#NOAA #N49RF "Gonzo" Hurricane Hunter Gulfstream jet arrived in Portland. A flight plan filed for Monday #GroundhogDay gives us a hint at the area of the Pacific they'll collect some sort of atmospheric data. https://www.flightaware.com/live/flight/N49RF/history/20260202/1915Z/KPDX/KPDX #aviation #avgeek #weather

I entered the coordinates from the #NOAA #N49RF flight plan into Great Circle Mapper and got a map of the planned flight. http://www.gcmap.com/mapui?P=KPDX-40.36+N+132.18+W-40.48+N+133.42W-40.54+N+135.12W-41.00+N+136.42W-41.00+N+138.12W-41.06+N+139.42W-41.06+N+141.12W-41.06+N+142.36W-41.06+N+144.06W-41.06+N+145.36W-41.06+N+147.06W-41.00+N+148.36W-40.54+N+150.06W-42.12+N+150.00W-43.24+N+150.00W-44.42+N+150.00W-46.00+N+149.54W-47.12+N+149.54W-48.30+N+149.48W-48.30+N+148.12W-48.30+N+146.30W-48.30+N+144.48W-48.24+N+143.06W-48.18+N+141.30W-48.12+N+139.48W-48.06+N+138.06W-47.54+N+136.30W-47.42+N+134.54W-47.30+N+133.12W-47.18+N+131.36W-KPDX #aviation #avgeek #mapgeek #weather

Though #weather will move by tomorrow's flight, #NOAA #N49RF "Gonzo" Gulfstream jet will apparently be observing two east-west cross sections from above the storm which is off the West Coast. #aviation #avgeek

No photos but I saw through binoculars from home today: NOAA49 (Hurricane Hunter "Gonzo" Gulfstream IV jet) takeoff and landing at PDX. The flight track shows they pretty much flew what they filed. But now there's a better picture of the storm front they were observing over the Pacific. https://www.flightaware.com/live/flight/NOAA49/history/20260202/1915Z/KPDX/KPDX #aviation #avgeek

#NOAA Hurricane Hunter Gulfstream IV jet "Gonzo" cancelled its Pacific flight today and stayed on the ground in Portland. It looks like the #weather nearby over the Pacific today may not have been the kind of atmospheric river conditions they wanted to collect data on. But a new flight plan showed up for Friday, again returning to Portland. This is getting to be a lengthy #science deployment. https://www.flightaware.com/live/flight/N49RF/history/20260206/1915Z/KPDX/KPDX #aviation #avgeek

A new flight plan for #NOAA Hurricane Hunter Gulfstream IV jet "Gonzo" has been filed for Wednesday, February 11, 2026, after the plane has been parked at Portland #KPDX since Friday. Now it appears they have a new #science observation target with the front that will be off the California coast tomorrow. It will then return to Portland. I used GCMap to render a map of the planned route. http://www.gcmap.com/mapui?P=KPDX-FULMR-38.18+N+133.00+W-37.24+N+134.06+W-36.30+N+135.06+W-35.36+N+136.06+W-34.42+N+137.06+W-33.48+N+138.00+W-32.54+N+139.00+W-32.00+N+139.54+W-31.30+N+138.36+W-31.00+N+137.24+W-30.30+N+136.12+W-29.54+N+135.00+W-29.24+N+133.48+W-28.48+N+132.36+W-28.18+N+131.24+W-27.42+N+130.12+W-27.06+N+129.06+W-27.42+N+128.06+W-28.12+N+127.06+W-28.42+N+126.06+W-29.18+N+125.06+W-29.48+N+124.00+W-30.18+N+123.00+W-31.18+N+123.42+W-32.24+N+124.18+W-33.24+N+125.00+W-34.24+N+125.48+W-35.30+N+126.30+W-36.30+N+127.12+W-37.30+N+128.00+W-FATMO-CITYY-TMBRS-KPDX #aviation #avgeek #weather #PNW

#NOAA Hurricane Hunter Gulfstream IV jet "Gonzo" #N49RF is making another 6+ hour flight today returning to Portland. So I have once again fed an automated translation of the flight plan waypoints into Karl Swartz's Great Circle Mapper online tool to make a map image. They have been doing winter atmospheric river observations out of Portland for 2 weeks so far. Hopefully this will collect data they want for computer forecasting models. http://www.gcmap.com/mapui?P=c:%230fff3f,KPDX-HEVOL-LATAY-SEDAR-44.42+N+131.30+W-44.23+N+133.05+W-44.12+N+134.41+W-43.53+N+136.18+W-43.36+N+137.48+W-44.00+N+139.24+W-44.23+N+141.00+W-44.47+N+142.41+W-45.12+N+144.18+W-45.30+N+146.00+W-45.47+N+147.41+W-44.42+N+147.54+W-43.42+N+148.11+W-42.36+N+148.24+W-41.30+N+148.35+W-40.23+N+148.48+W-39.23+N+149.00+W-39.06+N+147.30+W-38.42+N+145.54+W-38.23+N+144.24+W-38.00+N+142.48+W-37.36+N+141.18+W-37.12+N+139.48+W-36.47+N+138.18+W-37.42+N+137.05+W-38.30+N+135.54+W-39.17+N+134.41+W-40.06+N+133.24+W-40.53+N+132.05+W-41.36+N+130.41+W-KYLLE-ONP-LARSN-45.35+N+122.98+W-KPDX #aviation #avgeek #weather #PNW

Today's flight has been cancelled for #NOAA Hurricane Hunter jet #N49RF "Gonzo". I'm not sure if the weather didn't turn out as interesting for research or the plane wasn't ready.

There goes Gonzo! #NOAA Hurricane Hunter Gulfstream IV jet "Gonzo" #N49RF departing Portland International Airport #KPDX in the rain at noon PST today for #science observations from above the front off the coast. The data from these flights are intended to get more data from above Pacific fronts to improve computer forecasting models after a major atmospheric river event in December increased priority of studying them. #aviation #avgeek #weather #PNW

#NOAA Hurricane Hunter Gulfstream IV jet "Gonzo" #N49RF continues their deployment to Portland to collect sensor data toward improving forecasts of Pacific atmospheric river storms. The plane has been flying out of PDX a few times a week since Feb 1. Today's flight starts earlier but is shorter. It looks like they don't have to go as far out to collect storm data today with a front coming ashore.
