The National Weather Service has issued a Wind Advisory for the entire northwest, due to an impressive “Bomb Cyclone” off the coast, effective from 2 p.m. Tuesday, Nov. 19 through 4 a.m. Wednesday, Nov. 20, 2024.
Residents are advised to batten down the hatches for east to southeast winds ranging from 20 to 30 mph, with gusts reaching up to 50 mph.
The advisory warns that gusty winds could blow around unsecured objects like patio furniture, bring down tree limbs, and potentially cause localized power outages.
The strongest winds are expected Tuesday evening into early Wednesday morning.
Meteorologists noted that significant impacts may occur even at lower-than-usual wind speeds due to the atypical easterly wind direction.
Residents are urged to secure outdoor items and exercise caution while driving, particularly if operating high-profile vehicles. The National Weather Service advises using extra care in areas prone to wind-related hazards.
“An anomalously strong surface low will continue to intensify offshore on Tuesday, bringing significant weather to western Washington,” forecasters said.
The term “bomb cyclone” may sound dramatic, but it originates from the meteorological term “bombogenesis.” This phenomenon refers to a rapidly intensifying storm system that strengthens significantly by dropping at least 24 millibars in atmospheric pressure within a 24-hour period.
The following impacts are listed below:
- STRONG WINDS: Intense pressure gradients will cause strong east winds to develop Tuesday afternoon through Wednesday morning. Areas along the Pacific Coast and along the Cascade Foothills will see gusts up to 65 mph. Areas elsewhere will see gusts up to 50 mph. Most area waters are favored to see Storm Force winds. The strongest winds will occur Tuesday evening into the early morning hours Wednesday. Significant impacts may occur at lower-than-usual wind speeds due to the atypical easterly wind direction.
- BLIZZARD CONDITIONS: Strong winds in combination with moderate mountain snow will impact travel through the Cascade Passes, where gusty winds will likely cause periods of whiteout conditions. The strongest impacts will occur Tuesday evening through early Wednesday morning when east winds will be strongest.
A King Tide Too!
Oh, and did we mention that there will also be a King Tide during this weather event? It’s due to hit on Tuesday, Nov. 19 at 8:16 a.m., with a +12.4 tide.
So if you’ve got waterfront property, consider starting your morning early with a sturdy pole to help clear those big pieces of driftwood that will surely be slamming into your bulkhead. Oh, and be sure to take photos/videos and share with us via email to scott@southkingmedia.com.
