    60 minutes did a great story on the flood protection systems across the Netherlands last night. They showed the amazing job that the Dutch did with the dunes at Katwijk.

    Nice. Makes me miss that place. Havent been over there in 9 years, seems like forever. Truly a special country with great people.

    This is how you build a protective dune.

     

     

    That's awesome. My family is from Holland, and our ancestoral hometown is Nordwijk, the next town north from Katwijk. Some of the artificial dunes up in that area are massive, and resemble natural rolling hills. That area had massive flooding in the 1950s and since then the Dutch have engineered amazing flood protection systems.

    Areas affected...SE NY...Long Island...Southern New England
    
    Concerning...Heavy rainfall...Flash flooding possible
    
    Valid 121921Z - 130000Z
    
    Summary...Showers and thunderstorms with rainfall rates up to
    2"/hr will continue along a stationary front this afternoon. Flash
    flooding is possible.
    
    Discussion...GOES-16 visible imagery shows a clear demarcation of
    clear sky conditions along and south of a surface boundary draped
    along the coast from near Philadelphia, PA northeast towards
    Chatham, MA. Within this clear area, MLCape has risen to 500-1000
    J/kg which has allowed thunderstorms to develop and persist across
    the threat area. PWATs across the region are over 2 inches, and
    latest 18Z upper air soundings from KOKX have freezing levels
    nearing 15 kft, above the 90th percentile for the date. This deep
    warm cloud depth and high PWAT is allowing efficient rain
    processes, with rainfall rates over 2"/hr estimated recently by
    KOKX radar.
    
    Although instability weakens north of the front, warm advection
    atop the boundary is driving lift, aided by weak PVA and
    diffluence within a 300mb jet entrance region. 18Z soundings from
    CHH and OKX have 20kts of 0-6km shear, so multicell development is
    possible, which could train thanks to boundary parallel flow and
    corfidi vectors aligned with the 0-6km mean wind.
    
    The high res guidance is varied in continuing or intensifying
    convection through the remainder of the afternoon, but the
    sufficient lift in a very moist environment supports at least a
    continuation of a heavy rain threat through this evening. Many
    places within the threat area have received 2-4" of rainfall in
    the past 24 hours, and these antecedent conditions lead to an
    enhanced flash flood threat. An additional 1 to as much as 3
    inches of rainfall is possible, and flash flooding will be
    possible where rain rates become 2"/hr.
