Flooding unlikely despite heavy rain

Flood-weary residents in Christchurch can breathe a sigh of relief as overnight rain begins to clear.

About 25mm of rain fell over the city between 4pm yesterday to 8am today, the Metservice said.

Forecaster Melissa Roux said the rain was becoming "patchy" over Christchurch from 8am. 

"There is an improving trend. Most of the rain looks like it's moved off to the north already," she said.

The rain was forecast to clear completely by the early afternoon, but the city was still expected to remain mostly covered in cloud for the rest of the day. 

Brief showers were forecast tomorrow morning, but fine weather was forecast for the rest of Thursday, Roux said.

A high of 12 degrees Celsius was expected both today and tomorrow, dropping down to 5C overnight. 

Today's rainfall was much less than the events that caused widespread flooding across Christchurch in recent months. 

The storms that caused flooding on March 4 to 5, April 18 and April 28 all brought more than 60mm of rain to Christchurch.
