Albany, New York – A rare G4 (Severe) solar storm is expected to impact Earth on Jan. 20, prompting heightened monitoring of New York’s power grid and critical technology systems as federal space weather officials track incoming solar activity.
According to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, a coronal mass ejection (CME) launched from the Sun late last week is forecast to arrive late Sunday into Monday. G4-level geomagnetic storms are uncommon and can interfere with power transmission systems, satellite operations, GPS accuracy, and some radio communications, particularly across large, interconnected electrical networks.
New York’s size, population density, and reliance on long-distance transmission lines increase the importance of grid stability during severe space weather events. While the state sits south of the most geomagnetically exposed regions, NOAA officials emphasize that widespread power outages are not expected, though utilities may take precautionary steps to protect sensitive equipment.
For most residents, the solar storm itself will not be noticeable. Experts explain that geomagnetic activity can introduce electrical currents into long transmission corridors, reducing the grid’s margin for error. Grid operators may increase monitoring, adjust system loads, or implement protective measures if conditions intensify.
Cell phone service and internet connectivity are expected to remain largely unaffected. However, minor GPS inaccuracies are possible, particularly affecting aviation operations, marine navigation, and precision timing systems used by transportation and emergency services.
As a visible side effect, auroras may be visible across northern New York, with a lower chance of visibility farther south if geomagnetic conditions strengthen beyond current forecasts.
NOAA forecasters say geomagnetic activity could persist at lower levels into Tuesday.
