[Science News] Between 2021 and 2023, a rise in #ocean temperatures in the tropical zone (between the western Pacific and the eastern Indian Ocean) led to increased #snowfall in #Antarctica and, consequently, an increase in the mass of the #ice sheet.

“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…”

Interactive map with a dark grey line showing the perimeter of the area burned early this year by the #PalisadesFire. The yellow/gold/red colors show drainage basins with a low/moderate/high risk of debris flow if there is lots of rain in a fairly short time period. The black dots mark the outlets of drainage areas.

You can drag the map over to the area burned by the #EatonFire

Info on #DebrisFlow cameras. Snipped from FB. #AtmosphericRiver #CAwx

"Update: all seven new cameras are now online
With a major atmospheric river projected to hit Southern California this week, ALERTCalifornia's field team has been working hard to install seven new cameras around Los Angeles to help emergency managers monitor potential debris flows from the Eaton and Palisades burn scars. The Bailey Canyon 1 & 2, Sierra Madre Canyon 1 & 2, and Sierra Madre Bridge cameras are already online for the the Eaton Fire scar. Cloudcroft 1 & 2 cameras will be online soon for the Palisades Fire scar. Search camera names at cameras.alertcalifornia.org to see their locations."

I was wondering when the #NortheasternUS would get hit with a #BombCyclone... Ugh!

Developing 'bomb cyclone' with #AtmosphericRiver to blast eastern US

By Alex Sosnowski, AccuWeather senior meteorologist
Published Dec 10, 2024

"A rapidly strengthening storm packed with a firehose of moisture will swing across the eastern United States through Wednesday night with areas of flooding rainfall, damaging winds and major travel disruptions."

...houses this way...
All this passive cooling instead of using A/C would have a huge impact on energy usage.

I reckon that if we could capture and store the #AtmosphericRiver and #Flashflood/#Monsoon-type #rainfalls regionally, that would also be a huge game-changer.
