is a very real, powerful Category 5 storm that could soon target the Caribbean islands and South Florida. But the National Weather Service is warning people to watch out for fake forecasts after several went viral on social media.
“Keep your eyes out for fake forecasts. THIS is what an official NOAA advisory looks like. Note: forecast only goes out 5 days,” the agency said on Facebook. They encouraged readers to visit the National Hurricane Center’s official website if you are unsure of the source.
The warning comes after several websites claimed Irma would become a Category 6 storm — which does not exist — that would wipe entire U.S. cities off the map.
“There is no such thing as a typhoon in the Atlantic or a Category 6 or higher hurricane,” WAPT Meteorologist Nathan Scott wrote on Facebook, encouraging users to follow trusted media outlets when searching for information on the storm.
He added, “Meteorologists have not discussed anything about implementing Category 6 criteria because there’s nothing that strong.”
The National Hurricane Center uses the Saffir-Simpson Hurricane Wind Scale, which grades storms on a scale from 1 to 5 based on sustained wind speeds. Category 5 applies to any hurricane with sustained winds of 157 mph or higher — powerful enough to cause “catastrophic damage.”
Another bogus claim was a Facebook post that falsely illustrated the storm on a projected path toward Texas, before any meteorologist knew where the storm would go. The post has since been deleted from Facebook but several meteorologists used this as a lesson to folks looking for information online.
“The fake forecast shows Irma heading southwest of current, real, predictions, and barreling right into Texas, where Harvey, the hurricane-turned-storm, has left record rainfall, devastation and killed dozens,” meteorologist James Spann of WBMA-TV tweeted.
On Tuesday, the National Hurricane Center said Irma was “potentially catastrophic” with life-threatening wind, storm surge and rainfall hazards. It would likely bring these conditions to the Leeward Islands on Tuesday night and the Virgin Islands and Puerto Rico on Wednesday.
In Florida, Gov. Rick Scott declared aand activated 100 members of the Florida Air and Army National Guard to help with planning across the state. Another 7,000 National Guard members will report to duty Friday when the storm could be bearing down, though it’s too early to know exactly where it may hit.
