    Levels could rise: Pollen could boom after rain

Levels could rise
Pollen could boom after rain

With rain falling you would be right to think that pollen levels are lower, but once the rain clears we may see a boom.

No matter the time of year, rainfall will dampen pollen easing the amount in the air. While levels will generally be lower, raindrops can kick up grass and weed pollen, just not to a significant amount.

Despite this, thunderstorms can also result in greater pollen density due to the humidity that accompanies them causing grains to burst.

Winds then lift the released pollen and carry it far away. As warmer and drier conditions return, grains and grass which have swelled over the past few weeks will begin to release their pollen.

So with strong winds in the forecast throughout Tuesday and Wednesday, in addition to thunderstorms in the wake of Tuesday's persistent rain, pollen will be something to watch out for.

You can stay on top of the pollen levels in your area at any time here in the Weather & Radar app with our dedicated pollen feature.
