More hail and thunder will hit the UK today as a week of storms shows no sign of letting up.
And the relentless rain could spell misery for the country's estimated 16 million hay fever sufferers.
Across the country there will be high levels of tree pollen circulating - especially in the south of England.
The Met Office has warned hay fever sufferers that prolonged heavy rain can also cause pollen levels to soar as well as warm weather.
The experts said pollen levels can be high even after rain, explaining: "During a thunderstorm¸ high humidity can split pollen grains, releasing a higher density of pollen into the surrounding air.
"Any rainfall causes a marked decrease in pollen concentration in the air, but the time and amount that it rains during the day is very important.
In the East of England high pollen is expected until at least Thursday, while London and the South East are set to be blighted until the weekend.
Hay fever sufferers in the North West will see some relief, however, as pollen levels will fall as the week progresses.
Brits enjoyed 20C sunshine on Sunday as people flocked to beauty spots and beer gardens as the country continues to emerge from the coronavirus crisis.
But a week of turbulent weather has followed, with more showers forecast across southern England and Wales today and these will move north later in the day, with some bringing hail and thunder.
The spells of sunshine broken up by heavy, thundery showers are set to continue right up to the weekend.
Some forecasters expect temperatures to increase to 25C next week as the storms dry up an lockdown rules are further eased in England.
