Government cuts off vital satellite data for hurricane forecasts

In the United States, concerns have emerged over the impending cutoff of crucial satellite weather data, set to take effect on June 30, 2025. The U.S. Department of Defense has announced that it will cease sharing data from weather satellites, which has been relied upon for hurricane forecasting for over 40 years. This decision has raised alarms among meteorologists and scientists, as the data is vital for tracking storm formation and intensity. Despite the announcement of a delay to July 31, there are growing worries about the implications for forecasting accuracy as the peak of hurricane season approaches. The specific data affected is derived from a Defense Meteorological Satellite Program, utilized by the National Oceanic and Atmospheric Administration (NOAA) and the National Hurricane Center. This microwave data provides essential three-dimensional insights into the structure and behavior of storms, particularly crucial at night. Experts have indicated that without this data, there will be significant gaps in real-time monitoring of storm conditions, which could hinder forecasting capabilities and potentially endanger millions along hurricane-prone coastlines. Many researchers have highlighted the urgency of such data as hurricanes are expected to become more frequent and intense due to climate change. They stress the loss of microwave data will impede the ability to predict rapid intensification of storms and their potential paths, a development that heightens risks for those living in vulnerable areas. Even though NOAA has assured the public that alternative sources of data exist, professionals in meteorology assert the cutting off of such critical data comes at a precarious time, just as seasonal forecasting becomes challenging with increasing storm activity. The decision to decrease the flow of vital satellite information has reportedly been linked to cybersecurity concerns rather than funding issues. Despite making these precautions, experts express skepticism about the adequacy of alternative data sources, especially with forecasts for an active hurricane season in the forthcoming months. There are calls for more transparency regarding the reasons behind this policy change and its broader implications for climate monitoring and public safety as the hurricane season continues up until November 30.
