Deciphering advisories, watches, and warnings: Understanding weather alerts
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 doesn’t guarantee that flooding will occur, but it signifies that the possibility exists.
Keeping safe during floods: Expert advice from the NWS
In flood-prone regions or while camping in low-lying areas, understanding and following the NWS flood safety guidelines can be a lifesaver:
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.
Adhere to 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 permits, disconnect your utilities and appliances. This precaution minimizes 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.
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 higher ground when trapped:
Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.
During periods of intense rainfall, the risk of flooding increases, particularly in low-lying and flood-prone areas. It is imperative to avoid driving through any water on the road, even if it seems shallow. According to the NWS, most cars can be swept away by just 12 inches of rushing water. Prioritize your safety by staying informed and prepared.
Driving through downpours: Safety guidelines for wet roads
Rain can turn roads into hazards. Stay informed and follow these tips from the NWS to ensure safety during heavy rainfall:
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:
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 stay cautious:
If it is raining and the roads are wet, slow down. Take your foot off the accelerator and let your speed drop gradually. Never use the brakes suddenly because this may cause the car to skid.
Choose your lane wisely:
Stick to the middle lanes to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.
Visibility matters:
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:
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 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.
• 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.
By following these safety measures, you can significantly reduce risks and ensure your well-being when heavy rain pours down. Stay informed about weather conditions and heed advice from local authorities to make your journey safe and sound.
