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 issued when flooding is imminent or occurring.
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.
Navigating floods: weather service flood safety guidelines for 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:
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:When local authorities issue an evacuation order, promptly comply. Before 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:Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.
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.
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.
Seek higher ground when trapped:In the event you become trapped by moving water, make your way to the highest point available and contact emergency services by calling 911.
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.
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 swollen waterways: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.
Slow down and stay cautious:On wet roads, slowing down is paramount. Gradually ease off the accelerator and avoid abrupt braking to prevent skidding.
Choose your lane wisely:Stay toward the middle lanes – water tends to pool in the outside 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: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.
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.
