A storm could be-fall us. Colorful leaves and cooler temperatures aren’t the only thing autumn is potentially bringing. Meteorologists predict that Earth could be blasted by a geomagnetic storm on Wednesday due to its timing with the autumnal equinox.

When most folks think of Autumn, browning leaves, crisp wind and pumpkins come to mind – for scientists, though, it’s solar storms. And one is likely to blitz the Earth today, according to meteorologists. A solar storm, also called a geomagnetic storm, sees material spewed from the sun bombard the planet’s magnetic field.

Charged particles crashing into Earth are expected to create strong solar storm conditions early Monday morning, prompting a Geomagnetic Storm Watch as the Northern Lights could be visible farther south than usual.

If it hits as night falls in the U.S. on Monday, aurora could be visible as far south as Iowa and Pennsylvania. If it arrives earlier, northern Europe could see the display.

Northern lights could be visible over mid-latitudes across the US and Europe tonight, Sept. 16. A geomagnetic storm watch has been issued by NOAA's Space Weather Prediction Center.

Vibrant auroras could be visible as far south as Oregon and Pennsylvania tonight as Earth reels from a "strong" G3-class geomagnetic storm. However, the nearly full Harvest Moon may complicate viewing opportunities.

Coronal mass ejection from the sun at the same time as a recent X4.5 solar flare is about to collide with the Earth.

The northern lights may be visible again after a geomagnetic storm Monday night allowed them to be seen as far south as Texas.
