atmospheric river events\u2019 expected next week, significantly flooding rivers \u2013 KIRO 7 News Seattle"},"content":{"rendered":"<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">While Friday through the weekend will be wet and breezy at times, significant concern continues over the weather situation next week with the likelihood of several atmospheric river events bringing significant flooding on our area rivers. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Also, we\u2019ll be facing an increased landslide risk even in the lowlands. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">New forecast data are trending toward an onset of heavier rain on Monday afternoon, lasting into Tuesday. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">There could be a brief break before more very heavy rain Tuesday night through at least Wednesday.<\/p>\n<p>THIS WEEKEND<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Upwards of an inch of rain in the lowlands will fall through Sunday with 2-5 inches in mountain locations. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">There will be a time of snow at higher mountain locations even down to Stevens Pass late Friday through Saturday before snow levels rise again. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">The rainfall will work to cause area rivers to rise, but significant flooding is not expected this weekend.<\/p>\n<p>LOWLANDS NEXT WEEK<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">From Monday through Wednesday, we expect an average of 2-6 inches of rain to fall in the lowlands of Western Washington, with the higher of these amounts mainly south of Puget Sound. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">The least amounts will fall across areas north of Everett and the northeast Olympic Peninsula. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Rainfall amounts of this magnitude will cause some urban flooding where storm drains get clogged or overwhelmed. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">The risk of shallow landslides will rise next week as well. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Shallow-rooted trees could fall when soils become completely saturated.<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">If current projections hold, this could be our heaviest lowland rainfall event areawide since at least early 2022.<\/p>\n<p>RIVER FLOODING<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Extreme rainfall is expected for our mountains, starting Monday afternoon lasting through at least Wednesday. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Rainfall totals of 5-11 inches will be common in the mountains, with some forecasts pointing to even higher amounts in a few of the favored spots. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Snow levels near or above 6,000 feet means snow will fall only on the higher slopes and volcanoes. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Much of the precipitation that hits our mountains will run off into rivers.<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">People living near rivers or river floodplains need to review their preparedness now for significant flooding. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">As of Friday afternoon, the Snoqualmie River at Carnation is forecast to rise quickly Tuesday to near major flood stage by Tuesday evening, with another crest near or slightly above major flood stage on Thursday. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">If those levels are reached, it would be the worst flooding on the Snoqualmie River since March of 2022.<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">The Snohomish River near Monroe is also expected to near or reach major flood stage on Tuesday evening and again on Thursday, with the worst flooding since 2020. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">These river forecasts are highly variable and subject to change based on rainfall trends.<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">The Skagit, Skykomish, Snohomish, and Cowlitz rivers are forecast to each moderate flood stage with the highest water levels from Tuesday through Thursday. <\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Other rivers and streams will run high or experience minor flooding, as current forecasts indicate.<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">It is possible the flooding risk will extend beyond next Thursday on many river systems and the landslide risk will continue for a while even after heavy rainfall ends.<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph\">Stay with KIRO 7 News through the weekend and into next week for the latest updated forecast information and live coverage of this developing flooding and heavy rainfall event.<\/p>\n<p class=\"default__StyledText-sc-tl066j-0 gdrPeS body-paragraph
