Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
830 AM EDT Tue Jun 24 2025

For the North Atlantic...Caribbean Sea and the Gulf of America:

Special outlook issued to update AL90 formation chances

1. Central Subtropical Atlantic (AL90):
Satellite images indicate that shower and thunderstorm activity
has become better organized in association with a small gale-force
low-pressure system located about 900 miles east-northeast of
Bermuda. This system will likely become a short-lived tropical
storm later today before more hostile environmental conditions end
its opportunity for development by this evening. The low is
forecast to move northeastward at around 15 to 20 mph while
remaining over the open central Atlantic. For additional
information, including gale warnings, please see High Seas
Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.




High Seas Forecasts issued by the National Weather Service
can be found under AWIPS header NFDHSFAT1, WMO header FZNT01
KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php


Forecaster Blake


DorkyMcDorkface, those models were right.

I can dig it.

But if a NHC staffer has 22/11/4 you know it's getting a name. 8-)


Looks like the NHC staffer might win this round )unless it totally collapses quickly.

This seems like an unusual location for cyclogenesis. Its on the absolute outer edge of supportive SST's. I know storms have formed further north and east, but this general area of the Atlantic doesn't seem to get much "traffic", at least per my amateur recollection.

Doesn't appear to be tropical. I see forecaster Blake didn't agree with Hagen's 50%. It's 100% certain that there is a closed low and possibly 30-35kt winds. It all comes down to whether the NHC wants to identify the low as a STS or STD before it's torn apart by shear today.

Should have done so 30 hours ago! But I think they're doing it because they're going to extend the time back to that point post season and wanted to give it a name.

For sure at post-season TCR, they add time as a storm as IMO, it has been a TS since 24 to 36 hours prior to advisory.

The very definition of a name waster. It looked better yesterday and might have gotten a post-season upgrade but this will be a 2 advisories and done special.

I couldn't agree more :roll: That's okay though, I was only expecting 13 or 14 Atlantic named storms this year but my S2K Hurricane Season pole prediction was 15/7/2 for this very reason. For many years now, I simply view most Atlantic seasons with an anticipation of one or two fluff-balls being baked into the mix :cheesy:

The most east location of formation, but as I mentioned before, for sure they will extend it's life 24-36 hours at post-season TCR.

Gotta hand it to her though, I never thought she'd be upgraded. She really wanted it! 8-)

Yeah I'm inclined to believe that as well. This has arguably been a TC since Sunday night or so. We already knew it had a solid LLC and there's been periods of sustained convection up until recently.
