No, that viral “Big Tornado Threat” map of Isaias wasn’t a real forecast

An AI-generated graphic of Hurricane Isaias’ tornado threat spread on Facebook, X and TikTok. NOAA said it didn’t match the official forecast, and it put cities in the wrong places.

The Claim

“BIG TORNADO THREAT FROM ISAIAS”

Text over a colorful forecast-style map, presented as Hurricane Isaias’ tornado threat. Similar AI “videographics” of the storm’s path spread on TikTok and Facebook with hundreds of thousands of views.

Our rating

False

The graphic was AI-generated and did not match the official Storm Prediction Center forecast. Isaias did bring a real tornado risk, but this map didn’t show it accurately. How we rate

What's Actually True

The map was made with generative AI, not weather data. AFP reported that OpenAI’s image verification tool found a SynthID watermark in the image, and Hive Moderation rated it likely synthetic.

NOAA spokeswoman Maria Torres told AFP on Oct. 7 that the graphic was inconsistent with the Storm Prediction Center’s forecast for Isaias, and pointed people to hurricanes.gov for official projections.

Meteorologist Chris Vagasky told AFP the AI maps “don’t use any actual real weather data,” and that they showed “Tallahassee where Jacksonville is, Biloxi in both Mississippi and Alabama, and the Florida peninsula labeled as the Florida panhandle.”

Tornadoes were a real, if limited, risk. The National Weather Service office in Greenville-Spartanburg described “a low-end tornado threat” with low confidence for Saturday into Sunday, and The Weather Channel reported a threat of severe storms and tornadoes across Georgia, the eastern Florida Panhandle and the Carolinas on Saturday.

Isaias made landfall near Destin, Florida, Friday evening as a Category 2 hurricane with 105 mph sustained winds, and is now a post-tropical cyclone over the Southeast.

Claim vs. Facts

Where the claim and the facts differ
Point	The claim	The facts
Where the map came from	Presented as a forecast graphic of Isaias’ tornado threat	AI-generated; a SynthID watermark was detected and Hive rated it likely synthetic
Match to official forecast	Implied to show the expected threat area	NOAA said it was inconsistent with the Storm Prediction Center forecast
Geography	A map of the Gulf Coast and Southeast	Put Tallahassee where Jacksonville is, showed Biloxi in two states and mislabeled the Florida peninsula
Tornado risk	“BIG TORNADO THREAT”	Real but limited: NWS Greenville-Spartanburg called it a low-end, low-confidence threat
Current status	Shared widely as a live forecast	The original poster deleted it; copies kept circulating on TikTok and Facebook

How It Spread, and Why It Misleads

The first widely seen version was posted Oct. 7 by Tampa Fox 13 meteorologist Paul Dellegatto, who had a large following and a trusted on-air role. He removed it from Facebook and X after other users flagged errors, writing, “It was trash. So I deleted it,” and thanked the user “for pointing out the inaccuracies.” We credit him for correcting it in public.

Similar AI videographics kept circulating on TikTok and Facebook after the original was deleted, AFP found.

Why it misleads: AI maps look like official products but blend real and invented details. Weather reporter Dennis Mersereau called the graphic “a mixture of real and bogus information blended together.” In a hurricane, a wrong map can send people to the wrong place or make them ignore real warnings.

What to use instead: the National Hurricane Center (hurricanes.gov) and your local National Weather Service office.
