Flood maps drive real decisions, but optical imagery is cloudy when floods hit. Our new guide shows how to train a cloud-aware #UNet in #PyTorch on #Sentinel2 data, evaluate with #IoU and Dice, and export #GIS layers for #DisasterRisk work.

Flood Risk Mapping with Sentinel‑2 in Python (U‑Net)

Build a cloud‑aware U‑Net in Python to segment flood extent from Sentinel‑2, evaluate with IoU/Dice, and export GIS‑ready risk layers for response planning.

High winds and heavy rain can bring down tree limbs or whole trees. This was the case last night near a Southern California Edison (SCE) substation, leading to an unplanned outage affecting about 15,000 Conejo Valley customers, with many losing grid power for an hour or more. Here is SCE’s report:

“On February 10 at 2055 hours, a 30-second electrical disruption affecting approximately 15,000 customers in Agoura Hills, Thousand Oaks, and Westlake Village occurred when eleven 16kV circuits out of Potrero Substation relayed and reclosed. At 2132 hours, a portion of the substation was interrupted. Preliminary reports indicate tree branches contacted substation equipment. Most customers were restored at 2254 hours and all power was restored at 2310 hours. There were no reported injuries.”

Another storm is headed our way next week, with rain forecast Sunday through Thursday. SCE has tips on emergency preparedness here: https://www.sce.com/outages-safety/outage-preparedness/outage-tips/emergency-preparedness-kit

In the United States, the monopoly utility operates under a perverse incentive structure most people never see because it lives in rate cases, spreadsheets, and footnotes. It has a polite name—Rate-of-Return Regulation—but the logic is brutal:

They are allowed to earn a guaranteed return on new infrastructure.

They earn essentially nothing on maintaining old infrastructure.
