Going by the RTÃ‰ weather forecast, the storm is now predicted to mainly pass over the sea below England. Either way, my best advice is be prepared for the possible power cut.
Plug in your laptop, phone, etc. and leave them plugged in during the storm. This way if the power goes out, they will be fully charged from the start of the power failure.
If the power goes out for a long period, e.g. still out before going to bed, switch off your phone (and tablet.) That way they don't waste battery power overnight.
If you have a UPS, shutdown your computer as soon as the power goes out. The UPS will come in handy for powering your router if you'd like to get online during a power cut - Just use your laptop (or tablet, etc.) instead of the desktop. On most UPSs, you can turn off the beep by briefly pressing the power button. The router uses such little power that it'll run for several hours, at least based on my UPS during a previous power cut.
Hopefully nothing gets damaged your way and that the lights stay on.
