Irish weather forecast: Met Eireann warns of bitterly cold Monday night with subzero temperatures

Irish weather forecast: Met Eireann warns of bitterly cold Monday night with subzero temperatures Monday will be largely dry with sunny spells apart from the odd showers . A forecaster said: “Highest temperatures of 10 to 12 degrees in light to moderate northwest winds.” However, a frosty Monday night is in store for parts of the country. Met Eireann is forecasting a chilly night with temperatures dropping to as low as -1C, with “some frost inland in little or no wind". © Collins Photos.

That speedier 5G network wireless carriers are promising to build could interfere with the accuracy of weather forecasts.

For months, NASA and the National Oceanic and Atmospheric Administration (NOAA) have been sounding the alarm that wireless spectrum the Federal Communications Commission is auctioning off to use for 5G wireless networks could interfere with data collection used in weather forecasting.

On Thursday, NOAA's acting chief Neil Jacobs testified on Capitol Hill that the interference from new 5G wireless radios could reduce the accuracy of weather forecasting by as much as 30 percent. He told the House Subcommittee on the Environment this would result in coastal residents getting at least two to three fewer days to prepare for a hurricane and could lead to less accurate predictions about where these major storms will make landfall. Such errors in these predictions could cost people their lives, he warned.

The FCC is clashing with scientists who argue that 5 G networks could interfere with weather sensors and compromise weather predictions. If you had a choice between a better, faster cell phone signal and an accurate weather forecast , which would you pick? That’s the question facing federal officials

Forecasters have warned that interference from 5 G radios in the 24 GHz band could reduce the accuracy of predicting the intensity and path of major hurricanes by 30%. That speedier 5 G network wireless carriers are promising to build could interfere with the accuracy of weather forecasts .

The FCC began auctioning off the 24 GHz spectrum in March to wireless carriers who plan to use it for new 5G networks. Earlier this week, Democratic Sens. Ron Wyden of Oregon and Maria Cantwell of Washington wrote a letter to the FCC asking that the agency refrain from issuing the licenses to auction winners until a solution can be found.

The problem comes from the use of spectrum in the 24 gigahertz frequency band, which is very close to a spectrum band that NOAA uses to collect data for weather prediction. NOAA uses the 23.8 GHz spectrum to collect data about atmospheric conditions that's then fed into its data model. The concern is that 5G radios carriers use in the 24 GHz band will interfere with these sensitive sensors on satellites monitoring the atmospheric conditions.

New 5G network could jam weather satellites

New 5G network could jam weather satellites The roll-out of 5G mobile networks could have a big impact on weather forecasters' ability to predict major weather events. Weather satellites use certain radio frequency bands in the electromagnetic spectrum to monitor water vapour in the atmosphere, but bands near these frequencies may also be used by 5G networks. In particular the concern regards the 26 GHz band (between 24.25 GHz to 27.5 GHz) which is being sold internationally as part of the 5G spectrum. Ofcom in the UK is considering putting this band to auction in the future.

Forecasters have warned that interference from 5 G radios in the 24 GHz band could reduce the accuracy of predicting the intensity and path of major hurricanes by 30%. That speedier 5 G network wireless carriers are promising to build could interfere with the accuracy of weather forecasts .

Experts say the new 5 G network will set weather forecasting back 30 years. But how does a cellular network affect our ability to forecast the weather ? Powerful new 5 G transmitters could operate just a hair away from weather signals on "This is not one and done," Gerth warned Wired.

Turning down the power emitted by 5G wireless radios could help prevent some of this interference. But Jacobs pointed out that the current proposal from the FCC would result in a 77 percent loss in data from the NOAA satellite sensors. He said experts from the FCC and NOAA are collaborating to come up with a solution, and he noted he was optimistic a solution will be found.

The FCC didn't immediately respond to a request for comment.

There are other frequency bands the FCC is looking to auction off that could also be problematic for forecasters. The FCC also plans to auction off spectrum near bands NOAA uses to detect other weather conditions like snow and ice as well as other atmospheric conditions.
