Now days the rains are unpredictable as it shines hot in the morning and noon and by late afternoon the rain starts with thunder storm. Normally we cannot see the thunder as we can only hear the sound late. We should not see the lightening with naked eyes as it may spoil vision permanently. My elders used to say that during thunder storm we should not take refuge under the tree especially the coconut tree, which is vulnerable to take in the thunder to its fold. I have seen many coconut trees destroyed with fire from thunder ball and it wont regrow again. Never venture out during thunder. Even after the rain has subsidized , we have to be careful while wading through pool of water as there are every chances of electric wires getting snapped due to thunder storm and wind and thus there are every chance of current passing to body through broken wires inside the water.
