Historic, Widespread Flooding Will Continue Through May, NOAA Says (cnn.com) 113

The U.S. is likely to see "historic, widespread flooding" through May, according to the National Oceanic and Atmospheric Association's spring outlook. From a report: "This is shaping up to be a potentially unprecedented flood season, with more than 200 million people at risk for flooding in their communities," said Ed Clark, director of NOAA's National Water Center in Tuscaloosa, Alabama. NOAA's outlook calls for nearly two-thirds of the lower 48 states to face an elevated risk of flooding through May, with the potential for major to moderate flooding in 25 states across the Great Plains, Midwest and down through the Mississippi River valley.

"The flooding this year could be worse than what we have seen in previous years ... even worse than the historic floods we saw in 1993 and 2011," said Mary Erickson, deputy director of the National Weather Service. The warning comes amid record flooding triggered by a sudden warm-up and heavy rains earlier this month brought on by the "bomb cyclone." Combined with rapid snowmelt, the factors in recent weeks have put many places in the Great Plains and Midwest underwater.

    Flooding due to early snow melting (when other water occupies the drainage basins). Higher temperatures sooner in the year causing earlier melting. What drives higher temperatures in abnormal patterns compared to records? What drives new and old water into areas different than previously used as drainage?

    These events are occurring because global warming and increased human development press on the environment at the same time. Both pressures are at fault, and have a common cause as both are driven by faster development than is supportable in the ecosystem.

      Tough break for those farmers who voted for Trump.

      First he breaks their balls with an idiotic trade war, then he diverts funding from FEMA for his wall. And of course he doesn't give a rat's ass about climate change, so that's the cherry on top.

      Where do you think much of the snowpack is, hmm...

      Maybe flooding is due to more moisture?? Like, say from a rare event that dropped a lot more moisture across a wide region than normal??

        No, you had record cold temperatures in February -- you ignore the other days mentioned in your own article:

        The cold snap came amid a wild, roller coaster swing. Denver had a high temperature of 69 degrees on Sunday, and then the temperature dropped to a low of minus 3 degrees at 6:45 a.m. Tuesday. The 72-degree swing is the 13th widest on record, spanning 147 years, in Denver in a 36- to 48-hour time range, according to the weather service.

        Similarly

        Two days, again according to your own article.

        Your February wasn't even in your top 20 coldest Februarys [weather.gov], so it's hard to see what trend carried into March.

        It may surprise you to learn that after things get cold in an area that they then get warmer which causes all that snow to melt. The increasingly extreme weather and weather fluctuations are indicative of Climate Change.

        It's not a coincidence that all these "rare weather events" are becoming increasingly common because they are part of the larger pattern that is Climate Change.

          The new weather pattern. A warmer pacific ocean is generating a new air flow pattern, with more warmer air rushing up the US West Coast and the Pacific, pushing further North than was the old pattern. This warmer air is picking up a lot of moisture as it is cooling and heating up Alaska and the Arctic accelerating ice melt and picking up that newly available water, it then has to go somewhere, so it would normally go a bit more south east but it is being blocked by a warmer Atlantic and air moving north. So it gets squeezed between the pacific air flow and the Atlantic airflow and now goes much further south pushing cold air and a whole lot of moisture, in the form of snow.

          Once that now routine weather pattern is over, warm air comes it to replace that cold air as it is pushed out over the Atlantic, and melts all the snow, really quite fast, well the further south snow, more north not so fast, so lots of flooding further south because the snow melts a whole lot faster than previous regular patterns and flooding occurs.

          Suck it up, this is the new norm, and combined with sea level rise it will really be quite bad for the US East Coast, catastrophic is no understatement. Altered water levels really screw up building footings, storm water and sewer system. You can imagine the worth of a coastline full of flooded out collapsing structures and a lot of US military bases on the east coast are on really low lying land. Then you have sea ports and airports, again on low lying land (it was cheaper) also in real trouble.

