2 January 2014 Last updated at 19:49 GMT
Forecasters are warning that storm force winds and some of the highest tides in decades will add to flooding problems in Wales.
A severe flood warning has already been issued for Barmouth in Gwynedd on Friday morning - the highest level of alert, with risk of danger to life.
Earlier on Thursday, the River Towy burst its banks in Carmarthen.
