A new @UNC study quantifies $562M in financial risk from Hurricane Florence using a novel modeling approach that evaluates risk of mortgage default and property abandonment.

@ReedTimmerAccu Not trying to call you out but want to share this to improve the terms used for this area. https://t.co/CYdm9AJnEN

Risk from responses to climate change.

We discuss managed retreat and solar geoengineering to elaborate the importance of understanding response as a determinant of climate change risk.

Here is our 3-category ENSO-based probabilistic MAM severe convective storm activity forecast using the DJF ONI (released today) of -0.7. Methodology by @lapiccolaflo and @JTAllen3 in https://t.co/h8Z5FN5TCY

#Ida's intensification continues with peak winds near 150 mph. Storm is more compact than Katrina with less than half the Integrated kinetic energy 45 TJ compared to > 100 for Katrina. Analysis based on measurements from @NOAA_HurrHunter, @53rdWRS, @TTUHRT and @UFwind.

@KellyHereid Really enjoyed it! You said it perfectly that flood is a peril that is showing insurance companies where their data bodies are buried! So true that bad data doesn’t fly when you are modeling high gradient perils, especially when assessing impacts of climate change!

[Moody's HWind @hwind]

#HurricaneDelta now near 105 mph. Delta has grown significantly from an 8 mile Rmax and minimal 14 TJ of IKE just before landfall near Cancun to a 20 mile Rmax and 35 TJ of IKE now based on measurements from @NOAA_HurrHunter and @53rdWRS.

#HurricaneSally's wind field getting stronger and better organized. Max winds near 90 mph now much closer to center based on measurements from @NOAA and @53rdWRS hurricane hunter aircraft.

Evolution of today's damaging derecho, from a cluster of thunderstorms in South Dakota to its passage through Chicago, overlapped with Storm Prediction Center damaging wind reports:

At 1800 UTC, recon measurements from @noaa and @53rdWRS indicate that #HurricaneIsaias has weakened further battling shear and dry air. Isaias still has plenty of warm deep water ahead of it to support gathering steam again. https://t.co/YpGI5cQMkz

Stormy afternoon Oklahoma.

Quite a few ⚡️ flashes.

@StephenMStrader @scatterazure @burgwx Thanks! I’ll be sure to check them out ;)

It's been a while since I've done this type of analysis, but looking at COVID-19 cases by county population density, the largest increase is occurring in counties with small population density. Urban counties are seeing a slight increase again, likely due to Los Angeles.

[Holly Widen @hmwiden]

@StephenMStrader @scatterazure Nice maps! Would be interesting to add in or highlight areas that are more relaxed with reopening.

@SJChilds01 @CSUAtmosSci @russ_schumacher I bet that had to be weird! Will be a good story down the road. Congrats Dr. Childs!! 🎉

Here is an example of a counterfactual analysis we did back in 2017 of the Oroville Dam near-miss... https://t.co/ZNJ5aDeEoi

This issue of aging flood control infrastructure makes conducting counterfactual risk analyses that much more important #DamFailure #RMS #counterfactual

[Bob Henson @bhensonweather]

The just-failed #Sanford and #Edenville dams--both 95 years old and privately owned--are both rated "high hazard" in the National Inventory of Dams. (https://t.co/xx7Y55SGAQ) High hazard = "loss of human life is likely if a dam were to fail."
