28/5 -30/5 Geomagnetic storms - how concerned?

Are we likely to see GPS scintillation errors over the next three days with this A index level of geomagnetic disturbance Space Weather: Geomagnetic Disturbance Index

As RAIM is predicated on the assuption that a majority of the GPS constellation is operating properly it may not even be able to detect a loss of integrity (let alone provide corrections).

At what level A index level does this become an issue?

Also what level are coms frequencies likely to be affected?

I understand the Americans and some UK carriers are notified of these events but it doesn't appear in our NOTAMs. Does anyone else in the UK have this stuff promulgated?
