Cork City Council issued a warning to the public on Friday, stating that due to a period of high astronomical spring tides, the low-lying city centre is at risk of flooding.
The warning, in place from Saturday, has been extended until Wednesday.
Areas at the most risk are the South Terrace, Morrison's Quay, Trinity Bridge, Union Quay, Wandesford Quay, Frenche's Quay, Crosses Green, Lavitt's Quay and Kyrl's Quay.
High tide times of note are as follows: Monday 19:37; Tuesday 07.59 and 20.19; Wednesday 08.42.
On Thursday Lorenzo (currently predicted to be a tropical storm at this stage) is likely to be in the vicinity of Ireland's west Coast.
Met Éireann has stated that the impact on Ireland is yet to be determined:
"It's exact track and central pressure is very uncertain as is the timing.
"It is possible it could track to the West of Ireland."
The Irish Meteorological Service is currently monitoring the storm's progress, however:
"The risk of severe weather continues and the progress of Lorenzo and any potential impacts for Ireland are being closely monitored by Met Eireann."
