The killer app for hurricane prediction? It could be drones that explore hurricanes and send back real-time data — or new satellite tech that gives forecasters a better look at storms from above, Jennifer A. Kingson and Andrew Freedman report. Why it matters: Accurate forecasts will be increasingly vital as climate change makes for more intense and wetter hurricanes, which undergo rapid intensification. Where it stands: Today's monitoring systems are good at predicting a storm's track but struggle to anticipate intensity changes. - To improve predictions, scientists need more information about hurricanes' relatively small core. Right now, those are mainly sampled by human-flown Hurricane Hunter aircraft.
What's happening: In recent firsts, uncrewed airborne and seaborne drones have transmitted live data and video from inside these violent storms, including areas off limits to Hurricane Hunters. - The drones complement advanced satellites (including a planned private-sector network) and a new hurricane forecasting model the National Oceanic and Atmospheric Administration (NOAA) aims to adopt next year.
Driving the news: After enduring an especially rough ride into Hurricane Ian, NOAA scientists deployed a 27-pound drone called Altius into the storm's eye and eyewall, where it spent two hours "acquiring critical measurements to understand these complex storm systems," the agency says. - The 8-foot drone was released from "Kermit," one of NOAA's Hurricane Hunter aircraft.
- It was able to communicate from an impressive range of 100 miles, keeping Kermit's human pilots out of harm's way.
- Last year, NOAA first used "Saildrones" — surface vessels that troll the ocean to assess storm intensity.

NOAA has been testing drones for years, but the latest generation is more sophisticated, providing real-time views of a hurricane's shifting track and intensity. - "They're so new," Frank Marks, director of NOAA's Hurricane Research Division, said of the drones. "We haven't really taken advantage of them beyond seeing things we've never seen before."
- Going forward, the "kind of technology combination we're looking for is the manned aircraft flying the safer part of the storm a little higher" while drones dive into the eye.
The big picture: For storm intensity forecasts in particular, NOAA has been developing a new and improved system known as HAFS — the Hurricane Analysis and Forecast System — and hopes to implement it next spring. - Marks says he was "blown away" with how HAFS performed during real-time experiments on Hurricanes Ian and Fiona.
Meanwhile, Boston-based weather and climate intelligence firm Tomorrow.io is building a constellation of 12 satellite-mounted radars meant to scan developing tropical storms and hurricanes hour by hour. The bottom line: Not only can these new technologies pump out data that improves forecasting models, the drones can also beam video that conveys the ferocity of the storm to the general public — potentially persuading people to evacuate.
