Damaging winds of more than 95km/h are blasting Melbourne, with the recent rain, warmer conditions and pollen count raising concerns about thunderstorm asthma.

Wind gusts had already reached 95km/h at Melbourne Airport by 6.30am on Monday, but Bureau of Meteorology senior forecaster Stephen King said Melburnians should brace themselves for more to come.

"There's a severe weather warning current which includes Melbourne, with winds gusting to 90km/h to 100km/h, mainly in the morning and through to the early afternoon," he said.

Meanwhile, WeatherZone's four day pollen forecast predicts moderate risk days for Monday and Wednesday and a very high risk day on Thursday, with hayfever and allergy sufferers advised to stay indoors and have their medication on hand.
