Deciphering advisories, watches, and warnings: Understanding weather alerts

• 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 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.

Weathering the storm: Flood safety guidelines 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:

1. 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.

2. Follow evacuation orders:

• When local authorities issue an evacuation order, promptly comply. Before leaving, secure your home by locking it.

3. Disconnect utilities and appliances:

• If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.

4. Steer clear of flooded basem*nts and submerged areas:

• Steer clear of basem*nts or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.

5. 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.

6. Refrain from walking in floodwaters:

• Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.

7. 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.

Driving through downpours: Safety guidelines for wet roads

Heavy rainfall may lead to flooding if prolonged or if there is excessive runoff. Excessive runoff can be a result of saturated ground and/or rainfall intensity. Follow these recommendations from the weather service to stay safe in heavy rain:

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:

• Use the two-second rule to maintain a safe distance from the car in front of you and allow an extra two seconds in heavy rain.

Reduce speed and drive cautiously:

• 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:

• Stay toward the middle lanes - water tends to pool in the outside lanes.

Visibility matters:

• Enhance your visibility in heavy rain by activating your headlights. Be particularly vigilant 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:

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

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.

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.
