Portland almost closed its rainfall deficit for the year
The “bomb cyclone” that hit the Pacific Northwest over the weekend could dump three inches of rain in fire-ravaged southern Oregon forests and send foliage to Portland fall fly in the gutters.
It is also making up for lost time.
This morning, Portland is just 0.45 inches behind its standard annual precipitation through October 22, the Portland office of the National Weather Service said.
This might come as a surprise, given the heat and drought of the summer – at one point the city went on for 46 straight days without measurable rain. But a wet autumn made up the deficit.
“In fact, we could catch up with him next week,” says NWS meteorologist John Bumgardner. “We don’t plan for this, but it is possible.”
Weather systems in the Pacific Ocean over the past week – called “bomb cyclones” because air pressure drops so sharply – have drenched Oregon since Tuesday night, although Portland hasn’t been so inundated than the southwest coast of Oregon. Portland received 0.91 inches of rain on October 21 and 22, according to Bumgardner.
He doesn’t expect enough PDX rain this weekend to cause flooding. (It’s a different story on the coast, where stormy conditions could dump 4 inches in places like Brookings.) But his office issued a wind advisory, in part because Portland’s canopy is still littered with red leaves. and golden.
“If the trees still have all their leaves on them, they’re like little kites,” Bumgardner explains. “In addition, we wonder if the trees were damaged a bit by the ice storm and the heat of this summer. They might not be as strong as usual.
More good news for people who love wet news: Projections released today by the National Oceanic and Atmospheric Administration show the Portland area is receiving at least a third more rain this winter than usual.
