Forget plain old pollen season; much of the country is in the midst of a pollen tsunami.

The big pollinators, oak and birch trees, are coming out at the same time as seasonal staples like poplar, alder and ash. And grass pollen is on the way.

"It's a triple whammy," Dr. Clifford Bassett, medical director of Allergy & Asthma Care of New York, told NBC News. "The early and mid-spring tree pollen and the grasses are hitting all at once to create misery and suffering."

But even if you're not sneezing and itching, you don't need an allergist to tell you there's a lot of pollen in the air. Here are nine highly visible signs the pollen tsunami has arrived.

1. Cars

If you park outside, even briefly, pollen will overtake your windshield, your hood and pretty much every nook and cranny of your automobile. Car washes do big business during pollen season.

2. Driveways

You really notice how much pollen has accumulated on your driveway once it rains and it gathers in big, icky yellow pools.

3. Birds

4. Bodies of water

Anyone for a swim? Ponds, lakes and rivers are swollen with pollen that is blown into the water or is washed there by rain.

5. Decks

Anything outside gets a coating of yellow dust. Maybe you should keep your shoes on.

6. Body parts

Not sure if there's pollen? Take a swipe and see.

7. Insects

Pollen particles are huge when you're a tiny insect just looking for something to eat.

8. Parking lots

Be prepared to hop over puddles of pollen as you make your way to and from your car.

9. Mushrooms

Nature's tiny umbrella is doing its best to stave off a sprinkle of pollen.
