“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…”

"‘Hurricane Hunter’ crew spent 6 weeks at PDX, studying atmospheric rivers" by Oregon Public Broadcasting OPB (PBS Portland) - Results from #NOAA 6-week deployment to Portland #KPDX from Feb 1 to Mar 15 of Hurricane Hunter Gulfstream IV jet "Gonzo" #N49RF is already showing scientific results. New insights to structures of storms is expected to help improve forecasts of #AtmosphericRiver events. https://www.opb.org/article/2026/04/19/pdx-hurricane-hunter-crew-studying-atmospheric-rivers/ #aviation #avgeek #weather #PNW

PNW PNWing hard this week... ☔🌧️
#AtmosphericRiver #PNW

I got a picture of #NOAA Hurricane Hunter Gulfstream IV jet "Gonzo" #N49RF departing Portland Airport #KPDX at the end of what was a 6-week deployment to the Pacific Northwest to collect data on Pacific #AtmosphericRiver storms. It's now returning to its home base in Lakeland, Florida #KLAL. #aviation #avgeek #weather #PNW

...bordering the #Mediterranean, as well as two of the 4 other biggest #EU member states with populations above 60 million, does not mean, that they don't exist. I simply haven't (or don't remember) having seen them.
(I do seem to remember a similar one for #Sicilly.)

Also, and I haven't read the report in detail, it seems obvious that the #ClimateChange induced "#Monsoon- type seasons with #AtmosphericRiver-type torrential rainfalls, will be an annual phenomenon from now...

'Prolonged' ⛈️🌊 #AtmosphericRiver forecast for coastal B.C. -- starting Sunday March 15th.

⛈️ heaviest rainfall expected Monday + Tuesday
☔ up to 30cm of rain forecast for western Vancouver Island
☔ up to 12cm of rain expected for #MetroVancouver

A pretty significant tropical storm in Hawaii is "eventually going to make its way in this narrow band of, almost like a fire hose, hitting along the coast of B.C. for much of next week"

⚠️ Flooding: The accumulated snow can melt could possibly double the amount of water flowing into rivers and water bodies.

Clearly there’s a super villain in control of the weather.

New on Weather West: If we're going to see an extremely moist & warm #AtmosphericRiver this wk in NorCal that will bring rain atop recent heavy snow, why is major flooding *not* expected? It a story of (lacking) storm dynamics & snowpack resilience. #CAwx
