  5. The National Hurricane Center's #NHC Forecast Verification Report for the 2025 #Hurricane Season is published. nhc.noaa.gov/verification/pdfs

  6. Kat-5-Hurrikan #MELISSA nähert sich #Jamaika und wird dort in den nächsten Stunden auf Land treffen.
    Ein Flieger der Air Force Reserve Hurricane Hunter meldete um 14 Uhr (MEZ), dass sich MELISSA weiter verstärkt und nun 1-min. Mittelwinde von bis zu 290 km/h aufweist! Der Kerndruck wurde auf 896 hPa geschätzt!
    Dazu rechnet das #NHC (National Hurricane Center) in Jamaika bis Mittwoch mit mehreren hundert l/m² Regen, was zu katastrophalen Stutzfluten und zahlreichen Erdrutschen führen wird.

  7. Melissa is, now, very much a picture perfect hurricane, 901mbar and 175mph/280kmh sustained winds at the core vortex walls.

    The IR signature is scary, but it shows a slight cooling of the core vortex. This means the storm has stopped "feeding" is will hopefully start dissipating energy, as it drags over landmasses. Unfortunately, that energy will be dissipated by wrecking #Jamaica and #Haiti.

  8. Track of Melissa has taken the storm much more west ward than I hoped, and it's smack S off of Jamaica island. This means the ENE stream which WILL push it NE will go through the most populous area.

    Latest estimates put the storm going much further NE, because the ENE stream has solidified and grown stronger, maybe due to Tropical Storm Sonia bumping a mass of air, WSW off Mexico.

  9. Oooph.

    Jamaica, Haiti and Cuba are NOT ready, nor prepared for this. Trop Storm Melissa is slatted to gather more water, energy and turn into a monster storm, meandering between the Greater Antilles.

    That dark spot on the IR image is very hot air rising, sucking the storm in, along with more moisture. It's hurricane super food.

  11. Tropical Storm Jerry, soon Trop Cyclone, is turning, due to top shearing, it seems.

    Thankfully, Bermuda might not get dead-on hit, but still suffer edge of the vortex. Leewards and Puerto Rico may get a Trop Storm bash of rain, but most of the peak energy of the cyclone will be spent on open waters. Bermuda should get trop storm winds by late Friday evening, rain lasting until early morning Monday.

  12. A reminder.

    NOAA/NHC employees are considered critical. Thus, they remain at work. Yes, even without pay.

    It's NOT a "paid vacation" as some MAGAty douchebag reputincan alleged. It's dedication to service, and the HOPE that they will get paid, and not get their house repossessed/be evicted, children starve, etc.

  14. I keep NOT liking this one.

    Where it is, the way it's shaping. It's very unlikely to hit Fla shores, buuuuuuut I am twitching.

    Remember NOAA is a Common good, an amazing, quasi miraculous system of assets and experts monitoring weather to protect us, not only US but about half of the Earth, and the #MAGAts #GOP wants to destroy it to fill their pockets.

  18. Critical #Hurricane Monitoring Data Is Going Offline
    #NOAA has said that in the next few days it will stop providing data from #satellites that have been helping hurricane forecasters do their jobs for decades, citing “recent service changes” as the cause.
    The loss of access to the data could hamstring forecasters’ ability to track #hurricanes and warn residents of their risk.

    #TropicalStormSara remainders still haunting the W of #Yucatan peninsula, after an unwelcome pour of rain over countries in the area. The outcome in flash floods, landslides and other storm related incidents still has NOT been assessed.

    Remember, the countries in the area do NOT have much in surplus or resources allocated to prevention, and handling damage to infrastructure (or much infrastructure, to start with). Spare a thought for them.

    #TropicalStormSara bringing heavy rains inland, as it skims N coast of Honduras.

    Remember, #NWS NHC NOAA are a public service of the US govt, a Common Good funded by tax payer, and the inbound #tRump regime plans to dismantle it and turn its most basic services to private subscription.
