Storms have swept through the Central Highlands last night, cutting power to almost 60 homes.
The hardest hit areas were around Lochington and The Willows, west of Emerald, but there have been no reports of damage.
The bureau's Brendan Bradford says more storms are expected this afternoon.
"So that western part of the Central Highlands, Coalfields, is a risk again today and they develop fairly late into the afternoon and into the evening but yes build up to quite gusty storms and there's a possibility we'll see some hail in the those storms as well," he said.
Mr Bradford says there was not a lot of rain in last night's storms.
"Generally 1 to 6 millimetres through that western part of the Central Highlands and Coalfields," he said.
"However, I did receive a report of 21mm at Raymond to the west of Springsure and 6mm at Lochington and they had a 59 kilometre an hour wind gust as that storm came through as well."
Bob Pleash from Ergon Energy says crews are working to restore power as quickly as possible.
"Now we've organised a helicopter patrol to first identify the problem and assess the damage and once that's done we'll serve out acting crews to repair the problem," he said.
