PIZZA.BAT posted:Since I'm traveling down memory lane here's the goon who streamed hurricane sandy flooding his apartment protip, add enough bleach into the flood water if you ever have your place flooded to prevent any sort of mold/bacteria growth when it recedes, so it will just be some water damage and bleach smell that will dissipate over a few days when it dries out instead of being in a terrible petri dish that's extremely bad for your health source: self when some drain was clogged

Does adding enough bleach to be antiseptic not also risk doing damage to a lot of the materials you’re exposing to the bleach? Or is structural damage a given since you’re already looking at a flood, and you may as well not add uncontrolled bacterial/fungal growth to the list of problems?

I’m speculating here, but I think any organic material would handle the bleach better than the microbes. Metal objects, including electrical equipment, may fare worse with the bleach. Fungus isn’t a threat, they may be fine after cleaning and drying, but bleach will corrode them.

well you are already pretty hosed from the structural damage anyway and things that can survive flood damage might also survive the bleach like metal or plastic while it also ensures thing that doesn’t survive or whatever that was in the water will not start growing, you might be surprised at how many carbon based material can host growth to things eg books, leather, cardboard to name a few you can also replace things easier than fixing your own health when you inhale a bunch of spores and other terrible stuff

You are absolutely correct about the ACE data. However, they use a simplified version of ACE named HAX (lol) that multiplies that storm intensity level by 6-hr periods to reach a value. quote:The years 2004 and 2005 represent the first occurrence in the 157 year record of two very high hurricane activity(HAX of 601 and 618) years next to each other. Thus what is unusual in the recent hurricane activity is not high activity in an individual year, but high activity in two consecutive years. But, I was referring more to the fact that we are breaking the record of using the Greek Alphabet for storms. We have never (at least in recorded hurricane keeping) reached Eta. Also, in 2005 we hit Zeta way past hurricane seasons predicted end. we still haven't reached the close of hurricane season, and Eta is forming in the Atlantic as I type this. Sorry for any confusion.

No flooding needed, just appropriate levels of moisture working in hotels, we had a room down for like 6 months for an air conditioner that was broken and we had no replacement for. My idiot GM at the time never pressed the issue of buying replacements, just locked the door and ignored it for the entirety of an eastern North Carolina summer. 6 months later he was fired and when his temporary replacement showed up....well that one room with no climate control had become 8 rooms and instead of a $1200 PTAC, we spent nearly $10k on mold remediation.

If you ever find yourself near Neah Bay the Makah people’s cultural center is very well done and interesting. They had a story of a large mudslide that later was excavated and resulted in a ton of well preserved artifacts, including evidence of gill net fishing which was used to help establish the practice as predating the treaties to the eternal consternation of modern fisherfolk who get really pissed about natives fishing. Honestly I have no idea what the poster is talking about there were settlements and people all up and down the coast

I love the Australian native stories that have been proven through the geological record to be 10-12000+ years old, passed down word of mouth, generation to generation. What the stories of the natives of the Americas could have told and taught us we will by and large never know and that saddens me

I read a book about that a couple years ago, the edge of memory. The whole thing was absolutely fascinating. Native people in the US are doing a lot of work to preserve their histories and languages. It’s not all getting lost. I think sometimes in the US we like to act like all the native people are gone or mostly gone, but they’ve hung on and shown remarkable tenacity against outright genocide. Probably a topic for a different thread though. Back to eta watch.

In 1964, Chief Louis Nookmis, of the Huu-ay-aht First Nation, in British Columbia, told a story, passed down through seven generations, about the eradication of Vancouver Island’s Pachena Bay people. “I think it was at nighttime that the land shook,” Nookmis recalled. According to another tribal history, “They sank at once, were all drowned; not one survived.” A hundred years earlier, Billy Balch, a leader of the Makah tribe, recounted a similar story. Before his own time, he said, all the water had receded from Washington State’s Neah Bay, then suddenly poured back in, inundating the entire region. Those who survived later found canoes hanging from the trees. In a 2005 study, Ruth Ludwin, then a seismologist at the University of Washington, together with nine colleagues, collected and analyzed Native American reports of earthquakes and saltwater floods. Some of those reports contained enough information to estimate a date range for the events they described. On average, the midpoint of that range was 1701.

Kenneth Murphy, who directs fema’s Region X, the division responsible for Oregon, Washington, Idaho, and Alaska, says, “Our operating assumption is that everything west of Interstate 5 will be toast.”
