The world has been told to prepare for a severe geomagnetic storm which could bring chaos to cellphone networks, GPS and power grids on Friday.

The severe solar storm is currently blasting Earth and it could stress power grids according to the National Oceanic and Atmospheric Administration

The NOAA issued an extreme geomagnetic storm watch for the next two days after the sun released a powerful a explosion of energy on Tuesday. It comes as the US is dealing with disruptions from Hurricane Milton that just hit Florida.

The Mail Online reports: The level 4 geomagnetic storm began hitting Earth at around 9:30am ET and is expected to continue through Friday. 

It could cause radio blackouts, satellite disruptions and GPS issues. 

It may also damage or disrupt the power grid, which could add more misery as America reels from the devastating aftermath of Hurricane Milton.

G4 storms warnings are rare, marking this only the second one that NOAA has issued since 2005. 

New York City officials are among those warning the public about the impending G4 storm.

Aries Dela Cruz, a spokesperson for New York City Emergency Management, said: ‘We’re monitoring for effects, but the public doesn’t need to take any actions at this time.

‘We obviously don’t want to alarm people. We just want people to not be surprised if their Google Maps stopped working or anything like that.’ 

Sunspot AR3848 – a dark, fast-growing region of strong magnetic fields on the sun’s surface – produced a strong X1.8-class solar flare, which can trigger blackouts and stress the power grid.

Solar flares are powerful bursts of radiation that come from a release of magnetic energy associated with sunspots. They are the largest explosive events in the solar system. 

After the solar flare erupted, a second blast of high energy particles and solar plasma made a direct line for Earth. This is called a coronal mass ejection, or CME.

The CME is what is causing the G4 storm.
