MILWAUKEE (AP) -- Someone has been submitting fictional reports of severe weather to the National Weather Service, causing unnecessary alerts and frightening people.
The areas affected have included Milwaukee, La Crosse, Chicago, and Lincoln, Illinois
The person started sending reports in mid-April through an online form on the service's Web site.
Tom Schwein, chief of the National Weather Service's systems and facilities division for the central region, says this person seems to know about severe weather reports.
He says the person usually submits the false reports when severe weather is already present, which makes it more believable.
Schwein says investigators have traced the Internet protocol address of the faker's computer. He says the F-B-I is helping subpoena records to figure out who is registered for the computer IP address.
