Christchurch City Council is moving temporary pumps into the Southshore and Flockton areas as forecasts suggest the city could be hit with more heavy rain.
The forecasts are constantly changing but it is possible Christchurch and Banks Peninsula could get as much as 50mm of rain over the next 24 hours.
Council Land Drainage Operations Team leader Tim Joyce said tomorrow morning’s high tide, due at 9.30am, was expected to be lower than it was during the rain event which caused flooding in Southshore and in low lying areas around the rivers last month.
The storm surge was also expected to be lower so there was unlikely to be same storm-surge driving flooding that occurred in that event.
However, there was the potential for some street flooding tomorrow in low lying areas near the rivers.
“Council staff are closely monitoring the rain event and will respond as needed,’’ Mr Joyce said.
Pumps have been deployed in Flockton and Southshore and roading crews were on standby to put out flooding signs and close roads as required, he said.
