    A once-in-1,000-year rainfall event from an unnamed storm floods homes
    and forces rescues in North Carolina

    Floodwater surged into homes, stranded vehicles and forced water
    rescues in coastal North Carolina on Monday after a tropical
    storm-like system dumped historic amounts of rain in a matter of
    hours.

    "It's probably the worst flooding that any of us have seen in Carolina
    Beach," Town Manager Bruce Oakley told CNN of the tourist town not far
    from Wilmington. "We've had to rescue people from cars, also some from
    houses and businesses."

    The "in X year" metric is going to soon have no meaning; perhaps it
    already does. We've had "1 in 200 year" storms in two successive years,
    and I think the statistics break down.

    NC got 18 inches of rain. Yes, that's a lot. But not inconceivable -
    any decent hurricane (any Texans want to chime in here?) can dump that
    kind of rain. This is the future and maybe even the present.

    Makes you rethink that low-cost home built in a low spot next to a
    stream bed. Like camping next to a flash-flood gulley in the desert.
    You're inches away from death.

    Those videos of Vienna and central Czechia look really bad.

    Around here the other day, it rained some 3"...which is atypical.

    When towns were created in US, generally, they were built adjacent to
    a stream/river.

    and that was usually where trails crossed

    And....Oregon Trail River Crossings

    Written By Cody Assmann

    Crossing rivers on the Oregon Trail was one of the most dangerous
    parts of the journey.

    https://www.frontierlife.net/blog/2020/6/9/oregon-trail-river-crossings

    As you can see from the video, Oregon Trail river crossings were
    precarious events. Although Meeker's floating wagon works out good, it
    wouldn't take much more than a strong gust of wind, an unseen tree
    limb, or other upsetting to spill the wagon into the river. Still, the adventurous heart of the pioneer allowed them to overcome obstacles
    like these river crossings.
