There was a big drought in March...could this have had something to do with it?

There's been a big drought in July ...could this have had something to do with it?

Then it rained this evening & I got all the symptoms: dry tickly cough,running eyes & nose.

just after the thunderstorm this evening, I noticed a very strong petro-chemical smell in the air in ellesmere port where i worked tonight.

did the rain bring down the funes & kick up the dust?
