At 4:27 a.m. Wednesday, the National Weather Service issued an updated flood watch in effect until 8 p.m. Friday for the South Central Oregon Coast, Curry County Coast, Eastern Curry County and Josephine County, and the Siskiyou Mountains and Southern Oregon Cascades.

The weather service says, “Flooding is possible from continued heavy rainfall.”

“Excessive runoff can lead to flooding of rivers and streams and low-lying or flood-prone areas. Flooding can also occur in areas of poor drainage and in urban areas, as storm drains and ditches can become clogged with leaves and other debris. There will be an increased risk of rock falls and landslides on steep slopes and road cuts,” explains the weather service. “You should monitor further forecasts and be alert for possible flood warnings. Those living in flood-prone areas should be prepared to take action if flooding develops.”

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 areas prone to flooding, it is essential to move to higher ground immediately. A flash flood is a sudden and violent flood that can develop within minutes to hours and can happen even 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 of:

A flood advisory is issued when flooding is not expected to be severe enough to issue a warning. However, it can cause significant inconvenience and, if care is not exercised, can lead to life and/or property-threatening situations.

• Flood Watch: Be Prepared:

A flood watch is issued when conditions are favorable for flooding. It does not guarantee that flooding will occur, but it does mean that there is a possibility.

Riding out the storm: Flood safety instructions from the weather service

In flood-prone regions or while camping in low-lying areas, understanding and following the weather service’s flood safety guidelines can be a lifesaver:

Seek higher ground:

If you are in a flood-prone area or camping in a low-lying area, move to higher ground as a first step.

Follow evacuation orders:

If local authorities issue an evacuation order, heed them promptly. Before you leave, secure your home by locking it.

Disconnect utilities and appliances:

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

Avoid flooded basements and submerged areas:

Avoid basements or rooms submerged in water with electrical outlets or cables. Preventing electrical accidents is essential.

Evacuate promptly for safety:

If you see sparks or hear buzzing, crackling, popping or noises, evacuate immediately. Avoid any water that may be electrically charged.

Refrain from walking in flood waters:

Never attempt to wade through flood waters. Even just 6 inches of fast moving water can knock you off your feet.

Seek higher ground when trapped:

If you become trapped in moving water, get to the highest point possible and call 911 to contact emergency services.

During periods of heavy rainfall, the risk of flooding increases, especially in low-lying and flood-prone areas. It is imperative to avoid driving through any water on the road, even if it appears shallow. According to the weather service, most cars can be swept away by as little as 12 inches of flowing water. Stay safe by being prepared and informed.

Driving in showers: safety instructions for wet roads

When it rains heavily, safety is paramount. Equip yourself with these guidelines from the weather service to navigate wet roads and avoid hazards:

Beware of fast flowing water:

Avoid parking or walking in close proximity to drains or ditches, as fast-moving water during heavy rains can wash you away.

Keep driving distances safe:

Follow the two second rule to maintain a safe following distance behind the vehicle in front of you. In heavy rain, allow an extra two seconds of gap to compensate for reduced traction and braking efficiency.

Reduce speed and drive carefully:

On wet roads, slowing down is paramount. Release the throttle gradually and avoid sudden braking to prevent skidding.

Choose your lane wisely:

Stay in the middle lanes to minimize the risk of hydroplaning. The outer bands are more prone to water accumulation.

Visibility matters:

Improve your visibility in heavy rain by activating your headlights. Be especially alert to vehicles in your blind spots, as rain-soaked windows can hide them.

Beware of slippery roads:

The first half hour of rain is when the roads are more slippery due to the mixture of rain, dirt and oil. You have increased attention during this period.

Keep a safe distance from large vehicles:

Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and get through them quickly and safely.

Attention to the windshield wipers:

• Overloaded wiper blades can impede visibility. If the rain is seriously affecting your vision, stop and wait for the conditions to improve. Seek refuge in rest areas or sheltered places.
• If the side of the road is your only option, pull over as far as possible, preferably over the end of a guardrail, and wait for the storm to pass. Keep your headlights on and turn on your hazard lights to alert other drivers of your position.

In the face of heavy rain, these precautions can make a big difference in keeping you safe on the road. Remember to be informed about the weather conditions and take into account the guidance of the local authorities for a safe journey.
