the road surface mix with water to make the road slippery.
Keep a safe distance from large vehicles:
Don’t follow large trucks or buses too closely. The spray created by their large tires reduces your vision. Take care when passing them as well; if you must pass, do so with caution.
Mind your windshield wipers:
• Overloaded wiper blades can hinder visibility. If rain severely limits your sight, pull over and wait for conditions to improve. Seek refuge at rest areas or protected spots.
• If the roadside is your only option, pull off as far as possible, preferably past the end of a guard rail, and wait until the storm passes. Keep your headlights on and turn on 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.
