Lightning and thunder. Again today the lightning and thunder. It is very unusual for Guam to get so much lightning. This unusual weather started almost two weeks ago. It rarely thunders on Guam, even during the height of rainy season. Some unusual atmospheric conditions must be to blame. I am going to search about on the internet and see if I can get an answer to this question. Or perhaps I will seek the answer to the question’s opposite: Why is there usually so little lightning and thunder on Guam.
