STORMS across the Shoalhaven and South Coast on Monday night resulted in Nowra receiving almost double September’s average rainfall and widespread minor flooding.
Shoalhaven SES responded to 13 calls for assistance between 10pm Monday and 11.30am Tuesday.
Most of the calls were for leaking roofs and downed trees. The volunteers responded to calls from the Berry area to Sussex Inlet.
Conditions on the roads became dangerous with minor flooding and fallen trees.
At about 7am on Tuesday in Gerringong, Fern Street at Belinda Street was closed in both directions due to flooding.
The Princes Highway was closed in a number of areas between Bewong and Moruya due to collisions, flooding and trees across roads.
On the trains, commuters on the South Coast line were advised to allow additional travel time due to the wet weather monitors being activated earlier at Helensburgh.
The Bureau of Meteorology had forecast damaging winds around 65 km/h with peak gusts of 100 km/h and heavy rain which was predicted to lead to flash flooding.
Large surf was expected to cause localised damage and coastal erosion.
During Tuesday morning the Bureau of Meteorology issued a flood watch for the coastal areas south of Nowra.
The rain was heavy enough in Nowra to break the September record.
The town received 73mm of rain from 9am Monday to 9am Tuesday.
That, combined with falls over the weekend, took the total for September to 94.2mm, easily eclipsing the average rainfall for the month of 37mm.
The region also experienced some strong winds with gusts up to 44km/h.
On average rainfall is received on 8.6 days for the month, but to date in 2013 rain has only fallen on five days.
It is the wettest September in more than 10 years, bettering the 57.4mm recorded in 2004.
On average the Shoalhaven receives 656.2m on 93.4 days, but so far in 2013 the area has experienced 1022.8mm with rain falling on 90 days.
