PORTLAND, Ore. (KOIN) – Although there will be another round of rain and high winds, a storm brewing in the Pacific Ocean and headed for the Oregon Coast will not be another bomb cyclone when it reaches land on Thursday night.

KOIN 6 News Meteorologist Kelley Bayern said the second storm — another midlatitude cyclone — could lead to strong winds off the coast reaching up to 30-40 mph in the valley through Friday afternoon, but will not reach the same strength as the storm that hit the coast on Tuesday.

“Models are not indicating that this next storm will undergo bombogenesis or meet the criteria to be called a bomb cyclone,” Bayern said. “It's another midlatitude cyclone and is much weaker than our recent bomb in terms of pressure. This storm will still pack a punch, though. We'll see impacts from heavy rain and high winds around the region once again.”

Oregon’s central coast will be under a severe High Wind Watch starting at 10 a.m. on Friday through the evening with south winds with the potential to blow down trees and power lines. Gusts of 60 mph winds are possible.

The back-to-back storms have become a Fujiwhara-like phenomenon, according to Meteorologist Josh Cozart. 

The National Weather Service describes the Fujiwhara effect as two equal-sized storms that “spinning in the same direction pass close enough to each other, they begin an intense dance around their common center.”

The Fujiwhara effect is more frequently used when two hurricanes “dance” around each other. However, the same effect is expected with these sub-tropical systems moving over the Pacific Ocean, though the second storm will lose its ‘bomb cyclone’ status by the time it makes landfall.
