SEVERE storms with the chance of winds gusting to 90km/h and large hail are forecast for the Sunshine Coast later today.

Bureau of Meteorology forecaster Rosa Hoff said a southerly change moving up the coast through the day would combine with moisture pushed in over the region by east, north-easterly conditions.

She said significant gusts, potentially up to 90km/h, and large hail were expected with localised rainfall to 30mm and higher for those directly under a storm.

Ms Hoff said there was a significant chance of the extreme weather event manifesting. Storms were expected to form inland and then track towards the east.

The Bureau of Meteorology will issue warnings as the situation developed.

There was less of a chance of storms Thursday although the potential for thunderstorm activity will continue.

Ms Hoff said temperatures would increase during the seven-day forecast period with inland areas the hottest.

Nambour, which is expected to hit 33C today, will drop to a 28C maximum Thursday and then reach 30C on Friday, 31C Saturday, 32C Sunday and Monday and then 34C next Tuesday.

On the coast, Sunshine Coast Airport will reach 30C today, 27C Thursday, 28c Friday and 29C Saturday before climbing to 31C Sunday and Monday, and 32C Tuesday.

Maleny, Noosa and Caloundra will all reach 33C by Tuesday.

Mostly sunny conditions will persist for the next seven days with light winds early followed by north, north-easterly conditions through to Monday when they will then swing north-west.

Tropical Cyclone Rita, east of Vanuatu, has downgraded to a low-pressure system and posed no threat to the Queensland coast.

However, Sunshine Coast Daily weekend surf forecaster Mike Perry said it would generate an increasing easterly swell through the week.
