Although, http://www.spaceweather.com/ only states:

THE SOLAR WIND HAS ARRIVED: As predicted, a stream of solar wind has reached Earth on July 31st-Aug 1st and is gently buffeting our planet's magnetic field. The gaseous material is flowing from a hole in the sun's atmosphere. High-latitude sky watchers should be alert for auroras, especially in the southern hemisphere where winter darkness favors visibility.

Suspicious0bservers notes the coronal holes and correlates them with earthquakes also that the solar wind could be higher on the 29th and shows the solar winds to be calm along with the presence of a large plasma filament on the 30th

According to the Express

Website Space Weather said: “A hole in the sun’s atmosphere is turning toward Earth and spewing a stream a solar wind in our direction.

“Estimated time of arrival: Jul. 31st or Aug. 1st. High-latitude sky watchers should be alert for auroras on those dates.”

However, the consequences could be far more serious than the appearance of the northern or southern lights.

For the most part, the Earth’s magnetic field protects humans from the barrage of radiation, but solar storms can affect satellite-based technology.

Solar winds can heat the Earth’s outer atmosphere, causing it to expand.

This can affect satellites in orbit, potentially leading to a lack of GPS navigation, mobile phone signal and satellite TV such as Sky.

Additionally, a surge of particles can lead to high currents in the magnetosphere, which can lead to higher than normal electricity in power lines, resulting in electrical transformers and power stations blow outs and a loss of power. The higher amounts of radiation can also leave people vulnerable to cancer.

So it's just being asserted that it could be worse, not necessarily that there's any evidence that it will.
