    “At the Canadian Water Resources Association National Conference in Winnipeg, colleagues shared insights from Canada's Flood Hazard Identification and Mapping Program. This initiative has seen over 400 flood mapping projects and more than 1,000 flood hazard maps produced, supported by a substantial investment of $164.2 million from 2024 to 2028.
    Two key datasets:
    • The Canada Flood Map Inventory, which records the locations of flood hazard maps and provides information on how to access them.
    • The national Flood Susceptibility Index, a machine-learning assessment of flood-prone areas, including regions that have not been mapped in detail.
    When these two layers are combined on a single screen, it becomes clear where future mapping efforts should be directed — specifically, areas with high susceptibility that currently lack detailed maps…”

    #Mudslides, 126-mph winds and feet of snow pummel #California amid #AtmosphericRiver

    The biggest storm so far this winter blasted California with #flooding #downpours, #hurricane-force winds and feet of #snow in the mountains. Some of the worst damage occurred near the #BurnScars from January's deadly #fires.

    By Brian Lada, AccuWeather meteorologist and senior content editor

    Published Feb 14, 2025

    "Mudslides, flooding downpours and feet of mountain snow were unleashed across California as the biggest storm so far this winter hit the state, including areas devastated by deadly #wildfires in January.

    "Evacuations were ordered and roads were shut down near the burn scars of the #PalisadesFire and the #EatonFire due to the risk of mudslides, flash flooding and debris flows, including a stretch of the #PacificCoastHighway between #Malibu and #SantaMonica.

    "A person with the Los Angeles Fire Department was swept away in a vehicle amid the flooding but managed to escape with only minor injuries, according to The Associated Press.

    "Bulldozers were needed to clear feet of mud, rock and debris from some roads as the heavy rain ran off the charred mountainsides.

    "'Over 10 inches of rain fell in some areas, including 10.87 at Manchester, on the coast west of #Sacramento, and 9.89 inches at Mining Ridge, 90 miles south of #SanJose,' AccuWeather Meteorologist and Digital Producer Jesse Ferrell said.

    "Rain even fell in California's #DeathValley National Park, with 0.18 of an inch falling in the hottest place in North America. In an entire year, the remote park typically measures 2.20 inches of rain."

    random thought about Permian and Triassic climates: To me, the huge ocean Panthalassa seems like a good recipe for huge atmospheric rivers: it was huge, it had lots and lots of warm water, and in warm climate the air could take up a huge amount of water. (This is how I imagine the Carnian pluvials, for example.)

    An article about modern atmospheric rivers, for reference:

    In the rubric of #ClimateChangeIsTheLastStraw

    #TulareLake was the largest lake west of the Mississippi.
    You would think a #water reservoir in an arid state is something to protect.
    But no.
    People drained it, to grow thirsty crops like #almonds, plus #dairy cattle.

    This winter, #California got hit by more than one #AtmosphericRiver; the #snow pack is deep. That's now melting.
    The meltwater is refilling the lake. And the warm season hasn't even started yet.

    Atmospheric Rivers FTW, now just need water management to survive and thrive