          Too late to do much about the first say 1.5m of sea level rise, maybe keep it down to 750mm but that will take real action now. The safest economic measure, simple irrigate large swathes of Australia west coast desert, pumping desalinated water inland. You obviously pull that water out of the sea, so immediate benefit but in addition, green where it was red, cools the surface of the planet at lot, then of course the new planting would absorb lots of carbon dioxide and plant transpiration cycle also cools the atmosphere and for the cheery on top, the majority of that transpiration would fall as rain on inland Australia which is lower than sea level. The more you do that and the quicker you do it, the more it will reduce the impact of climate change and it in part pays for itself with a massive social benefit, tens of thousands of square kilometres planetary food and fibre bank (trees, hemp etc). Countries could invest in desalination in resources they could directly access, especially worth while for countries with limited land area, access to thousands of sqaure kilometres of land as long as they supply the desalinate irrigation to that land.

        Our home has never flooded before and was considered completely flood proof. In fact, our entire neighborhood was considered flood proof. We're at the top of the largest hill in the are, with the river bottom portion of the city several hundred feet below us.

        We had a LONG cold streak. For more than a month temperatures were well below freezing with near unprecedented snow. Which lead to huge piles of snow along roadways and driveways. Even though the snow started as fluffy and light due to the cold, it

    • It's a damned shame that cities keep permitting people to build on flood land just because it supports their tax base. We have permitting systems in place specifically to avoid things like this, but instead we use them to keep "undesirables" out.

      • by dryeo ( 100693 )

        Funny enough, the undesirables used to be forced to live on the floodplains here. No government help back then so rich people stuck to the higher ground.

        • And now there is government help, but the help doesn't require people to relocate if they get it, and that's horribly misguided. People should either be able to stay where they are and have to do it all themselves, or get a hand up off the flood plain. I'm all for helping people, but you don't let the drowning man pull you under. You knock him the hell out if you have to.

However, when the cumulative repairs/improvements to those buildings eclipses half the value of the property, it now has to be brought within compliance with the flood zone restrictions. That is why flood zone properties are constantly being bought back and left vacant by state/county/city governments after every flood. The bigger issue wi

    Every year you put off implementing things to reduce climate change, the costs multiply many fold.

    What were once once a century storms and floods are now every 2-3 years.

    What were once massive inundations and beetle infestation wildfires are now commonplace.

    Even zoning codes have to change, to allow for redesign of buildings to survive such events every year or two, which increases building costs on average 50 percent and requires redesign of existing towns and buildings.

    Energy goes in.

    It comes out somewhere. It's like putting a bucket of bees inside. We can't tell you where the bees will sting or when, but we know there are going to be a lot of stings and consequences.

    Oh, and stop building on flood plains and lowlands and using levees. We're beyond that now. You waited too long.

    • What were once once a century storms and floods are now every 2-3 years.

      All you need is 100 independent regions and you'll have a once in a century event every year.

    • An insurance payment for a flood-damaged home should come with a relocation requirement, and replacement should not be on any other flood plain, either.

    LOS ANGELES — With California entering its fifth year of a statewide drought, Gov. Jerry Brown moved on Monday to impose permanent water conservation measures and called on water suppliers to prepare for a future made drier by climate change.

    • Aquifers can accommodate several times as much water as surface storage, but they are not refilled in a year — even a year like this one. Too much of the water runs off. Deforestation and land development tend to cause land to shed water. It runs into the ocean instead of into land which can contain it until it can seep into aquifers. Los Angeles is the American poster child for this; it's got so much pavement that basically all of the water runs off immediately. I've read that they get enough rainfal

    I lived near the Missouri river in mid Missouri, from birth to 20. When you travel around the capital area of Jefferson City, you see "the river bluffs". The Missouri river, as most rivers, have been SQUEEZED and SQUEEZED over the centuries, to claim the rich soil used to grow crops. When you have a major event, the river wants to go where it was, not where man "thinks" it should be.

    Sooo they are going to ignore the dam break that was from bad construction that caused Iowa's flooding?? Am I also supposed to ignore all the early thaws or quick thaws of my childhood in the 70's?? If you are going to tell me some bullshit at least have it account for things that happened in the past and when facts come out about failed dams that the US Army Corp. built. That way you don't look as full of shit as you do now.
