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

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

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’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.

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.

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.

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 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.

Navigating heavy rain: Essential safety measures for wet roads

When heavy rain sets in, the risk of flooding and hazardous driving conditions rises. Whether it’s prolonged rainfall or rapid runoff, being prepared is essential. Here are some valuable safety tips from the NWS to ensure you stay safe in heavy rain:

Beware of swollen waterways:

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:

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:

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

Prioritize visibility:

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

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 impairs your vision, pull over and wait for conditions to improve. Seek refuge at rest areas or sheltered 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.
