A flood watch was issued by the National Weather Service on Saturday at 11:03 a.m. valid from Sunday 4 a.m. until Wednesday 4 a.m. for Clatsop County Coast, Tillamook County Coast, Central Coast of Oregon, North Oregon Coast Range Lowlands, Central Oregon Coast Range Lowlands, North Oregon Coast Range, Central Oregon Coast Range, Lower Columbia River, Tualatin Valley, West Hills and Chehalem Mountains, Inner Portland Metro, East Portland Metro, Outer Southeast Portland Metro, West Central Willamette Valley, East Central Willamette Valley, Benton County Lowlands, Linn County Lowlands, Lane County Lowlands, West Columbia River Gorge of Oregon above 500 ft, West Columbia River Gorge I-84 Corridor, Upper Hood River Valley, Central Columbia River Gorge I-84 Corridor, Clackamas County Cascade Foothills, Cascade Foothills of Marion and Linn counties, Lane County Cascade Foothills, North Oregon Cascades, Cascades of Marion and Linn counties and Cascades of Lane County.

The weather service comments, "Flooding caused by excessive rainfall is possible."

"Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations, especially for rivers draining the Willapa Hills and Oregon Coast Range. Flooding may occur in poor drainage and urban areas. Landslides are possible through this period, especially over the Cascades due to heavy rainfall above 7,000 feet combined with snowmelt. There is low probability for debris flows as rainfall rates are not expected to meet thresholds over recently burned areas," describes the weather service. "You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop."

Deciphering advisories, watches, and warnings: Understanding weather alerts

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.

A flood warning is issued when flooding is imminent or occurring.

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.

A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.

Weathering the storm: Flood safety guidelines from the weather service

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.

If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.

If time allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.

Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.

If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity.

Never attempt to walk through floodwaters, even if they appear shallow. Just 6 inches of fast-moving water can forcefully sweep you off your feet.

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 weather service, most cars can be swept away by just 12 inches of rushing water. Prioritize your safety by staying informed and prepared.

Navigating rainy roads: Safety tips for wet weather

In heavy rain, refrain from parking or walking near culverts or drainage ditches, where swift-moving water can pose a grave danger.

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.

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.

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

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.

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.

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