re: Beta - Downgraded to TD - Now Short Break in Storms or Season Over?

Teddy producing 42 foot significant wave height.
This is defined as the average of the highest 1/3 of the waves.
Individual waves could be over 80 feet according to NOAA if you read their explanation.

It is amazing the waves that these storms can make.
Waves from Hurricane Ivan:
quote:
When Ivan entered the Gulf of Mexico, U.S. Naval Research Laboratory ocean-floor pressure sensors detected a freak wave, which was caused by the hurricane. The wave was around 91 feet (28 m) high from peak to trough, and around 660 feet (200 m) long.[4] Their computer models also indicated that waves may have exceeded 130 feet (40 m) in the eyewall.[5]
It is damn near impossible for me to fathom waves like that.

Looks like the Euro missed again...no 10 + inches of rain from a line of storms coming from the gulf into southeast LA, no reemergence in the gulf and 2nd landfall in LA, had Laura going too far west, didnt forecast dry air coming in for storms earlier in the season... GFS has won out this hurricane season.

It's one of those things I wish it possible to safely experience

What’s the biggest wave height a vessel would be able to survive in?
Posted on 9/22/20 at 4:11 pm to NorthEndZone
Teddy is an extremely large hurricane. Hurricane-force winds extend
outward up to 125 miles (205 km) from the center and
tropical-storm-force winds extend outward up to 540 miles (870 km). Teddy is a very large system.

I have no idea, but in an article about a study on Ivan's waves I read that those type waves would likely break a ship in two.

I believe Rita had about 36ft waves.
Back then I worked for an oilfield service company, mainly Chevron. A few days after Rita passed I started calling around to see how many field hands each facility would need. I asked about Chevron Typhoon and the reply was "I don't know because they couldn't find it." It wound up drifting about 70 miles from its location, upside down of course.
Mother nature is a bitch.

Also, the platform and underwater damage from Ivan was devastating. Pipelines were moved thousands of feet and some were buried under feet of mud/sand/silt and were never found.
Ivan's Record Breaking Waves
Ivan's Record Breaking Waves
quote:
(MMS)reported that Ivan amazingly forced evacuation of 75% of the mannedplatforms in the Gulf (574 platforms) and 59% of the drilling rigs (69rigs), set adrift 5 rigs and sunk 7 rigs entirely. However, the damageby Hurricane Ivan in the oil fields in the Gulf cannot be measured byhow many platforms or rigs were destroyed. The most costly damage isbelieved to have been made to the underwater pipelines. Aside fromobvious leaks, some pipelines were reported to have moved 3000 ft whileothers were buried under 30 feet of mud and cannot be found. The mostextensive damage to the pipelines is attributed to undersea mudslides(equivalent to a snow avalanche) and to extreme waves.

That was Taylor Energy off the mouth of the Mississippi River. I think it's still leaking oil.

Depends on the vessel and circumstances. I believe some small boats survived a 100’ tsunami wave in Alaska. Something that big would probably snap a large boat in half, but a small one could ride up and over under the right circumstances. Either way regardless of the vessel I wouldn’t want to be anywhere near it. I spent a week in 15’ seas offshore and it sucked. I didn’t get sick but everyone around me was puking left and right. The whole boat smelled like barf.

Extratropical transitions can be pretty explosive over water like that. You ever wonder why Sandy had such a big deal made of it? It did this, but with a bigger and colder pool of air to mix with the tropical side. Winds aren't as high but they're fricking everywhere.

Chevron Typhoon
I remember doing inspection work on Typhoon when it was upside down. Only thing you could see of it from the surface was the base of the spar.
We followed drag marks on the sea floor from another platforms anchor lines that went right through Typhoons location. We got broken off the job before we ever found out if the other platform hit it, and caused it to beak apart, or if Rita did it.
That brings back some memories.

You ever watch the Deadliest Catch? Some of those crab boats are barely 110’. Some are a little bigger but not by much.
I can’t even imagine a boat in a 80’-100’ wave but go search Youtube for North Sea and Bering Sea videos.

They say it’s not the size of the boat but rather the motion of the ocean.
