SES crews in Bendigo and Castlemaine have had four call outs between them this morning.

An SES spokesman said the call outs were in relation to building damage or leaking roofs.

He said it was important residents ensured their properties were prepared for winter.

"Leaking roofs is one of the more common causes of damage (from rain)," he said.

"We are expecting more rain of next few days and given it has been quite dry start to year, we would encourage everyone to check their gutters, down pipes and drains to make sure they are clear of leaves and debris."

8.20am

Areas across central Victoria have welcomed rainfall this morning.

Charlton has had 8.4mm fall since 3am, Redesdale has received 5.8mm while Yandoit (20km north of Daylesford) has received 6.6mm this morning.

Bureau of Meteorology duty forecaster Steve McGibbony said further showers and storms could develop this afternoon.

"There's a band you can see on our radar coming through that has brought that 8mm to Bendigo," he said.

"There is nothing beyond that on the radar but we are expecting unstable conditions (later today).

"It could mean further showers and stops could develop before clearing this evening.

"More rain is developing in the west that could move in tomorrow."

7.50am

May 1 now has the year's highest daily rainfall total so far, with 8.4mm falling in Bendigo by 7.50am.

7.30am

Bendigo is on track for its highest daily rainfall total so far this year.

By 7.30am on Wednesday, 7.8mm of rain had fallen on the city.

The rainfall means May's total has already surpassed the January, March and April monthly totals.

The current highest daily total for 2019 was on February 7, when 8mm fell. The Bureau of Meteorology measured 10.6mm for the city for the whole of February.

Last year, Bendigo measured 51.2mm of rain in May.

Earlier

BENDIGO has already received more rain on the first day of May than it did for all of April.

Bureau of Meteorology data showed Bendigo received only 3.2 millimetres of rain in April, with the majority of that total coming on a single day earlier in the month.

Bendigo received 3.6mm of rain between 5.30am and 6.30am on Wednesday.

The bureau predicts up to 20 millimetres of rain for the region in the next few days.

The city also received only 24.2mm in the first quarter of 2019 - the driest start to the year since 2004.

"At this stage it does look likely that Bendigo will be getting some rain over the coming days," bureau duty forecaster Chris Arvier said. "But there is some uncertainty around the totals or where the rain will go."

The bureau expects around 10-20mm to come through the Bendigo region on Wednesday and Thursday.

That would be more than the entire total rainfall in March, when only 6mm was recorded in the region.

Mr Arvier said it was also "not out of the question" for rain totals to be higher than 20mm.

"It is a little bit out of the blue considering the conditions we've had this year," he said.

"But it will definitely be welcome especially for people in rural areas who have been waiting for autumn rains.

"It look likes a significant band of rain will come across the state with parts of the Wimmera and Mallee region likely to receive large rain totals.

"The heaviest hit region will be the north-east on Thursday with some isolated areas receiving up to 100mm of rain."

Mr Arvier said possible storms could affect rain totals in the Bendigo region.

"We might see some changes to the forecast over the coming days," he said.

"It certainly will be wet just still not sure how or where the rain will land."
