Well, your symptoms correspond almost perfectly with the beginning of ragweed season, so I suspect that's what's going on. Usually rain knocks down allergens, but apparently the hurricane just stirred up the pollen even more.
(I was outside for FIVE MINUTES, just to check the neighbors, and I STILL feel like someone's sitting on my chest. Asthma hasn't been that bad in MONTHS.)
You could try some OTC antihistamines such as Zyrtec or Allegra. If it's still bugging you in a few days, or if the chest thing is still bad tomorrow, see a doctor.
