The official storm season runs from October to March and NRMA Insurance manager for Safer Communities, Alex Mazzoni urged people to prepare their homes.
"We know that two in five residents are yet to take steps to prepare their homes for severe weather, so we are joining the SES to urge everyone to take time to prepare their homes for storm season," he said.
NSW SES Acting Commissioner, Fatima Abbas, said the SES has responded to more than 3,500 jobs in the past four weeks.
"In these recent storms we have seen countless trees blown over and, in some cases, entire roofs have been blown off homes and businesses," she said.
NRMA Insurance, in conjunction with the NSW SES, has developed a checklist to help people prepare for the storm season. From more information, visit www.ses.nsw.gov.au
