HAIL stones and thunderclaps this week served as a reminder for Warwick residents to prepare early for summer storms to avoid property damage.

The Bureau of Meteorology said the stormy weather would clear before the weekend but more storms could be expected as the season gets underway this month.

Warwick SES controller John Newley said said now was a good time for people in the Rose City to ready their homes for storm season.

He said severe thunderstorms were expected to peak in November.

"It's a little bit early but we expect storms to pop up as soon as weather starts to warm up," Mr Newley said.

"Right now it is a good opportunity for people to check their properties and make sure there are no big trees and that there are no leaves in gutters for winters.

"If a gutter is filled with leaves, the water can't flow off and fills up in the roof and comes back down into the house which ends up being very expensive.

"Clearing gutters of leaf litter is also good preparation for bushfire season."

Despite its connection to dry weather, the Bureau of Meteorology said an incoming El Nino weather system would not have any effect on the duration or intensity of the storm season and an average storm season was expected.

Mr Newley said forecasters were yet to brief SES workers on the severity of coming storms.

"We haven't had any brief to say this season is going to be any more than what's normal, but we'll be meeting in the next six weeks with the meteorology bureau to discuss it," he said.

"The SES guys have been concentrating on training for height safety and chainsaw work, and checking our equipment to prepare for the season."

Mr Newley said damage to power lines was common after storms and urged residents to phone 000 and stay clear of fallen power lines.
