U.S. weather forecasters are the latest group to sound the alarm that the race to introduce 5G technologies may have adverse consequences.

In a letter to the Federal Communications Commission (FCC), U.S. meteorologists called the potential for 5G mobile technologies to disrupt communication between weather satellites "deeply concerning," according to the BBC.

The letter was signed by the American Meteorological Society, the National Weather Association and the American Geophysical Union. They oppose a FCC proposal to share a radio spectrum band with mobile companies, arguing that sharing the radio band may lead to a delay in life-saving data, according to Newsweek. "[Interference will] postpone dissemination of vital information to the public to aid and protect life, property, businesses, and government operations. The loss of seconds can mean the difference between safety and grave risk to life and property," said John Porter, an executive at AccuWeather, in a separate letter to the FCC, as Newsweek reported. Experts warned that sharing the 1675-1680MHz band could cause delays in public service alerts about severe weather like hurricanes and tornadoes. The letter by the U.S. meteorologists piggy backs on a letter sent to the FCC Chairman by Sen. Ron Wyden (D-Ore) and Maria Cantwell (D-Wash.) asking him not to issue 5G licenses "until the FCC approves the passive band protection limits that the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) determine are necessary to protect critical satellite‐based measurements of atmospheric water vapor needed to forecast the weather."
