- Current administration's destruction of NCAR will be an unmitigated disaster that will kill lots of people. When they destroy something that saves lives, that's what they're doing. They won't move important parts somewhere else. Entire point is destruction & mayhem like every other action they take.
- The Air Force & NOAA hurricane hunters conducted 33 missions into, and around, #Melissa. Additional information appears in the alternate text for the images.

We’re working with local partners to serve meals as quickly as possible. Read more: wck.org/news/hurricane-melissa #ChefsForJamaica

- Reposted by Tropical AtlanticA climate justice disaster is underway in Jamaica as Hurricane Melissa moves over the island.
- Reposted by Tropical AtlanticMajor Hurricane Melissa makes a historic landfall near New Hope, Jamaica.
- 1:00pm EDT on Oct 28, 2025: #Melissa has made landfall near New Hope, Jamaica with 185mph wind & pressure of 892mb. For wind, ties for strongest landfalling Atlantic hurricane matching Labor Day hurricane in 1935 in Florida Keys & Dorian in 2019 in Bahamas. For pressure, ties for Labor Day hurricane
- At 11:15 am EDT, Air Force hurricane hunters posted about returning to Curacao "after encountering heavy turbulence today while entering the eye of Hurricane Melissa". "During the event, the aircraft briefly experienced forces stronger than normal due to turbulence" www.facebook.com/hurricanehun...
- A catastrophic, historical event is about to unfold in Jamaica. Hurricane warnings are also in effect for parts of eastern Cuba and parts of the Bahamas which will also experience the impact of #Melissa.
- 9:05am EDT Monday on #Melissa: Air Force dropsonde has measured a pressure of 893 millibars. (with 13 knots of surface wind this may indicate a pressure of around 892 millibars) If 893mb, it makes it 4th strongest ever recoded in the Atlantic in terms of pressure. If 892mb, it makes it tied for 3rd.
- If #Melissa makes landfall with a pressure of 892 millibars, it would tie as the lowest pressure on record for a landfalling Atlantic hurricane. The "1935 Labor Day" hurricane in 1935 made landfall in the Florida Keys with a pressure of 892mb.
- 9am EDT Tuesday update from NHC on #Melissa: "An Air Force Reserve Hurricane Hunter aircraft has found that Melissa is strengthening with maximum sustained winds of 180 mph (290 km/h). Estimated minimum central pressure based on aircraft data has fallen to 896 mb (26.47 inches)." www.nhc.noaa.gov
- Air Force hurricane hunters departed at 6:12am EDT from Curacao for #Melissa.
- In regard to high SFMR readings with the current Air Force mission, please see this post from @franklinjamesl.bsky.social. SFMR readings are estimated. Recon does indicate that Melissa is further strengthening and some of the most recent flight level wind data was not available for the 2am advisory.
- A sonde measured a pressure of 925mb at an elevation of 4 meters at 1:54am EDT. While some of the data is unclear from the sonde, it may have had wind of 16 knots at the surface. Please visit the NHC for the latest updates: www.nhc.noaa.gov If needed, they would post an update before 5am EDT.
- A disclaimer about SFMR estimated wind data will now appear in the recon system's archive page for an HDOB in some cases.

- I'm writing code to display wind swath over life of storm using track & wind radii. Want to include exact smoothing NHC uses. "smooth wind field depicted on the graphic is produced by a trigonometric interpolation between the four defined radii" (www.nhc.noaa.gov/aboutwindfie...) Anyone know how?
- Using actual wind radii gives results that do not match NHC due to smoothing not being applied. 1st image is NHC smoothed wind swath. 2nd is wind radii based on forecast advisory history (with interpolation; has bugs) 3rd is a smoothed wind field based on equation from AI. But I want exact NHC code.
- After investigating the cause of why our site was operating slowly we have found that the result was a Python script that accessed our site from the same IP address over 12 million times in the past week. We have blocked that IP address and the Python module used.
- Our site is not able to handle that kind of load. After identifying who it was it became clear that the repeated accesses were the result of a misconfigured script and were not meant to be malicious. As part of this process we have made changes to our site's security at Cloudflare.
- At times you may see a CAPTCHA on our site that you must solve to proceed. (sometimes it is automatic) In some cases, you may be temporarily blocked if you are using our site too frequently.

View full threadIf you see significant disruption in connecting to our site, please contact us through Bluesky. As previously mentioned in our last post, certain content has been temporarily removed from our site. Some data will be made available again within a day or so and some should return next year.
- Our site is currently being hit with 30,000 requests per hour hitting the same pages in our recon system, mostly the same recon missions on Erin. It may be a Python script doing it. We're trying to mitigate it & you may be asked to solve a CAPTCHA challenge from Cloudflare before accessing the site.
- There have been 3.9 million requests in the past 24 hours and 11.5 million in the past 7 days. We have moved most of the content on the site so that it is no longer accessible. Some of the content will hopefully return later in the year while some will likely return in 2026 or 2027.
- There was also an unusual amount of traffic downloading large model wind swath files this month in the model system. As a result all older Atlantic content in that system will not return until at least next year when data will be delivered in a different way that hopefully uses a lot less bandwidth.

View full threadAs a note for the future, our site is not designed to be a repository that people check for data with automated scripts. We can't handle that kind of load. We will be redesigning things to help mitigate future incidents, but we still won't have the capability to act as that kind of repository.
- Reposted by Tropical AtlanticA large portion of the Atlantic coastline will see the risk for high surf and rip currents this week due to #Erin. 🟥Risk of Rip Currents is High🟥 Life-threatening rip currents are likely. Swimming conditions are unsafe for all levels of swimmers. Stay out of the water. nhc.noaa.gov/refresh/grap...

- Vast swaths of NOAA will be gone in 2026 if 2026 NOAA budget is passed. Hurricane research will be significantly reduced, with some parts of NOAA that do it being completely eliminated. Important tools used by the National Hurricane Center will be gone. There will be less hurricane hunter flights.
- While Trump administration can't completely reverse progress made over past half century in forecasting, their attempts to do so will nonetheless costs tens of billions more than any money "saved" & will kill thousands. We will have storms intensify unexpectedly & we won't know it as fast as before.
- With what's already cut forecasts will be impacted. If 2026 cuts occur it'll seriously undermine ability for anyone to continue to forecast storms. If you end government & university tools everyone uses, from remaining government meteorologists to private ones, public suffers from degraded forecasts

Some of what could be gone in 2026 if NOAA budget passes: tropic.ssec.wisc.edu realearth.ssec.wisc.edu rammb-data.cira.colostate.edu/tc_realtime/ rammb-slider.cira.colostate.edu
- Imagine ending public release, including to hurricane forecasters, of vital data to see inside storms for fear of data being hacked & released publicly while on its way to being released publicly. That's Trump logic in 2025. If 2026 NOAA budget is passed, there won't be much hurricane research left.
