The Pacific Northwest is once again reminded of its infamous rainy season as Portland, OR, dives headfirst into a downpour that has prompted the National Weather Service (NWS) to issue a range of weather warnings. The NWS details a "Flood Watch" expanding across several counties in both Oregon and Washington through Thursday afternoon due to persistent rains that have saturated the region.
From the crests of the north Oregon Cascades to the coastal lowlands, the tempest has not discriminated in its reach. Over the past 24 hours, accumulations have ranged from a daunting 4 to 7 inches over mountainous terrains to a substantial but lesser 1.5 to 4.5 inches over urban landscapes such as the greater Portland/Vancouver metro. The deluge is set to persist with an additional 1 to 2 inches expected, bringing with it an “elevated threat for urban and river flooding”, as stated by the NWS. Furthermore, the advisory warns of potential landslides and debris flows in steep slopes, particularly near canyons, where the earth is now vulnerable.
Johnson Creek, at Sycamore, has not been spared, currently under a Flood Warning with the creek levels forecasted to oscillate around the flood stage. The warning emphasizes the serious risk flooding poses, illustrating "above 11.0 feet, minor flooding begins along Johnson Creek between SE 92nd Street to SE 122nd Street and between Johnson Creek and SE Harold Street." Initial reports at 3:30 AM PST Tuesday placed the creek's stage at 7.7 feet, just shy of the bankfull stage of 10.0 feet, beckoning residents to remain vigilant.
An accompanying "Flood Advisory" remains in effect for the Multnomah and Washington counties in Oregon, and Clark County, Washington, until 10 AM PST today. The weather lashings have led to "urban and small stream flooding," with major thoroughfares covered in water and minor flooding in low-lying areas. Due to the already 1.5 to 2.5 inches of rainfall combined with an expected additional 0.5 to 1 inch, residents are advised to heed caution and anticipate continued disruptions. The advisory implores for awareness, "Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles."
As the region navigates through the relentless rainfall, the NWS remains the primary source for up-to-the-minute updates and safety guidelines. They urge locals to monitor forecasts and prepare to act should more severe flooding develop. The reality of the season's wrath plays out in real-time, with the ever-present hum of rain serving as both a familiar backdrop and a potent reminder of nature's untamable force.
