Hurricane Irma Is Not A Cat. 6 Storm - There's No Such Thing
MIAMI (CBS4) - A lot of fake Hurricane Irma forecasts are circulating around the internet.
The National Weather Service is warning people not to fall for them after several went viral.
"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.
The warning is a result of some websites claiming Irma would become a Category 6 storm.
There's no such thing.
The Hurricane Center uses the Saffir-Simpson Hurricane Wind Scale, which grades storms between 1 and 5 based on their sustained wind speeds.
Hurricane Irma is a Category 5 because its wind speeds are 157 mph or higher.
