I think yes Humberto is going to pull it away

This is PRECISELY why folks can't take just one forecast and use it as gospel over a period of time.

The models for #TD9 were super tricky, and 48 hours ago we were thinking about a landfall in the Carolinas as a possibility.

Now it's going to take a literal right turn!

“If it hits you, it’s just not your day.”

90% of people struck by lightning survive but many have lifelong injuries. We still see around 20 deaths from lightning every year in the U.S.

We’ve seen 5 deaths in the U.S. in September alone.

Dave Portnoy sounds off about lightning delays in college football.

"Lightning, if it hits you, it's just not your day."

The best course of action right now remains to continue monitoring your trusted sources for forecast updates, especially in the Bahamas and along the coast in the Carolinas, and ensure you have hurricane plans prepared in case of major impacts. (graphic from NHC)

Here is our evening update on Potential Tropical Cyclone 9, a system likely to become Imelda, hit the Bahamas, and then threaten the coastal Carolinas with very heavy rain. Details on the rainfall scenarios.

Potential Tropical Cyclone 9 looking like it's going to be a serious rainstorm for the eastern Carolinas

The goalposts of possible rainfall totals in the Carolinas are quite wide

The tropical wave labeled 94L (no, I won't name it in advance) has warm water, moderate to low vertical wind shear, and plenty of moist air ahead of it. The system is partly over land today, delivering heavy rain and gusty winds to the Dominican Republic, Haiti, and the Turks and Caicos Islands.

Line plots of area-averaged daily sea surface temperature (SST) in the subtropical North Atlantic as of September 25, 2025. Black shows the 1991-2020 average, red shows 2023, orange shows 2024, and blue shows 2025 (so far). An inset map depicts September 25th's map of anomalies, where the dashed box represents the averaging region used to make the line plot values. These are computed from NOAA's OISST dataset using Python.

Infrared image from UW-CIMSS for 1420 UTC on 26 September centered on 94L (the "I" label) that also shows 200-850-hPa (deep layer) vertical wind shear. Green contours imply weak shear, yellow imply moderate shear, and red imply strong shear. Higher vertical wind shear tends to get in the way of tropical cyclone development.

Map of total precipitable water derived from microwave imagery by UW-CIMSS for 1100 UTC on 26 September centered on 94L (the "I" label). Higher values (orange, brown, pink colors) imply more moist air, and more moisture can support the thunderstorms that "power" a future tropical cyclone.

While the #Helene anniversary has been traumatic for most in the area (and the tropical situation isn't helping). the use of photography is important tel tell the story.

And as media will come and go with the anniversary, the stories should still be told, so we do not forget.
